The TX206TH is a cost effective“smart” in head transmitter thataccepts thermistor temperaturesensors and converts sensoroutput over a configured range toa standard industrial (4 to 20) mAtransmission signal.

A variety of thermistor typesare available when using theconfiguration software: selectthermistor type, temperaturerange, units and burnout direction,without requiring calibrationequipment.

PC configuration is performedquickly using our new USB portdriven configurator by simplyconnecting two clips to theTX206TH loop terminals andfollowing the software instructions.Calibration set-up may be savedas a file on the PC for later use.

Alternatively, a single pushbuttonand LED indicator allows the userto configure transmitter rangeagainst a manually set inputcondition. A red LED is includedto help guide the user. The LEDalso operates as a sensor errorindicator.

Transmitters can be factoryconfigured for any range specifiedat the time of order, removing theneed for user configuration. Extralead time is required.
