1.3 History of Gas Detection

Attempts at gas detection started in coal mines, where the hazards of explosive atmospheres, Oxygendeficiency, and toxic gases were responsible for a high mortality rate among miners. Open flame lampswere used as the earliest warning method—they burned brightly in the presence of combustibles or dimlyin a low-Oxygen environment—but too often they ignited explosive atmospheres.

Caged birds (the origin of the phrase “canary in a coal mine”) were also tried as a means of early warn-ing. Some species of small birds would collapse in Oxygen-deficient or toxic conditions sooner thanhumans; the condition of the bird indicated the need to evacuate. This approach also had drawbacks;some birds were not as sensitive to these conditions as humans, again resulting in miner deaths.

In 1925 Dr. Jiro Tsuji of the Physical and Chemical Research Institute in Japan developed an interferom-eter; an “explosive meter” based on light-wave interference. This invention was the cornerstone achieve-ment in modern gas detection, combining accuracy, safety, and reliability. Dr. Tsuji later founded RikenKeiki Co., Ltd, a world leader in all types of gas detection.

In the USA, the catalytic combustion gas sensor, and the first gas meter, (the J-W gas indicator) was devel-oped in 1927 by Dr. Oliver W. Johnson. This research and instrument development was sponsored byStandard Oil. In 1926 there were several explosions of ships tanks, and it was recognized that somemethod of testing for this hazard was badly needed.

Since the early years, gas detection technology has advanced tremendously. Riken Keiki has alwaysmaintained their leadership in this industry by remaining on the forefront of sensor research and instru-ment development.

1.4 Reasons For Detecting Gas

Gas Detection is often necessary or desirable for a number of reasons. The use of a gas monitoring sys-tem, with appropriate action taken if dangerous levels of gases are detected, can help to prevent an explo-sion or can help to prevent worker injury or exposure to toxic gases. Action can be taken, and initiatedautomatically by the gas monitor, to help prevent the gas level from rising further. Such action could bethe automatic shutoff of gas valves, turning on a ventilation fan, shutting down a process, or audible andvisual alarms to alert and evacuate personnel. In some situations, the gas monitor is used for process con-trol. RKI gas monitors are generally intended for worker and plant safety, and are not intended for processcontrol use where high levels of gases or vapors may be present all the time. Some examples of commongas monitoring applications are as follows:

1.4.1 Flammable gas detection for worker and plant safety:

Flammable gases and vapors pose a threat of explosion, which can maim or kill personnel andcause property damage. Typically first alarm levels are set to 10% LEL (this is 10% of the amountof gas necessary to cause an explosion, and is the OSHA mandated first alarm level). If gassources are automatically shut off, or ventilation fans turned on, it can prevent the gas level fromreaching a potentially flammable level.

1.4.2 Oxygen detection for worker safety:

The Oxygen level in normal fresh air is approximately 21% Volume. Reduced Oxygen levels cancause dizziness in workers and potential passing out. If levels are too low it can cause seriousbrain damage or death. In some working or underground environments, low Oxygen conditionscan be formed either by displacement of the Oxygen by another gas, or by consumption of theOxygen in the area by a chemical or biological process. An Oxygen monitor can help to preventinjury or death by providing an early warning of reduced Oxygen concentration. Typically a lowOxygen alarm is triggered if the Oxygen level drops below 19.5% Volume (the OSHA mandatedlevel), and personnel can be evacuated until the problem is properly investigated and resolved.

1.4.3 Toxic gas monitoring:

Toxic gases such as H2S or CO can be present in refinery or petrochemical applications, parkinggarages, and many other situations. Monitoring of these gases, and appropriate action taken ifalarm levels are exceeded, can help to prevent injury or death. In Semiconductor plants, and manyother plants and factories, often (toxic) gases are used in a process or can be generated by aprocess. Monitoring of these gases can help to alert personnel to potentially dangerous situations.

1.4.4 Duct or Tool Monitoring:

In Semiconductor plants, many highly toxic and flammable gases are used in the manufacturingprocesses. Gas cabinets, valve manifold boxes, and semiconductor fabrication tools, are gener-ally heavily ventilated with ducts drawing air away from these devices. Gas monitoring of theexhaust ducts can provide an early indication of a leak prior to its entering the general work spacewhere it could endanger worker health.

1.4.5 Many other applications:

Many plants, factories, tunnels, parking garages, underground vaults, storage facilities, and a widevariety of other situations, have the potential for having dangerous gases or vapors present. RKIoffers a wide selection of equipment to enable us to solve almost any gas monitoring safety relat-ed application.

1.5 RKI / Riken Benefits

Riken Keiki Co. Ltd. is over 55 years old and has more experience with semiconductor gas monitoring thanany other company. A large staff of engineers and scientists constantly develops new techniques of gasdetection, and also improves existing techniques. They have developed gas monitoring technology thatis unique to solve specific application problems for the semiconductor industry. Here are a few examples:

1.5.1 Hydrogen Detection

For Hydrogen detection in semiconductor applications, Riken has developed a unique hydrogenspecific solid state sensor. It has a very sensitive range of 0-2000 ppm for hydrogen, and the sen-sor has a molecular sieve to make it very specific to just hydrogen. In other words, you will notget interferences or false alarms from any other gases such as IPA, which historically can causea problem in semiconductor plants. We believe no other manufacturer offers specificity like this.

1.5.2 Silane Detection

Detection of Silane gas leaks can be hampered by the fact that if the leak is substantial, the silanegas spontaneously combusts upon contact with air. Sensors that are looking for Silane gas can-not detect the gas after it burns, and there have been serious fires at semiconductor plants due tothis. To solve this problem, we offer a unique detector/transmitter that has two different types ofsensors in it. It has a conventional electrochemical silane sensor, and it also contains a specialionization chamber that detects the SiO2 particulates produced from combustion of SiH4. Noother manufacturer offers this capability.

1.5.3 NF3 Detection

For Nitrogen Trifluoride detection we utilize a pyrolyzer heater to break down the NF3 to be detect-ed as NO2. Our field proven pyrolyzer works extremely well and the replaceable heater elementhas a life of at least two years. We have thousands of these in operation worldwide, and we feelthere is no other similar system on the market that approaches the reliability of our Pyrolyzer.

1.54 TEOS

We offer a unique TEOS monitor that has no interferences from IPA or other commonly troublsomeinterference gases. Out TEOS detector utilizes a pyrolyzer to convert the TEOS to SiO2 then anionization chamber to detect the SiO2 particulates. This provides a trouble-free (no interference)detector for TEOS.

1.5.5 Detection Capability and Ranges

Compare our detection capability and ranges to those of other manufacturers, and you will findthat we offer the best selection of gases and ranges in the industry for semiconductor gas moni-toring.

1.5.6 Long Life Sensors

Long life, stable sensors are our strongest point. Our sensors are all built and tested under rigidconditions. Excellent design and quality control assures that our sensors will easily last over twoyears, and it is not uncommon for them to last more than 3 or 4 years in some cases. As a result,your sensor replacement costs will be low with our equipment.

1.0 Introduction

1.5.7 No Zero Drift

Zero drift can cause costly false alarms. Our systems, and our new GD-K11D detector/transmit-ter, contain unique electronics and software that effectively eliminates zero drift. Our monitors candetermine the difference between long or short term zero drift of the sensor, and an actual gas sig-nal, and they eliminate drift. This means that whether you use our systems complete, or use ourtransmitters to tie into a PLC system, you will not have false alarms caused by zero drift.

1.5.8 Long Calibration Frequency

The high stability of our sensors means that calibration is required only every 6 months. Thisagain helps to keep maintenance costs as low as possible.

1.5.9 Speed of Response

Our systems provide extremely fast response. For most gases, T60 response time is less than 10seconds. We recommend the use of sample draw detectors for most semiconductor applications.Since the sample is drawn in and forced directly onto the sensor, the response is very quick; gen-erally faster than using a diffusion sensor. Especially for gases that are strongly absorptive, (suchas HF, HCl, and F2), diffusion sensors from other manufacturers generally have low sensitivity andslow response to such gases.

1.5.10 Accuracy

Our sample drawing heads provide higher field accuracy than most diffusion techniques can.When a diffusion sensor is calibrated, it must be either lowered into a container of gas sample, ora gas sample can be flowed onto it by placing a test cup over the sensor. The first of these meth-ods is stagnant and depends on the gas molecules diffusing to the sensor. The second methodactually forces the gas onto the sensor, which causes a different reading than using the firstmethod. Also, if gas is flowed onto a sensor face, the velocity and angle of the flow are critical indetermining the sensor signal output. So, when you install a diffusion sensor into a room, the sig-nal from the sensor will depend on the placement of the sensor and the gas flow velocities acrossit’s face. Likewise, for a sensor installed into a duct or other enclosed compartment, the speedand direction of the airflow can greatly affect the signal output from the sensor. Since our sampledraw heads always present the gas to the sensor in the same way, both during calibration andactual use, there is no concern of the external airflows affecting the accuracy.

