3.1 Application range
The SITRANS TR200 and SITRANS TR300 temperature transmitters are 2-wire devices for
DIN rail installation. They are suitable for use in all sectors, thanks to their universal sensor
input and type of installation. The following sensor and signal sources can be connected to
their input stage:
● Resistance thermometer
● Thermocouples
● Resistance-type transmitter/potentiometer
● DC voltage sources
The output signal is an output current of 4 to 20mA that corresponds to the sensor
characteristic curve.
Explosion-proof transmitters can be installed and operated within hazardous area in
accordance with the information on the EC type examination certificate to ATEX and these
operating instructions.
