What Are Field-Bus Systems?A field-bus system is a data network with the objective to receive data from a production process, exchange data betweendevices or machines, control steps or processes in production. Data transmission happens serially with digital signals(equivalent to Internet data transmission.)

The most basic design of such a data network is a 2-wire cable with various individual sensors (e.g. Pressure transmitters),actors (e.g. solenoid valves), controllers, periphery units, and control units (e.g. PLC, industrial PCs) connected at any point.BUS participants need a suitable interface, which transfers flow of data. Each individual component gets its own address.

Structure of a Bus System:

Remarks: Communication of process data is performed by means of every individual sensor, component, and so on,being connected via it’s own wiring to high layer control.

Advantages:• Easy wiring with clear reduction of cabling (best case: only two cables)

• Clear structure

• Diagnostic functions, connected units may be checked on functionality

• All system functions are available in high layer control at any time

• High level of transmission safety, information may be checked on validity through multiple transmissions

• Easy to be enlarged, since at any place of network a unit may be added

• Easy implementation into higher leveled systems:- connection to other bus system- distance diagnostic systems- service units

EEx Component identification for use on applications with an explosion hazard,according to safety class definition.i Intrinsic safety: the circuits are designedso that no spark or thermal effect which canoccur under the test conditions stipulated inthe standard, can cause an ignition of a certainenvironment with an explosion hazard.a Error class “a” signifies that up to two independent errorscan occur on the component without this causing any danger. “a” is the highest possibleerror class. ‘b” is the lower level which allowsno more than 1 error on the component (i.e. if two errors occur) the safety is at risk.“a” specified components can be used in applications which only have “b” requirements.IIC “IIC” is the highest possible flash pointrange in the standard. “II” specifies the areaof application for all environments with anexplosion hazard, except for flame-proof protection. (Flame-proof protection is designatedby 1”)“C” designates the actual flash point range(i.e. the ignitability of the environment.) Class C isthe highest requirement, i.e. the environmentaccepted to be the most critical. The subordinateclasses A and B can be equipped with a “C”registered unit. “C” means, for example, thatgas mixtures with up to 23% of hydrogen willnot ignite.T6 Temperature class“T6” is the highest temperature class speci-fied in the standard which ensures that, at amaximum ambient temperature, the surfacetemperature never exceeds 85°C.Components of temperature class T6 can ofcourse also be used for lower classes T1 - T5.

HDA 6000About HDA 6000 Intelligent Display Unit:The HDA 6000 is a microprocessor controlled display and control unit in standardcontrol panel module housing. A single-chip microprocessor controls all functions.A maximum of 3 analog inputs and 1 analog output is possible. The analog inputsignals are converted by a 10 bit A/D converter and displayed according to themeasuring scale selected by the user. Each of the 4 maximum possible relayscan be allocated to each of the 3 analog sensor inputs or the differentialbetween sensor signals 1 and 2. All operating parameters such as switchingpoints and switch-back (i.e. hysteresis) points can be programmed by means ofthe MODE and SET keys. The relays switch as soon as a pre-set switching pointis reached, or after a programmed delay. This function suppresses the reactionof the relays to short-term and irrelevant variations such as pressure spikes.

Technical Details:

Note: During switching of inductive loads, a protection diode (DC voltage) ora varistor (AC voltage) must be connected parallel to the load.

EDS 300 - ShipbuildingAbout EDS 300 Pressure Switches:The EDS 300 is a compact, electronic pressure switch with digital display. The pressuremeasurement is based on a thin film strain gauge sensor cell in stainless steel. All partsin contact with the fluid are in stainless steel, and are welded together. Since no sealsare required in the sensor chamber, leakage is eliminated.Two relay switching outputs with N/O function and an additional analog output signal (4to 20 mA) enable the pressure switch to be incorporated into the most modern controlconcepts. The switching points and the corresponding hysteresis can easily be adjustedvia the keypad.For optimum adaptation to a particular application, the unit has many additionaladjustment parameters, e.g. switching direction of the relays, switching delay times.Areas of application are pressure or maximum value monitoring on marine transmissions,diesel engines, pumps and general hydraulic and pneumatic systems.

ETS 1700About ETS 1700 Temperature Switches:The electronic temperature switch ETS 1700 is used together with the temperature sensorTFP 100, which was specifically developed for tank mounting.

The 4 digit display can indicate either the actual temperature, one of the switching points,or the maximum temperature. The maximum temperature indicates the highest temperaturewhich has occurred since the unit was switched on or last reset.

The 4 switching outputs can be used to control heating and cooling processes inhydraulic systems, as an example. All switching and switch-back points, which are independent of each other, can be adjusted very simply via a membrane keypad. Forincorporation into monitoring systems (e.g. with PLC), an analog output(4 to 20 mA or 0 to 10 V) is also available.