1.5.11 Maintenance

Our new GD-K11D sensor/transmitter is designed so that maintenance is very quick. The sensorcan be replaced in less than one minute without the use of any tools. The pump also can bereplaced in less than one minute. Both the sensor and the pump are designed for long life so aminimum of servicing will be required.

1.5.12 Manufacturing Capability

Riken has enormous sensor manufacturing and test capability, making approx. 50,000 sensorsper year of all types. Also, since the company has over 600 employees, we generally can get youwhat you need, when you need it.

1.0 Introduction


6

The gas detection industry, like many other technical industries, uses some terms and abbreviations that requiresome familiarity with basic concepts. The following sections divide gas detection into three broad areas:Combustible Gas, Toxic Gas, and Oxygen Deficiency. In addition, several properties of gases and vapors are dis-cussed to give the reader a general background on gas nature to assist in evaluating gas or vapor monitoring appli-cations.

2.1 Combustible Gas and Explosive Limits

The primary risk associated with combustible gases and vapors is the possibility of explosions. Explosion,like fire, requires three elements: fuel, Oxygen, and an ignition source. Each combustible gas or vapor willignite only within a specific range of fuel/Oxygen mixtures. Too little or too much gas will not ignite—theseconditions are defined as the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL). Anyamount of gas between the two limits is explosive. It is important to note that each gas has its own LELand UEL, as shown in chart 1. The gas concentrations are shown by percent of total volume, with the bal-ance as normal air.

Chart 1 - Common Combustible Gas LEL’s and UEL’s

Between these two limits explosions can occur under some conditions, with the maximum explosive ener-gy available at approximately the midpoint. Note that these limits are sometimes referred to as LFL(LowerFlammable Limit) and UFL (Upper Flammable Limit). These limits are empirically determine, and variousauthorities sometimes quote slightly different figures, based on slightly different experimental procedures.

2.2 Why Is the LEL Important in Combustible Gas Detection?

In environments with combustible gas hazards, it is important to know long before the gas concentrationreaches the LEL. Typical safety standards require that a gas detection unit give warnings at 10 - 20% ofthe LEL. Do not confuse the alarm level with the volume of gas required to reach the LEL. For example:



7

Combustible Gas/Vapor LEL UELAcetone (CH3)2CO 2.15% 13.0%Benzene C6H6 1.2% 8.0%

Butadiene C4H6 1.1% 12.5%

Butane C4H10 1.5% 8.5%iso-Butane C4H10 1.8% 8.5%Ethane C2H6 3.0% 15.5%Ethyl Alcohol CH2H5OH 3.3% 19.0%Ethyl Ether (C2H5)2O 1.7% 36.0%Hexane C6H14 1.1% 7.5%Hydrogen H2 4.0% 75.6%Isopropyl Alcohol (IPA) (CH3)2CHOH 2.0% 12.7%Methane CH4 5.0% 15.0%Methyl Alcohol CH3OH 6.0% 36.0%

Methyl Ethyl Ketone MEK 1.8% 11.5%Pentane C5H12 1.5% 7.8%Propane C3H8 2.0% 9.5%Toluene C6H5CH3 1.2% 7.0%

Methane has an LEL of 5% by volume in air. For a gas detector to give an alarm at 10% of the LEL, it musttrigger when it detects 0.5% by volume. The detector for this application would most likely be calibratedfor the range from 0% to 5% gas by volume, but display the reading as 0 - 100% LEL.

2.3 Toxic Gas Threshold Limit Values

The primary risk associated with toxic gas is the possibility of poisoning, which can result in chronic healthproblems, disability, or death. The American Conference of Governmental and Industrial Hygienists(ACGIH) has gathered data on the physical effects of a wide range of toxic gases, and those data are usedto determine the Threshold Limit Values (TWA & STEL). The TWA is the concentration at which the gasbecomes harmful to human health over long term exposure (8-hour workday). The ACGIH has also stat-ed short-term exposure limits (STEL) for 15-minute periods for some gases. It is important to note thatthese values are different for each gas, and are expressed in parts per million (PPM), as shown in Chart2.

Chart 2 - Common Toxic Gas TLV’s

These TLV Values cannot be determined experimentally on humans, so they are deduced by long termexperience and tests on animals. The published values are under constant review and are subject tochange as further experience indicates. They generally are conservative.

2.4 Oxygen Deficiency

The primary risks in environments deficient in Oxygen are poor performance and judgment, physicalimpairment, unconsciousness, and death. The normal level of Oxygen in the atmosphere is 20.9% by vol-ume. Lower amounts of Oxygen cause progressively worse symptoms. Most safety authorities mandate aminimum safe Oxygen level of 19.5% by volume, providing a safe level of Oxygen if evacuation becomesnecessary.

2.5 Relationship Between ppm and % Volume

Gas and vapor levels are often given in terms of ppm (parts per million), or as % volume. Please note thefollowing physical relationship between these two:

1 ppm = .0001 % Volume10 ppm = .001 % Volume100 ppm = .01 % Volume1,000 ppm = .1 % Volume10,000 ppm = 1 % Volume100,000 ppm = 10 % Volume1,000,000 ppm = 100 % Volume

2.6 Flash Point

All liquids do not vaporize into gaseous form as readily as others. There are many flammable compoundsthat exist only in gas form at normal atmospheric temperatures and pressures. Some examples of theseare natural gas (Methane) or propane. If these gases are pressurized, they can be changed into their liq-uid state. Many other substances such as gasoline or other liquid fuels, or solvents, may be in liquid format normal atmospheric temperatures and pressures. These liquids will evaporate into a vapor if left in theopen air, and some will evaporate faster than others. The “Flash Point” is the temperature that is neces-sary for a given liquid to reach in order for it to evaporate sufficient vapor to cause a flammable concen-tration at atmospheric pressures. For example, gasoline has a relatively low flash point, which enables itto vaporize and explode in the engine cylinder. Diesel fuel, on the other hand, has a relatively high flashpoint (over 100 degrees F), so it will not produce combustible levels of vapor until it is heated above thistemperature. To emphasize this, imagine if you had a bucket of gasoline and a bucket of diesel fuel, bothat about 60 degrees F, and you measured the air space immediately above the liquid in the buckets withan LEL meter. The gasoline would cause a reading of over 100% LEL, indicating that if a match were lit inthis space, there likely would be an explosion. The diesel head space however, would likely read less than5% or 10% of the LEL, indicating that if a match were lit directly above this fuel it would not ignite.

It is important to consider the Flash Point when considering the potential hazard of a flammable liquid. Forexample, many jet fuels have a flash point of over 100 to 150 degrees F. If these liquids are spilled onto acold cement floor in cold weather, they may pose a danger from a ppm hydrocarbon breathing standpoint,but they will not pose any immediate flammable hazard (unless and until they are heated to temperaturesabove their Flash Point).

2.7 Vapor Density

Not all gases or vapors weigh the same as air. Every gas has a “Vapor Density” or just “Density” , whichis a physical constant of its weight in relationship to air. Therefore, air has a density of 1.0. Gases that arelighter than air have a density of less than 1.0, and gases that are heavier than air have a density greaterthan 1.0. Those lighter than air will tend to rise and those heavier than air will tend to sink or remain nearthe floor. The vapor density should be considered when evaluating sensor locations. For example, gaso-line and Propane have a vapor density greater than 1.0, indicating they are heavier than air. Sensors forthese gases should be located near the floor in order to provide the earliest warning of detection. On theother hand, Methane and Hydrogen have vapor densities less than 1.0, indicating they are lighter than air.Sensors for Methane and Hydrogen therefore should be located near the ceiling for best results.

2.8 Sample Draw vs. Diffusion

RKI offers both sample draw and diffusion sensors for many toxic gases. A diffusion sensor assembly is asensor that has its working surface open to the surrounding environment, and the gas migrates to the sen-sor by gaseous diffusion. A sample draw sensor has a pump or aspirator to draw the sample from the testspace and blow it into the sensor sample chamber. In general, it is better to use diffusion sensors for mon-itoring of room air conditions, and sample draw sensors whenever the test space is inside a duct or othernot easily accessible space.

Some manufacturers suggest the use of diffusion sensors even in duct mounting applications. RKI strong-ly recommends the use of only sample draw assemblies in these applications. Tests have proven that dif-fusion is not assure or as accurate as the use of a sample drawing sensor/transmitter, since the floweffects of the air blowing in the duct can greatly influence the output of the sensor. The diffusion sensorreading can be in excess of 60% low at lower flow rates for some gases. For a sample draw sensor / trans-mitter, the gas always blows onto the sensor at the same rate and direction as used during initial calibra-tion, providing superior accuracy and performance over a diffusion sensor. This situation is more pro-nounced for difficult-to-detect gases such as HCl, HF, and BCl3.

