Hauser+EndressThe Power of Know How

This datasheet has been downloaded from http://www.digchip.com at this page

Measuring System The Prosonic T compact ultrasonictransmitter is a complete measuringpoint within itself. The simplest versionallows access to all functions requiredfor basic operation. Calibration can becarried out using the four pushbuttons, +, V, H on the instrument without theneed for other equipment. With a plug-in display, the completeEndress+Hauser user matrix can beaccessed.

The basic functionality may beenhanced by other optional operatingpossibilities or integration into a processcontrol system, e.g. via: 2-wire loop-powered 420 mA

Operation Prosonic T compact transmitters offeroperation tailored to all level applications: Local calibration or matrix operation

by simply pressing buttons Smart remote operation and display

via the handheld terminal Comprehensive operating and display

software for personal computer Calibration in the control room via a

Silometer FMX 770 or FXN 671.

Matrix OperationProsonic T can be operated by usingthe keyboard and display, a handheldterminal, a Silometer transmitter(FMX 770, FXN 671) or via a processbus. The identical operating matriceensure that procedures are uniform andclear.

Operation via DisplayParameters are entered and valuesdisplayed by using the four pushbuttons, +, V, H on the front panel of the device.The optional display provides access tothe Endress+Hauser operating matrix andto a wide selection of additional functions. The following application parameters

are available:- Liquid- Rapid changes in levels of liquids- Measurement when mounted in the

dome cover- Coarse-grained solids- Conveyor belt

Automatic suppression of three fixedtarget echoes

Linearisation (11 points) First echo detection (double echo) Automatic suppression of stirrer

echoes

Operation Without a DisplayThe basic functions of the Prosonic Tcan be set by using just the fourpushbuttons , +, V, H on the front panelof the instrument. Empty and full calibration Parameter protection by entry locking

PROFIBUS-PAThe PROFIBUS-PA is an open fieldbusstandard for connecting sensors andactuators, which may also be inexplosion hazardous areas, to one buscable. The two-wire sensors aresupplied with power over thePROFIBUS-PA and the processinformation of the sensor is digitallytransmitted.

The number of instruments operated atone bus segment: up to 10 for EEx ia applications up to 32 for non-Ex applications

Operation via Handheld TerminalWith a handheld terminal, the Prosonic Tcan be configured, values displayed andadditional functions activated fromanywhere on the 420 mA signal line.There are two versions: Commulog VU 260 Z (INTENSOR) Universel HART Communicator DXR 275

Operation with Commubox Commubox FXA 191 connectsintrinsically safe Smart transmitters withINTENSOR or HART protocols to theRS 232 C serial interface of a personalcomputer, allowing remote operation bythe Endress+Hauser Commuwin IIoperating program.

Installation Mounting Always mount the sensor such that the

distance between it and the maximumproduct level exceeds the blockingdistance. The lower edge of thetransmitter should, however, projectbelow the roof of the tank or silo.Exception: mounting in a nozzle.

Never mount two Prosonic T in avessel because the instruments maynot function correctly.

Do not mount the sensor in the centre ofthe vessel roof.

Position the sensor at right angles tothe surface of the material.

Do not measure through the fillingcurtain.

Blocking DistanceDue to the ringing time of the sensor,there is a zone immediately below it inwhich returning echoes cannot bedetected. This so-called blockingdistance determines the minimumdistance between the sensor and themaximum level in the tank or silo (seeTechnical Data for values).

Interference SuppressionInterference echoes coming frominternal fittings can be suppressed byusing the fixed target suppressionfunction. The signals are then no longerrecorded or used for further processing.The ultrasonic pulse leaves the sensoras a narrow beam which widens withincreasing distance from the device.Every object within this beam producesan interference echo which is receivedby the sensor.

Mounting on a NozzleIf the maximum level to be measuredfalls within the blocking distance, thetransmitter must be mounted on anozzle. No build-up should form in the nozzle. The recommend nozzle dimensions

are limits, within which the nozzle canvary. Check that the nozzle diameter islarge enough, but keep the nozzlelength to a minimum (see figure).

The inner surface of the nozzle shouldbe as smooth as possible no edgesor welding seams.

Measuring Range The maximum measuring range of theProsonic T is limited by the conditions atthe measuring point and the reflectioncharacteristics of the product surface. Optimum conditions are achieved if:

the surface of the liquid is calm andwithout foam,

no large concentrations of vapour arepresent in the tank,

the solid material is hard andcoarse-grained,

no dust is present in the silo, temperature layering in the tank or silo

is low.

Example for Calculating RangeCheck the factors affecting yourmeasurement in the table to the right.Add up their attenuation values (dB).

Temperature difference in silo max. 40C (104F) 10 dB

Low amount of filling curtain in detection area 5 dB

Surface of liquid with strong turbulence 20 dB

Sum of attenuation values 35 dBRange below these factors thus approx. 5.8 m (19 in) with 2" sensor.