EVS 3100 Flow Rate SensorAbout EVS 3100 Flow Rate Sensors:The EVS 3100 series flow rate sensors are designed to accurately measure theflow-through volume of fluids in hydraulic systems. The unit uses a stainlesssteel turbine wheel internal to the construction, which converts the media flowinto a 4 to 20mA output signal. The in-line mounting design allows for most accurate and up to date flowmeasurements. The EVS 3100 also offers two additional hydraulic ports toaccommodate additional sensors, ex. temperature and pressure transducers.The design of the flow meter incorporates a lightweight aluminum housing withaccurate and stable measuring elements.The unit uses the Woltmann Turbine principle to measure flow. The fluid entersthe housing and passes through straightening blades, which assist in stabilizingthe media into a laminar flow. The stainless steel turbine wheel is rotated by themedia flow, which then influences the magnetic field of the inductive receiverwith the passing of each turbine fin. The inductive receiver is the sensing elementof this flow meter. This influence produces a voltage pulse in the receiver, whichit then converts into a 4 to 20mA output signal.This design provides precise data within the entire measurement range of theunit, and is relatively tolerant against minimal, gritty contamination. The meteralso allows for exceeding flow of up to 50% of the maximum range for shortperiods of time.

HMG 2020

The HMG 2020 generally distinguishesbetween three measurement options:

1. Normal measurementPurely a display function wherethe measured values are displayedimmediately. Ex: When HMG is measuringwith pressure sensors to act as a digital gauge.

2. Curve measurementThe measured values are displayedand simultaneously stored continuously in the internal memory. The courses of thecurves can be printed out on theprinter as soon as measuring hasstopped, or transferred to a PCand viewed with the software.

3. Log measurementThe measured values are dis-played and can be stored as logentries in the internal memory.This method of measurement isused primarily for long-termmeasurements (e.g. one week, onemonth, one year etc.). The log entriescan be printed out on a printeras soon as measuring has stopped,or transferred to a PC.

The internal memory can store upto 50 different curves and logs with250,000 measured values in total.

To optimize your measurements theunit has a wide variety of additionalfunctions:

• Choice of languageThe user may define which lan-guage the unit will display thedata and parameters.

The HMG 2020 is a portable data recorder for recording pressure, temperature, flow rate, rpm etc. in industrial machinery and systems(e.g. hydraulics, pneumatics). The HMG 2020 can record the measured valuesfrom up to five sensors simultaneously.

• 2 inputs for 4 to 20 mA sensors

• 2 inputs for either 4 to 20 mA or 0 to 10 V sensors

• 1 frequency input for digital signals in the range 0.3 to 30,000 Hz

• The measurement range and the unit for each sensor can be set asrequired (e.g. 0 to 250 bar, -25° to 100°C, 0 to 217 KN). Therefore, the majorityof commercially available sensors with standard output signals can beconnected and evaluated.

• As well as the current measured values, the unit also records the mini-mum and maximum values, in addition to the differential between twosensors of the same type.

• Two trigger possibilitiesDefinition of events which start a curve measurementor which, on a log measurement, transfer the currentmeasured values to memory.Ex: A curve is to be recorded when the temperatureexceeds 50°C or the system pressure falls below 25bar. The two triggers can in addition be linked togeth-er logically (and/or following one another chronologically), sothat data is recorded exactly at the required moment.

• Definable displaysDefine which measured variables should appear onthe unit display.Ex: User display 1 of 5: current temperature value,peak value of the flow rate, minimum pressure valueand current rpm value.

• Identification of recorded curves or logsThe user can program in a specific ‘company name’and assign a specific station number to the systembeing presently worked on. This specifies which sys-tem each measurement was recorded from.

• Printer OptionsThese options enable print outs (black & white or color)to be done on commercially available printers.Additional details can be obtained from the technicalinformation in this brochure, or simply by contacting one of our distributors.

Features:

• Transfer and Storage of curves and logsfrom the HMG 2020 to a PC.

• Viewing of up to 4 different recordedcurve or log measurement simultaneouslyon the monitor.

• Superimposition of curves Parts of different curves can be superimposed in a new graph, for example to show the wear and tear of amachine (new condition/current condition).

• Straight edge functionAs with a straight edge, you can measurethe curves using the mouse (exact timeand amplitude value). Absolute measuredvalues and also relative measured values(measurement in relation to a set marker) canbe displayed.

• Zoom function Using the mouse, part of a graph can beframed. The framed area appears as anew graph, enlarged accordingly.

• Online functionThe portable data recorder measuresand transfers the current measured valuesstraight onto the PC. These are thenimmediately displayed as a graph in realtime (comparable with the function of anoscilloscope). The graph displayed canbe stored if there are any interesting results.

• Portable data recorder Settings can be transferred to the PCand may be stored. The reverse is alsopossible, so, for example, settings fortaking measurements on a particularmachine can be fed into the HMG 2020again and again.

• Data conversionHMGDESK can convert the HMG 2020data into some other data formats. Thismeans, for example, that the recordedcurves can be transferred to many otherPC programs (spreadsheets, database,word processing etc.) and further processed.