2.9 Sample Draw Tubing Lengths

When using a sample draw system, it is important to keep the sample lines as short as possible and touse proper tubing type. In general, for toxic gases, Teflon (PTFE) tubing must be used to avoid excessiveabsorption of the test sample into the tubing. Some gases are more easily absorbed than others.Recommended maximum tubing lengths for different gases are provided in the “Recommended TubingType and Lengths” chart on the following page. These lengths are intended to be guidelines and can beexceeded by short distances without much loss in reading. In general though, short sample lines will pro-vide readings that are more accurate and also provide faster response.

Tubing lengths: It is imperative that all sample tube lengths be kept as short as possible. This is importantbecause short tubes provide the fastest response time, and also because some gases become absorbedin the tubing and so cannot travel through long lengths. Monitors should be placed as close as possible tothe sample point so sample lines can be kept short as possible. Since some gases are more readilyabsorbed than others, we recommend the following as the maximum sample lengths:



10

Recommended Tubing Type and Lengths Chart

Filter Types:

Millipore: Gas types 1 and 2 above must use Millipore filter.

Balston: Gas types 3 and 4 above should use the Balston filter. Note that it is OK also for themto use the Millipore filter. These gases can use either one because there is not any worry aboutabsorption into the filter for these gases. It is recommended to use the Balston though since ithas more surface area and so will last longer if used in a dusty environment.

Note that filters are generally installed close to the instrument in an area that is accessible forfuture maintenance.

Tubing Material

3.1 Catalytic (for LEL level detection of flammable gases and vapors):

A catalytic combustion sensor is typically used in situations where detection of flammable gases or vaporsis required. The standard range of detection is 0-100% LEL, where “LEL” (Lower Explosive Level) is theminimum amount of the target gas or vapor that is needed to form a flammable condition in air. Catalyticcombustion sensors consist of two small coils of wire. One coil (the “active” coil) is treated with a catalystsuch as platinum or palladium, that help to initiate the burning reaction of flammable gases and vapors atconcentrations lower than would normally burn. The second coil is treated with a non-catalytic coating, andit operates as a “reference” to counteract for the effects of temperature and thermal conductivity that wouldotherwise cause the sensor to be less accurate. Both coils are heated by passing a current through them.When the hot active coil encounters even small concentrations of flammable gases or vapors, it causesthese to oxidize (burn). The heat of this combustion at the coil causes the temperature of the coil toincrease, which in turn causes the resistance of the wire to increase. The circuitry measures the resistancechange of the active coil, and interprets this signal as a measured amount of gas or vapor, based on thecalibration of the system.

The catalytic sensor generally can respond to practically all flammable gases or vapors, allowing it to becalibrated to represent the danger present in a wide variety of applications. Catalytic sensors should notbe used in applications where they will be exposed to known catalytic poisons such as Silicone vapors,lead vapors, chlorinated or fluorinated hydrocarbons, and to some degree, high or continuous H2S con-centrations.

Catalytic sensors require Oxygen to operate. Oxygen concentrations of 10% or higher are generally con-sidered necessary and sufficient to provide full LEL response on a catalytic sensor. However, significantLEL response can still be obtained for lower levels of combustibles (10% LEL) at levels even as low as2% Oxygen for some flammables.

3.2 Catalytic with molecular sieve (for Hydrogen specific LEL level detection):

RKI offers a very special Catalytic sensor for Hydrogen detection. This sensor is coated with a molecularsieve that significantly reduces the response from any other flammable gases or vapors. In particular, theresponse to IPA is practically eliminated. This sensor was developed for Semiconductor manufacturingapplications where Hydrogen is desired to be detected, but where IPA is often used as a cleaning agent.

3.3 Solid State (for ppm level detection of hydrocarbons):

Solid State sensors can be used for low level (ppm level) detection of many solvent vapors or gases. Atypical Solid State sensor consists of a heated element with a metal oxide coating. The metal oxide elec-trical resistance decreases when it comes in contact with certain gases, by the gases displacing Oxygenmolecules within the metal oxide. The amount of resistance change is greater when the target gas con-centration becomes greater. This type of sensor is not specific to any particular gas, but is a generalhydrocarbon sensor. It should only be used when the only gas present besides fresh air is the gas youwish to detect. It can also be useful as a general hydrocarbon leak detector, for storage facilities of a widevariety of solvents or chemicals. The ppm level detection ability of the solid state sensor can provide detec-tion of unsafe breathing levels of some solvents and gases, (as opposed to the much higher LEL levelsnormally detected by a catalytic sensor).

The Solid State sensor requires Oxygen in order to operate properly.

3.4 Solid State with molecular sieve (Hydrogen specific, 0-2000 ppm):

RKI offers a very special proprietary Solid State sensor for Hydrogen detection applications where even avery small leak needs to be detected. This sensor has a molecular Sieve coating on the sensing element,and this prevents any other gases from having an interference effect on the sensor. This sensor is typi-cally used to detect Hydrogen over a range of 0-2000 ppm, with no response caused by IPA or other gases



12

or solvents. This sensor does require an air background for proper operation. This Hydrogen ppm sensoris particularly useful in Semiconductor Fab applications, where is can reliably detect leaks 20 times small-er than a catalytic sensor.

3.5 Galvanic cell (for Oxygen detection):

The Galvanic Oxygen sensor is an electrochemical cell with a gel electrolyte and two electrodes. A mem-brane allows atmospheric contact with one electrode. Both electrodes are connected to an external meteror IC. Since normal atmosphere contains 20.9% Oxygen, a galvanic cell is always encountering Oxygen,and producing a voltage corresponding to the Oxygen level. An increase in Oxygen at the electrode caus-es increased electrochemical activity in the cell, producing a higher output voltage. Similarly, a decreasein the Oxygen that contacts the electrode will decrease the electrochemical activity, producing a lower out-put voltage. The output voltage is continuously measured, and voltage changes due to increases anddecreases in Oxygen can be used to switch relays or other alarms.

Galvanic Oxygen sensors require periodic calibration and replacement, due to consumption of the elec-trode or drying out of the electrolyte.

3.6 Electrochemical sensors (for ppm level detection of many toxic gases):

The Electrochemical sensor offers reliable, accurate detection of a wide variety of toxic gases. The sen-sor contains an electrolyte, and electrodes (Counter, working, and reference electrodes). The electrodesare connected to a power supply and supporting electronic amplifier. A gas permeable membrane allowsthe sampled atmosphere to enter the cell. Toxic gas in the sample causes an electrolytic chemical reac-tion, allowing current to flow between the working and counter electrodes. The current flow is proportion-al to the gas concentration, and is measured and interpreted by the supporting electronics to provide read-ings and alarms.

RKI offers many different electrochemical sensors for different gases. The chemistry of the sensor deter-mines what gases it will respond to, so different electrode materials and different electrolytes are utilizedto create a wide variety of sensor offerings. Although sensors can be highly sensitive to the target gas ortarget family of gases, they are not completely specific for an individual gas, so consideration must begiven to any other possible interfering gases that may be present in the test area or sample stream. Laterin this manual are provided typical "interference gas" charts to help determine the suitability of a sensorfor a particular application.

3.7 Ionization Chamber (for SiO2 and other particulate detection):

An Ionization Chamber can be used to detect the "presence" of some gases. An ionization chamber oper-ates similarly to a smoke detector, in that it detects the presence of smoke particles, and is not actuallymeasuring gas. Some gases like Silane will spontaneously combust when exposed to air in certain con-centrations. Although Silane gas can be detected with an Electrochemical sensor, if the concentration istoo high (above 15 to 20 ppm), it may spontaneously combust and there will be no actual gas left to detect.In this case, the Ionization Chamber method can be used to detect the smoke residue from the burning ofthe gas. In an ionization chamber, typically the sample is passed over a small radioactive source. Theradioactivity "ionizes" the particles, and the level of ionization is measured by a sensor which can be cal-ibrated to represent a known gas concentration. (For Silane detection, RKI offers a combination transmit-ter that has both an ionization chamber and an Electrochemical sensor, for sure detection of silanewhether it has burned or not).

3.8 Pyrolyzer with Electrochemical sensor (For ppm level detection of NF3, R-123, and others):

Some gases cannot be readily detected due to their chemical nature not being conducive to creating achemical reaction within an Electrochemical sensor. In some cases, if these gases are superheated, it will



13

chemically break down (or burn) the gas into smaller compounds or other constituents which may be morereadily detectable. A pyrolyzer is a heated chamber which the sample is passed through to be "pyrolyzed"or converted by the extreme heat. A pyrolyzer is not actually a detector, but is a sample conditioner, andit is used to treat the sample before it enters a detector. For NF3 detection, the pyrolyzer breaks down the

NF3 in air to form other compounds such as NO and NO2. RKI utilizes a pyrolyzer in conjunction with an

NO2 sensor for very reliable detection of NF3. This same method can be used for detection of certain

refrigerants such as R-123, which produces HF after being pyrolyzed, and the HF can be detected with anelectrochemical sensor.

3.9 Pyrolyzer with Ionization chamber (for ppm level detection of TEOS, TEOA, TMP, TMB):

Another combination detection technique is to use a pyrolyzer in conjunction with an Ionization chamber.Gases such as TEOS are not easily detected at low levels by other methods, but if the TEOS is passedthrough a hot pyrolyzer, it will burn and create SiO2 particulate, which is a smoke that can then be detect-

ed by an ionization chamber, as described above.

3.10 Infrared Sensor (NDIR):

Most gases will absorb infrared (IR) light over certain wavelengths. The wavelengths absorbed by a par-ticular gas, and the intensity of the absorption , are very distinct for each gas, sort of like a "fingerprint" forthe gas. An Infrared gas sensor makes use of this physical aspect of gases. An infrared sensor typicallyconsists of a chamber which the sample gas is passed through. At one end of the chamber there is an IRsource, which is a amp bulb or heater which produces IR energy. At the other end of the chamber is an IRdetector element. This IR detector measures the amount of IR energy that reaches it, and produces a sig-nal output proportional to the amount of this energy. Generally there is an IR filter in the IR path, whichallows the detector only to look at a particular wavelength region of IR energy. If gas which absorbs thisparticular wavelength or IR energy is present in the sample flowing through the detection chamber, it willreduce the amount of IR energy that reaches the detector. The measuring circuit compares this IR ener-gy to the energy that is present when fresh air is in the chamber (or when the IR source is turned off), andinterprets the signal and processes it as a measured reading of the detected gas.

3.11 Thermal Conductivity (for volume % detection of Methane or Hydrogen):

Every gas has a physical constant known as its "Thermal Conductivity” (or TC). This is a measure of theability of the gas to carry heat away from a hot object. Some gases, such as Hydrogen, have a greatcapacity for transferring heat, and so have a high thermal conductivity. If the thermal conductivity of a gasis different than that of air, either higher or lower, then this physical aspect of the gas can be used to detectit. A TC sensor consists of two small elements of wire that are heated by passing a current through them.One of the elements (the active) is placed in the gas stream, and the other (the reference) is sealed sothat the gas sample does not contact it. When the active comes in contact with a gas concentration thathas a TC that is different than air, it will cause the element to either cool down or heat up. This tempera-ture change of the element changes the electrical resistance of the element, which is then measured bythe supporting circuit and interpreted as a known gas reading.



14

3.12 Paper Tape Method:

A "Paper Tape" is a tape material that is impregnated with certain chemicals that sensitize it and cause itto change color when it becomes exposed to specific gases. The chemically treated paper tape is fedthrough a chamber where it is exposed to the sampled atmosphere. If the target gas is present in the sam-ple, it causes the tape to darken, or "stain". The tape is exposed to the sample for a specific amount oftime, and then the stain darkness is measured with a photocell. The stain darkness is proportional to thegas concentration present, and the photocell signal interprets this to provide a reading of the gas level.

RKI utilizes the paper tape method for detecting very low levels of certain gases. It can be highly specificfor the target gas, and can provide very low level, specific detection of certain gases that no other methodcan achieve. The paper tape method is used in our models FP-250 and FP-260 series instruments fordetection of many toxics including many metallo-organics, Formaldehyde, H2S, Hydrazine, Phosgene,

and many semiconductor gases.

In a paper tape machine, the tape is automatically advanced periodically, so that the gas sample can beexposed to a new section of tape. Tape cassettes generally hold enough tape to last about 30 days.

4.1 List of Detectable Gases

The following is a partial list of gases which RKI Instruments can provide detectors for. Please keep in mindthis is only a partial list, so if you do not see the particular gas or vapor that you need detected, pleasecontact RKI for assistance in selecting the proper sensor type.

There are some terms used on this list that may need explanation. Please note the following:

4.1.1 LDLThe Term “LDL” means “Lower Detectable Limit”. This is the lowest concentration that the sensorcan reasonably and reliably detect.

4.1.2 TLV / TWAOn the TLV/TWA column for some gases the chart lists HCL, HF, or NO2 before the gas concen-tration. This means that the target gas is converted to HCL, HF, or NO2 in order to be detected.Some gases are very unstable in air, and they will spontaneously convert to another gas such as HCL or HF upon contact with air and moisture. In these cases then, the presence of the targetgas can be detected by the presence of the gas it has been converted to.

4.2 Components of a Gas Monitoring System:

A gas monitoring system consists of 3 parts: the sensor, transmitter, and controller.

4.2.1 Sensor

The sensor is the actual device that is sensing the gas. Many sensor types are described in theprevious section on “Sensing Technologies Offered by RKI” of this manual. Sensors typically last2 to 4 years, but can last longer or shorter time depending on the nature of the application. SolidState sensors, and Infrared sensors, typically last much longer and it is not uncommon for themto last for 5 to 10 years or more.

4.2.2 Transmitter

Most sensors require a transmitter to amplify the sensor signal, and to convert the gas sensor sig-nals into a standardized output, such as 4-20 mA, for transmitting the signal to a controller. The transmitter is usually in close proximity to the sensor, and zero and span adjustments must bedone at the transmitter. Note that some sensors and controllers do not require the use of a trans-mitter for LEL or Oxygen detection (Beacon 100, Pioneer, RM-580), and also one is not neededfor short distance wiring of H2S or CO sensors for the Beacon 100. All RKI transmitters are oper-ated from 24 VDC, and utilize either 2 or 3 wires. In general, even if a sensor can be used with-out a transmitter, use of a transmitter is often preferred for distances over 300’ to 500’ to simplifythe calibration effort. In general, even if a sensor can be used without a transmitter, use of atransmitter is often preferred for distances of 300’ to 500’ to simplify the calibration effort.

4.2.3 Controller

The controller is the device that receives and interprets the signals from the sensors and/or sen-sor/transmitters. The controller typically provides a readout of the gas concentration, audible andvisual alarms for dangerous gas levels, and generally alarm relays for activating an external alarmor other action. RKI has a wide variety of controllers available. We have them for just one sensor,4 sensors, 8 sensors, and rack or wall mounting systems for 12 to 16 sensors. Additional con-trollers can be added to provide hundreds of points of detection.

In some applications it is preferred to send the transmitter signal (such as 4-20 mA) directly into aPLC (Programmable Logic Controller) or other similar control device. In this case, the alarm con-ditions and relays are activated by the PLC and the use of a “Gas Detection” controller suppliedby RKI is not necessary.

Note: RKI offers a category of instruments called “Stand Alone” units. This is a single point gas monitor thatincludes the sensor and transmitter or sensor and controller in one enclosure.(In this case no additional transmit -ter is needed). This typically also has a readout of the gas concentration and the sensor/controllers also includealarm(s) with relays. Use of this type of unit is very convenient in situations where only one gas and one locationneeds to be monitored, since wiring and installation costs are reduced. This style also has a 4-20 mAor other out -put, so that it can be connected to a controller or PLC, if desired.

The GD-K8A is a diffusion assembly for electrochemical sensor detection of toxic gases.There are many different sensors that can be used in this assembly, making it useful fora wide range of toxic gas detection applications. The electrochemical sensors used typi-



20

cally have lives of 2 to 4 years or more, and can be calibrated at 6 month intervals. Thesensor signals are converted to a 4-20 mAsignal for transmission to a controller (24 VDC,2 wire loop). The housing of the GD-K8A is an indoor metal enclosure with a hinged door,and is not appropriate for outdoor use or for corrosive environments. Please refer to theback of the GD-K7D2 brochure in this manual to see the list of gases that this assy canbe supplied to detect.

The GD-K8A4X is similar to the GD-K8A listed above, except it is repackaged into aNEMA 4X enclosure for use in wet or corrosive environments.

4.3.1.7 GD-K7D2

The GD-K7D2 is RKI’s workhorse sample draw assembly for use with a wide variety ofElectrochemical sensors for toxic gas detection. It is designed for simple servicing in thatthe sensor and pump can be easily replaced in less than one minute each. The GD-K7Dis normally supplied with a 115 VAC pump, which requires local AC power, and the sen-sor signal output is 4-20 mA(24 VDC, 2 wire loop). An optional 24 VDC pump is available.Please refer to the back of the GD-K7D2 brochure in section H4 to see the list of gasesthat this assy can be supplied to detect.

4.3.1.8 GD-K8DG, GD-S8DG (Pyrolyzer assemblies)

The GD-K8DG is a special sample drawing sensor/transmitter assy that has a pyrolyzerto condition the sample. This device is typically used for detection of NF3, where thepyrolyzer breaks down the NF3 into smaller chemical constituents, and then detects it withan electrochemical sensor as NO2. This is the most reliable method available to detectNF3. This assembly requires 115 VAC local power to power the pump and pyrolyzer (24VDC version also available). The sensor signal is converted to a 2 wire 4-20 mA signal.

The GD-S8DG is another special sample drawing sensor/transmitter assy that has apyrolyzer to condition the sample. This device is typically used for detection of TEOS,TEOA, TMB and TMP, where the pyrolyzer actually burns the target gas and converts itinto Si02 particulate (smoke), and the SiO2 is then detected with an ionization chamber.This is the most reliable method available to detect certain gases, and can achieve lowerlevels of detection with fewer interferences than most other methods. This assemblyrequires 115 VAC local power to power the pump and pyrolyzer (24 VDC version alsoavailable). The sensor signal is converted to a 2 wire 4-20 mA signal.

4.3.1.9 Model 35-3000RK(A) sample draw

The Model 35-3000RK is a sample draw assembly for LEL or Oxygen, packaged in aNEMA 4X enclosure. It contains an internal 24 VDC pump, and has a flowmeter visiblethrough the hinged front door. This assembly can be supplied with direct connection LELand Oxygen sensors, for use with the Beacon 100, and the Pioneer series. Those moni-tors provide a 24 VDC output connection to power the pump.

Model 35-3000RKA is similar to the non “A” version described above, except the “A” ver-sion is supplied with a 4-20 mA transmitter. This assembly can be provided with LEL,Oxygen, H2S, or CO sensors.

4.3.1.10 Explosionproof Sample draw, Models GD-D8, GD-D8V

For explosionproof applications where a sample draw system must be used, RKI offersthe GD-D8 series of sensor heads. These assemblies contain a 115VAC pump for con-tinuous sample draw, and the pump and sensor are contained within an explosionproof



21

enclosure. These assemblies do not have remote transmitter ability, but only work fordirect connection sensors. The following versions are available:

GD-D8 : This assembly is used for LELdetection and comes with an internal catalytic sen-sor. This can be either a general purpose hydrocarbon LEL sensor, or it can be aHydrogen specific catalytic sensor.

GD-D8V : This assembly is used for ppm detection and comes with an internal solid statesensor. This can be either a general purpose hydrocarbon ppm sensor, or it can be aHydrogen specific solid state sensor.

4.3.2 “Stand Alone” Units :

RKI offers a number of “Stand Alone” units. These instruments are complete monitors containingsensors, transmitters, readouts, signal output (typically 4-20 mA), and sometimes also alarm lev-els with relays. These transmitters can be used by themselves with no additional equipment need-ed, or they may be used for local readout and control but still be connected to a central controlleror PLC.

4.3.2.1 Eclipse for LEL, H2S, CO, Oxygen

The Eclipse is a “Smart” sensor/transmitter assy that can be used for LEL, Oxygen, H2S,or CO detection (one gas per Eclipse unit). It uses the 4 basic sensors listed first in items1 through 4 above. It is housed in an explosionproof junction box, and its electronicssends a 4-20 mA signal to a controller or PLC. The Eclipse has a readout so the user canview the gas levels at the transmitter. It also has “NIC” capability (Non IntrusiveCalibration”), which means that it can be calibrated from the outside without the need toopen up the housing. Using a Patent Pending technology, the Eclipse utilizes a light sen-sor for zero and span access. No tools are required. This Model is especially useful in haz-ardous locations due to its simple “Non Intrusive” calibration process. Note that theEclipse does NOT have alarm levels or relays.

4.3.2.2 GD-K11D, GD-V11D

The GD-K11D is a self-contained sample drawing gas monitor that utilizes variousElectrochemical sensors for detection of a wide variety of toxic gases. The instrument con-tains special circuitry and software that automatically counteracts for all reasonable sen-sor or electronics drift, preventing false alarms caused by drift. Designed so that the sen-sor and pump can be changed out in less than one minute each, this instrument isextremely reliable and easy to maintain. Long life sensors operate for 2 to 4 years or more,and 6 months is typical between calibrations. This instrument is intended for indoor useand is housed in an indoor metal housing with a hinged door. The GD-K11D has a digitalreadout of gas concentration, and it contains one adjustable alarm level with relay. It hasa variety of signal outputs available, including 4-20 mA, twisted pair communications (RS-485/232) between many units, and Lonworks tm Spread Spectrum transmission on the ACpower line.

The GD-V11D is for Hydrogen specific detection. It has all the features mentioned justabove for the GD-K11D, except that it does not use an electrochemical sensor, but insteaduses the 0-2000 ppm Hydrogen specific solid state sensor with molecular sieve.

4.3.2.3 GD-K11DG, GD-S11DG

These instruments have all the features of the GD-K11D series listed above, except theyalso utilize a pyrolyzer heater unit for detection of specific gases as follows:



22

The GD-K11DG-NF3 is used is used for detection of NF3. It contains a pyrolyzer and anelectrochemical sensor.

The GD-S11DG can be used for TEOS, TEOA, TMB, and TMP detection. It uses apyrolyzer and an ionization chamber for detection of these compounds.

4.3.2.4 GD-K77D

The GD-K77D is similar to the GD-K11D above, except it is the next generation. It ishoused in a narrow profile metal housing for minimum use of wall space (indoor use only).It too is designed so that sensor or pump can be changed in less than one minute. It alsohas additional sensor intelligence such that the sensor can be calibrated separately fromthe unit, and then plugged into the unit and have the unit read the calibration back andadjust itself. Signal outputs are the same as on the GD-K11D.

4.3.2.5 FP-250A, FP-250FL, and FP-260 Paper tape machines

RKI offers 3 paper tape machines that can be used for detection of special gases or atlevels not easily achievable by some other detection method. The paper tape machinesare all sample draw type, and utilize a paper tape cassette that must be replaced every30 days. These instruments have a readout of gas concentration, an alarm with relay andaudible alarm, and a 4-20 mA output of the gas concentration. The tape is read on a cycli-cal basis, and the reading is then updated at the end of each cycle. The cycle lengthdepends on the gas and range being monitored, but is typically 30 to 60 seconds.Thisinstrument can be used for a wide variety of toxic and metallo-organic gases; please seethe backs of their brochures for some of the available gases and ranges. These instru-ments are considered as “semiportables”. They are benchtop type monitors that must beplugged into 115 VAC for operation, but they are lightweight enough so that they can beunplugged and carried to another location if desired. They are designed for continuoususe. The differences among the 3 available versions are as follows:

The FP-250A is the original design and it has a wider variety of tapes available for it, so ithas a wider selection of gases available. The tape access is on the side of the unit.

The FP-250FL is a special version intended for detection of formaldehyde only. It is uniqueand is one of the few methods available for accurate low level specific detection offormaldehyde. The detection cycle is 15 minutes.

The FP-260 is a newer design and it utilizes a lower cost cassette tape than the FP-250A.The FP-260 tape is similar to a VCR tape, and it loads from the top, making it easier topermanently mount into a cabinet if desired.

4.3.2.6 RI-255 refrigerant monitor

The RI-255 contains a sample drawing Infrared sensor for use to detect refrigerants, nor-mally over a range of 0-5000 ppm. It is housed in an indoor use wall mounting metalenclosure, and it operates from 115 VAC. It has a digital readout of gas concentration, anadjustable audible alarm, and an alarm relay. It also has a 4-20 mA output if it is desiredto connect it to a central controller or PLC.

4.3.2.7 Model PS2

The Model PS2 is a low cost monitor for simple applications of gas or vapor monitoring.It does not have a readout, and it does not have a 4-20 mA output, so it cannot be tied



23

into a central controller. The PS2 is a self contained go/no-go type monitor, which can beset to alarm if particular gas levels are exceeded. It has an audible alarm, and 2 alarmrelays. It is housed in a plastic wall mounting indoor enclosure, and operates from either115 VAC or 24 VDC. The sensor is prewired to the PS2 on a 30 foot cable. The sensor isnot considered explosionproof so should not be considered for use in a hazardous area.Two different sensors are available; one for LEL levels and one for ppm levels of hydro-carbons or solvent vapors.

The sensor used in the PS2 is a non-specific solid state sensor. It will respond to manydifferent gases and vapors and should only be used where the only gas present besidesfresh air is the gas you wish to detect. The PS2 is most appropriate and a great low costsolution for monitoring of Hydrogen levels in battery storage areas, and for detection ofsafe breathing levels of solvent vapors in workspaces or storage areas.

4.3.3 Controllers :

RKI offers a wide variety of controllers for readout and alarming of the gas detection signals. Thisincludes single channel controllers and multipoint controllers to handle any number of points. Toselect the best controller for your application, you should consider the number of detection pointsneeded, the type of sensors desired, and the distances between sensors. Some applicationsrequire the gas signals to all be readable from a single controller location. In other cases it mightbe better to utilize more than one controller, located in different parts of a building, to help reducewiring and installation costs. A brief description of each controller is provided below. For moredetailed information on each controller, please see the controller detail section of this manual.

4.3.3.1 Beacon 100:

This is a simple but very flexible low cost controller for use when just one sensor (one gas)needs to be detected. It is in a wall mounting NEMA 4X housing. The sensor can be con-nected either directly at the controller or it may be wired remotely. Sensors for LEL,Oxygen, H2S, or CO may be wired directly to the controller, or any of RKI’s many 4-20 mAsignal input sensor/transmitters can be connected. The Beacon 100 has 3 adjustablealarm levels with relays, plus a fail or malfunction relay.

4.3.3.2 Beacon 800:

This is a powerful, compact, user friendly controller that can handle up to 8 channels of 4-20 mAsignal input. Each channel has two alarm levels with dedicated relays, and there isalso a common set of relays for alarm and fail. It has options available such as heavy dutyrelays (30 Amps) for fan control, and individual signal outputs (4-20 mA or 1-5 VDC). TheBeacon 800 is an excellent controller to use anytime 3 to 8 points of detection are need-ed, and it is especially well suited for CO monitoring in parking garages.

4.3.3.3 Pioneer-4W

The Pioneer-4W is a versatile NEMA 4X wall mounting controller that will handle up to 4points of detection. It can accept sensors for LEL or Oxygen wired directly, and all othergases must use a 4-20 mA transmitter. Each active channel utilizes a plug-in analyzercard. This card has terminals for all the wiring connections associated with that channel.The same card is used no matter what gas is being detected. Each channel has 3 alarmlevels with relays, plus there are common relays for the 3 alarm levels and fail. ThePioneer-4W is very flexible and is a good choice when 2, 3, or 4 points of detection areneeded.



24

4.3.3.4 Pioneer-16R

The Pioneer is also available in a 16 channel rack mounting version. Installing in a 19”Electronics rack, and measuring just 7” high, it can handle a lot of channels in a smallspace. It uses the same plug-in analyzer card as described above for the Pioneer-4W. Itcan accept sensors for LEL and Oxygen directly wired without the use of a 4-20 mA trans-mitter, or it can accept any 4-20 mA transmitter.

4.3.3.5 RM-580 Modules

The Model RM-580 series consists of plug-in analyzer cards and a housing to plug theminto. (The housings are called Model 570 controllers, and they are described directlybelow). The RM-580 analyzer cards each handle one sensor, and different cards exist fordifferent styles of sensor input. All cards have a brilliant 3 color LED readout that can eas-ily be read and understood from across a room. Each channel has two alarm levels withrelays. LEL sensors, Oxygen sensors, and ppm Hydrocarbon or Hydrogen (Solid State)sensors can be directly wired to the RM-580 controller; all other gases utilize a 4-20 mAtransmitter.

4.3.3.6 Model RM-570 housings for RM-580 modules

There are many different sizes and styles of housings available for the RM-580 cards. Thehousings contain the power supply and all the terminal connections. Versions that haveprovision for more than one plug-in analyzer card also contain a separate plug in cardcalled the TAN-580, which has a common buzzer, reset switch, and alarm relay terminals.The housing options are as follows:

RM-570-W : Various sizes of wall mounting enclosures are available, to handle up to 4, 6,9, or 12 channels (sensors). These sheet metal enclosures are intended for indoor use.Each active channel must have one RM-580 analyzer card plugged into it. Power is 115VAC or optionally 24 VDC.

RM-570-12R : Also available is a rack mounting controller housing for the Model RM-580.This housing installs into a standard 19” electronics rack, and can handle up to 12 chan-nels of gas detection. Power is 115 VAC.

570-SR : For applications where just one point of gas detection is needed, we offer a com-pact panel mounting single channel case. This is ideal for installation into process equip-ment. Please note that a separate reset button must be utilized if latching alarms aredesired, and 24 VDC power must be supplied to the enclosure to power the module.Wiring terminals are provided on the rear of the enclosure.

570-TM : For open chassis installations, the TM-570 can be used. This is a surface mount-ing holder for 1 analyzer card. It requires 24 VDC for power, and a separately mountedreset button if latching alarms are desired. Wiring terminals are provided on the front ofthe base of the unit.

4.3.3.7 BL-7000, 16 channel controller

The Model BL-7000 is a wall mounting controller capable of handling up to 16 sensorinputs. It can accept the same sensor inputs as the Model RM-580, which is that LEL sen-sors, Oxygen sensors, and ppm Hydrocarbon or Hydrogen (Solid State) sensors can bedirectly wired to the BL-7000 controller; all other gases utilize a 4-20 mA transmitter. TheBL-7000 has a large color touch panel screen for displaying the status in several different



ways. It also can provide a history exposure graph display of the past 8 hours; a very use-ful feature for analysis in an alarm situation. The BL-7000 utilizes 4 separate plug-in cardsthat handle up to 4 sensors each. Sensors connected to a card must all be of the sametechnology, (such as 4 electrochemical, 4 catalytic, 4 solid state, etc.). Card types can beeither all the same or mixed in the same BL-7000. Cards do not need to be ordered sep-arately, but the desired types must be specified when ordering. The BL-7000 can beordered with either one or two relays per channel.

4.3.3.8 Self Contained, or “Stand Alone” Controllers

RKI offers several “Stand Alone” controllers, which handle just one sensor and the sensoris included inside the instrument. These instruments are already described in the previoussection on “Stand Alone Controller/Transmitters”. These instruments are often good choic-es for applications where just one point of detection is needed.

4.4 Approvals

In some applications it is necessary to have certain "Approvals" or "Classifications" in order to satisfy cer-tain jurisdiction requirements from fire departments, local governments, etc. Typically, the requirement willbe to have the equipment certified by an independent third party that it satisfies certain electrical safetydesign criteria, or that it is suitable for use in the intended environment. Examples of approval agenciesare CSA, UL, or FM. There are many other recognized agencies also, and typically they test to the crite-ria stipulated by one of these 3 agencies. Not all applications require approvals, but for the ones that doit is important to consider what approvals are needed and to select equipment that has these approvals.

Some of the RKI equipment has certain approvals. At the time of this writing many additional RKI con-trollers and sensor/transmitters are undergoing testing by a third party to the CSA and UL standards. Ifyour application requires approvals, please check with RKI for confirmation of which equipment has com-pleted the approvals, and for assistance in selecting the proper equipment.

8.1 Wiring Guidelines for RKI Fixed Controllers and for Sensor or Sensor/Transmitter Connections

The following guidelines represent the conductor quantities and minimum wire sizes that should be usedfor wiring sensors or sensor/transmitters to the RKI fixed controllers for gas detection. Please note the fol-lowing:

8.1.1 Use either the sizes listed below or larger (never smaller).

8.1.2 Wiring cables should either be shielded or be installed inside a conduit.

8.1.3 All 4-20 mA signal wiring must use shielded twisted pair signal cables.

8.1.4 Please note that for assemblies with 115 VAC required for the pump, it is assumed that AC powerwill be obtained locally, and these wires are not counted in the column 2 wire count.

8.1.5 For assemblies with 24 VDC pumps, it is assumed that the pump power will be obtained from thecontroller, and so these wires (2) are included in column 2 wire count.

9.1 Air Aspirated Sample draw , Part number 30-0951RK (for LEL or ppm Hydrocarbons, or ppm H2)

RKI offers an air aspirated sample draw that can be used with our 1/2” NPT style sensors (available forLEL or ppm hydrocarbons, or ppm H2 detection). This assembly can be used when the gas stream to bemonitored is wet or has the likelihood of condensation forming in the sample line. The air aspirator requiresa compressed air source (10 to 300 PSI), and it utilizes an air driven aspirator pump to draw sample intothe detection chamber. If liquid is drawn into the chamber, it is sucked out through the aspirator and so itcannot accumulate in the chamber. This assembly consists of a sensor chamber, air aspirator, pressureregulator, and flowmeter. Tube fittings are provided for connection of the sample inlet, compressed air inlet,and exhaust. Note that sensor and junction box must be purchased separately.

9.2 J-Tube assy for wet samples, Part number 33-0401RK

A J-tube is a tube shaped like a “J” that can be used in conjunction with a self draining moisture trap(included) to provide continuous self draining of a sample line. The bottom of the “J” remains filled with liq-uid which prevents air from being sucked through the “J” and into the gas monitor. This is a useful acces-sory to use with sample draw systems where the samples will contain moisture or condensation. The J-Tube assembly must be used in conjunction with a self draining bowl type moisture trap, which is includ-ed along with the J-Tube assembly as part of part #33-0401RK.

9.3 Standby battery / charger assembly, Part number 49-8101RK

RKI offers a standby battery assembly for connection to controllers which accept a 12 VDC input. Thisassembly is housed in a NEMA-4X plastic wall mounting enclosure. It is powered by 115 VAC, and con-tains a trickle charger and a 12 AMP - hour gel cell battery. This will provide approximately 4 to 20 hoursof standby operation, depending on which system it is connected to and what sensors are utilized.Terminals are provided for 115 VAC input wiring and for 12 VDC output wiring.

10.1 Description and Explanation of Importance:

The Applications Work sheet is a guide which compiles all of the information normally necessary to con-sider to select and design a gas monitoring system. The Work sheet questions will help define the appli-cation parameters so that the pertinent considerations can be included. Please take care to fill out theApplications Work sheet completely and accurately. Feel free to contact RKI if you need assistance orhave any questions regarding the work sheet or how to consider the information on it. When contactingRKI for assistance, please first fill out the work sheet as much as you can and Fax it to RKI at (510) 441-5650 prior to calling so that the RKI Systems Applications Engineers can best serve you.

10.2 How to fill out Applications Work sheet:

Please make a copy of the Applications Worksheets in this manual, and return the originals to the binderfor later use. The work sheet consists of 4 parts:

10.2.1 Customer information, description of the general application, and what gases and ranges youneed to detect. Please fill this information in carefully since it is critical in helping to select the prop-er system.

10.2.2 Conditions at the sensor location. Please describe the environmental conditions at the sensinglocation. The work sheet asks questions and has blanks to fill in the appropriate information.

Sketch:(Please include rough dimensions, note significant features and equipment, suggested sampling sites, etc.)


This section describes the steps to follow to evaluate a gas monitoring application, and to select the best systemfor the application. The first 4 steps pertain to filling out the applications survey sheets. The remaining steps assistyou in evaluating the information, making the equipment selection, and considering any other options or equipmentthat you may need.

11.1 Define the problem: Which gases need to be detected and at what range?

List the gas or gases that you need to detect (the “target” gas or gases), and over what ranges you needto detect them. What is the reason for detecting these gases? Is it to prevent explosion? To preventasphyxiation? To prevent employee exposure to potentially toxic gases or vapors? To control a process?At what gas levels do you wish to take action, and what is the action that needs to be taken?

11.2 Define the area to be monitored:

The area to be monitored must be examined carefully and the questions on the applications survey mustbe carefully considered and answered. This will assist you and RKI Systems Applications Engineers tomake the most informed selection of the proper equipment to solve your gas monitoring application. Whatis the classification of the area? Do the sensors need to be explosionproof? Intrinsically safe? Weatherresistant? Corrosion resistant?

11.3 Define the area the controller will be installed, and what action the controller must take:

The site where the controller will be installed must be carefully considered, and the questions regardingthis area answered on the applications survey. Also consider what action or information you will expect thecontroller to provide to you, if any, and if you might possibly need to expand the system in the future. Thiswill help you and RKI to select the most appropriate controller for your needs.

11.4 How to determine the quantity of sensors needed and sensor placement:

Please consider the guidelines below, and draw your proposed sensor locations on the Applications Work sheet sketch graph paper. Fax it to RKI for review or assistance.

11.4.1 How much area can one sensor cover?

Consider that a sensor operates similarly to a person’s nose. A nose can only sense what isimmediately surrounding it. If there is a skunk 10 feet away, but with a strong wind blowing thesmell away from you, you may not smell the skunk, or at least not smell it very strongly. On theother hand, if you are downwind of the skunk, even 100 feet away, you likely will smell it. If youare indoors with the skunk, the vapors can travel quite a distance to cover the entire room.Depending on ventilation patterns, the smell may be worse in some areas than others.

Gases behave much the same as the skunk odor. The key is to locate the sensors as close aspractical to the likely leak source or sources. If the gas could come from almost anywhere in abuilding, such as for CO monitoring in a parking garage, then it is necessary to spread sensorsaround the entire garage to get full coverage. In another example, if you are monitoring a 100’ by100’ room for flammables, but the only possible source of flammables is a tank in one corner, thenit is necessary to monitor the tank in the corner but not necessarily other areas of the room.

11.4.2 Sensor spacing for indoor applications

For applications where the gases could exist anywhere in the facility, a decision must be madehow far apart to place the sensors and how many sensors should be used. There is no fixedanswer to this that is correct for all applications, but an industry guideline is to space the sensorsapproximately 40 to 50 feet apart for indoor applications. Your decision must be based on your

11.0 Steps To Selecting A Gas Detection System


36

careful evaluation of the hazard from the gases, and an assessment of the ventilation patternsinside the facility. Practicality and cost must also be considered. For example, if monitoring a 1mile tunnel for CO levels, it would probably be considered excessive to place sensors every 50feet, and a much wider spacing would likely be used. For typical indoor applications though, the40 to 50 foot guideline is a good starting point. If spacing the sensors 50 feet apart, then you wouldalso space the sensors 25 feet away from the wall. Using the sketch of the area to be monitoredin the Applications Work sheet, mark the proposed sensor locations by spacing them an appro-priate amount apart.

11.4.3 Sensor spacing for outdoor applications

Outdoor applications will be very susceptible to wind conditions, and good coverage of a pointsource leak, such as a propane tank or valves, cannot be done with just one sensor. If the tank orvalves cannot be enclosed or shrouded somehow, then sensors should be placed as close aspractical to the possible leak source, and multiple sensors should be used to provide good cover-age for all typical wind directions. If monitoring a valve jungle, for example, it may be possible toplace a shroud covering the valves, and then monitor inside the shroud with just one sensor. Theshroud will help to shield the vapors from the wind and help to contain them for detection.

In open air monitoring outdoors where the vapors could be coming from many sources or direc-tions, such as a refinery, then the decision of how many sensors are needed can be made simi-larly to the indoor guidelines given above, except that a closer spacing of 30 to 40 feet betweensensors is recommended. In all cases, sensor count can be reduced if the possible leak sourcesare known and the sensors can be concentrated closer to the leaks.

11.4.4 Other considerations or guidelines

In deciding sensor count and location, please consider the following:

11.4.4.1 Locate sensors strategically so they will be in the most likely path of a gas leak. Carefullyevaluate possible leak sources and ventilation flow of the area to be monitored.

11.4.4.2 Consider the density of the gas. Gases that are lighter than air will rise, so sensors forthese should be located near the ceiling . Heavier than air gases or vapors will tend toremain near the floor so sensors for these should be located near the floor.

11.4.4.3 Flash Point : Consider that flammable substances with high flash points (higher than typ-ical normal room temperature of 60 to 70 degrees F) will not have much vapor present ifthe surrounding area is cold. Liquids with high flash points are not capable of producing aflammable level of vapor at cold temperatures, unless the liquid is heated. Sensors mustbe located as close as possible to the leak source of these liquids in order to detect them.

11.4.4.4 Temperature: Consider the temperature of the area to be monitored. Gas detection sen-sors have certain temperature limits that cannot be exceeded. If the area is too hot for thesensor, you should consider using a sample drawing type sensor to allow the sample tocool before being exposed to the sensor. If the hot vapors being monitored have a flashpoint temperature higher than the ambient conditions, then the sample cannot be cooledbelow this or condensation of the vapors will occur in the sample tubing. In this sort ofapplication, please consult the factory for another solution such as a heated samplingsystem or other device.

11.4.4.5 Wet areas: If the area is wet, please take care to select sensors (and controllers) that areintended for wet areas. Install sensors facing downward so they can shed the water orrain. If using a sample draw system, install appropriate water traps or hydrophobic filters.If possible, install detectors where exposure to splashing will be minimized.



37

If monitoring a trench that could periodically get filled with water, mount the detector highenough in the trench so that it cannot get flooded. If this is not possible, consider use ofa sample draw head with a floating sample inlet.

11.4.4.6 Vibration: Install detectors where they will be free from vibration. Heavy or constant vibra-tion can shorten the life of a sensor.

11.4.4.7 Dust or dirty areas: If area to be monitored is especially dirty or dusty, select sensors orfilters that will prevent the dust or dirt from clogging the sensor. Consult RKI for assistancewith these areas.

11.4.4.8 Maintenance: When selecting sensor locations, keep in mind that sensors must be acces-sible for maintenance. Do not install in difficult to reach areas. If this is not possible, thenconsider use of a sample draw detector head, so that the sample tube only is run to theinaccessible area, and the sensor can be located in an easy access location.

11.4.4.9 For location of toxic gas sensors to protect workers, consider the location of the workersin relation to the source of the toxic gases. Locate the sensors between these two to pro-vide an early warning of rising gas levels.

11.4.4.10 Physical protection: Do not install sensors where they may be physically hit or abused,blocked by mud or other debris, painted over, or subject to steam or hosing down.

11.5 Define what type of system is needed :

Using the information provided in Sections 1 through 4 above on the applications survey, you are nowready to define what type of system is needed. Most of the definition will be obvious from the applicationssurvey. You now must define the following:

11.5.1 Sensor / Transmitter Questions:How many sensors are needed for each gas type?Sample draw or diffusion sensors? Is sample conditioning necessary, and if so what type of conditioning?Select the most appropriate sensor technology.Is a local readout or local relays a requirement?Are non intrusive calibration heads a requirement?

11.5.2 Controller Questions:Is a central controller necessary?Wall mounting or rack mounting controller? How many alarm points are needed? Are relays needed for the alarm points? If so what amperage is needed?What action is intended to take place if an alarm occurs and how will that action happen?

11.6 How to select the proper system for your use:

Now that you have defined the number of points, the sensor and controller locations, and what the systemneeds to do, you can select the proper sensors and controller for your application.

11.6.1 Select the proper sensor/transmitter type from the RKI Product Overview section of this manual.Select by gas type, and by environmental conditions (for example whether the sensor needs to beexplosionproof or not). If you cannot find one that suits your needs, please contact RKI for assis-tance.

11.6.2 Once you have determined how many detection points are required, you can select the appropri-ate controller for your use. Select the controller from the RKI Product Overview of this manual, orfrom the “Product Selection Chart” at the end of this section. If you are anticipating expansion inthe future, you may want to select a controller that has capability of adding a few points. Otherthings to consider are the number and location of the controllers. For example, if you need 8 pointsof detection, but their locations are spread throughout the plant, you might wish to consider usingtwo 4 point controllers located at different ends of the plant to save on wiring costs. (If you needall the readouts at one location, then you would not consider two four point controllers).

Another thing to consider in selecting the controller is what action is required from the controller.If you need alarm levels, relays, or 4-20 mAoutput terminals, then select a controller that providesthese functions.

Finally, consider the environmental conditions at the controller location(s). Select a controller thatmeets these conditions.

11.6.3 Discuss application with RKI: Consult RKI Applications Engineering to review the application andthe sensor and controller selection.

11.7 Product Selection charts

As a useful guide to help you select the most appropriate system for your use, this section includes selec-tion charts describing the appropriate controller possibilities based on the number of sensors needed.

To use the following charts, first decide how many sensors are needed, considering possible future expan-sion, and then turn to the selection chart for that number of sensing heads. The charts provide a con-densed description of features for each unit, to aid you in selecting the one which best suits your applica-tion

11.8 Other considerations:Are there any special conditions or additional equipment that need to be care of? Please consider thesenow. Some examples of this may be the following:

11.8.1 Calibration Kit:

It is recommended that all systems be calibrated when first installed, and then at a minimum of 3to 6 month intervals thereafter. RKI can supply a calibration kit for most systems. A calibration kitnormally consists of cylinder(s) of appropriate calibration gas, a valve or regulator, tubing, and atest cup to apply the gas to the sensor. It is generally recommended that you purchase a calibra-tion kit with your system. Since there are numerous combinations of systems and gases, pleaseconsult RKI for selection of the appropriate Calibration Kit for your use.

11.8.2 Battery Backup:

Some critical applications require a battery backup system, or a UPS (Uninterruptible PowerSupply) for their gas monitor. If you need this, it can be provided by RKI or it can be purchasedfrom some other source. UPS systems for computers are readily available from many sources andare reasonably priced. RKI offers a battery backup (12 Amp Hours) in a NEMA 4X enclosure thatcan also be used. Battery backups are generally connected to the 12VDC or 24 VDC input powerterminals on the controllers. A UPS system is normally connected to the 115 VAC terminals on thecontroller. In either case, the backup power automatically takes over should the primary power failto the unit.

If you need backup power, please consider how long you need the backup to operate the system,and what peripherals you want the backup to also operate, if any, such as horns or lights. ContactRKI with this information for assistance selecting an appropriate backup.

11.8.3 Remote horns or lights:

Most RKI Controllers have an audible alarm and alarm LED’s as part of the controller. In manycases it is desired to also have a remote or louder audible alarm or alarm light. RKI can supply avariety of remote horns or lights for warning of personnel to a gas alarm situation. The most com-mon of these are as follows:

11.8.3.1 Red Rotating Beacon:This beacon is powered by 115 VAC, and is effective at attracting attention even in noisyor outdoor areas. This Beacon is RKI Part number 51-0055RK.

11.8.3.2 AC Vibratory Horn: This is a very loud and obnoxious vibratory horn (100db at 10 feet) for use in outdoorareas, high noise areas, or other areas where an unmistakable noisemaker is desired.This horn is RKI Part number 52-0002RK.

11.9 Custom Systems:

RKI has many other systems, sensors, and solutions to gas monitoring applications. We also can designcustom systems if one of our standard ones will not do the job. Please feel free to contact RKI SystemsApplications Engineering at (800) 754-5165 to discuss your application.

11.10 Ordering the system:

Now that the system selection has been made, you may order the system in one of several ways. Ballparkpricing is provided in the pricing section of this manual, but please note that prices are subject to changewithout notice so may have changed since the printing of this manual. For current pricing, please contactRKI, the RKI distributor in your area, or the RKI Rep for your area. If you have any question who to con-tact, please contact RKI.

11.10.1 Distribution: RKI has a distribution network for our products in most areas. If there is an active RKI FixedSystem Distributor in your area, and you have received this manual from one of them, then yourorder should also be placed with them.

11.10.2 RKI direct: If there is no active RKI Fixed Systems Distributor or Rep in your area, then you should contactRKI at (800) 754-5165 (or Fax RKI at (510) 441-5650) to place your order.

11.10.3 RKI also has regional factory representatives that provide technical assistance to our distributorsand customers to help with the selection of the proper equipment. Orders may be placed with thefactory representatives for forwarding to RKI or may be sent directly to RKI instead.

11.11 Taking delivery of the system:

11.11.1 Installation of the system:

System should be installed by a qualified electrician technician, and in conformance with all localbuilding codes, electrical codes, and fire codes. Follow the installation instructions provided in theinstruction manual for wiring information, and system operation. Take care to make connections tothe proper terminals, and do not apply power to the system until all wiring is completed.

11.11.2 Startup of the system:

Once power is applied, allow the system to warm up, and then check the system for proper oper-ation of gas sensors and alarms. Confirm operation of all peripheral devices such as fans or horns.Confirm calibration of the system with use of a calibration gas source. Calibration gases are avail-able from RKI. If you require assistance with startup of the system, RKI can provide field servicefor startup and training at reasonable prices, from either the factory direct, or from one of our ser-vice centers or distributors. Please contact RKI Instruments Field Service at (800) 754-5165.

11.11.3 Maintaining the system:

Once the system is installed and operating, it is very important to service and maintain the sys-tem. The system must be calibrated periodically. The necessary frequency of calibration variesfrom application to application, and needs to be determined from actual use. In benign applica-tions where the sensor will encounter gas very infrequently, the sensors will likely hold up betterthan in corrosive or wet environments or areas where frequent or high exposures are common.Typically, calibrations can be done on 3 to 6 month intervals, but some applications may require itmore frequently. Calibration can be performed either by your own trained personnel, or RKI canprovide routine calibration and maintenance service at reasonable cost.

Other than routine calibration, some systems may also require periodic filter replacement, pumpreplacement, or replacement of other expendable parts such as batteries or absorbent cartridges.Please follow the recommendations in the instruction manual.

F i e l d S e r v i c e R a t e sRKI Instruments offers the following field service rates for servicing our equip-ment at the customers site. Field service rates can be applied to start-up, calibra-tion, troubleshooting, or training. Please note that these rates are broken intoseveral different categories as follows:

Hourly Rate:

$65 per person per hour. This rate is intended for regularly scheduledwork, or short term scheduled work. These rates apply during normalworking hours only, Monday through Friday. In order for these rates toapply, at least one day’s prior notice for the service must be given. A 4hour minimum generally applies, plus travel time and expenses, if any,will be added to the bill. (Hourly rates only apply to customers withinreasonable driving distance from RKI or one of our service centers).Overtime (hours outside of normal working hours, 8-5pm) are billed at $95 per hour.

Daily Rate:

$500 per person per day for 8 hours. Additional hours at $95 per hour. These rates apply to normal workingdays (Monday through Friday, except holidays), and at least one days prior notice must be given.

Weekend and Evening Rates:

$750 per person per day for 8 hours (or $95 per hour; 4 hour minimum billing). Additional overtime hours(over 8) at $120 per hour. At least one days prior notice must be given.

Emergencies:

Emergency service is any service call that does not fall under one of the categories above; any service that can-not be scheduled with at least one day prior notice, or that is needed on a normal holiday. Rates for emergencyservice are $1000 per person per day, (or $130 per hour; 4 hour minimum billing). Additional overtime hours(over 8) are $150 per hour.

In addition to the above rates, travel time, if applicable, will be billed at 1/2 the applicable hourly rate. Travel expenses, includingairfare and hotel, if any, will also be added to the invoice. Also, any parts used such as replacement sensors, calibration gas, etc,will be added to the invoice. Pleasecontact RKI Instruments, Inc. at(800)754-5165 to arrange field ser-vice or training.



Most sensors will respond to families of gases, such as flammables, or acid gases, or hydrides, that have a chem-istry that behaves similarly on the sensor. In addition, they may respond to other gases that are outside the intend-ed family of gases, and may be considered as an "Interfering Gas". Careful evaluation of a detection area or sam-ple stream must be done to determine if there will be any other gases present besides the one(s) that you wishto detect, and if these other gases may cause an unwanted signal on the sensor.

Interference charts for several of RKI's most common sensor types appear on the following pages. These chartsshow the sensor type, the gas the sensor was calibrated to, the "interference" gas and concentration applied, andthe response obtained, if any. Examination of these charts can be very useful in determining if a particular sensortype will perform adequately in a given application.
