  Description
   Resistance thermometers of this series are used as universal thermometers for the measurement of liquid and gaseous media.

   They can be used for pressures up to 40 bar (special designs to 400 bar dependent on insertion length and diameter). All electrical components are protected against splashed water and are designed to withstand vibration.

   Insertion length, process connection, measuring elements,etc., can be selected for each application.

   The TR31 resistance thermometer consists of a protection tube, which can be fixed into the process using a permanently-welded threaded connection or a compression
fitting. A version with no process connection is also available.The electrical connection is made via an M12 x 1 circular connector.

  Output signal Pt100
   The model TR31-P resistance thermometer is available with a direct Pt100 signal.

   Output signal 4 ... 20 mA
   In the model TR31-W resistance thermometer, a softwareprogrammable 4 ... 20 mA output signal is built in. Thus the measured temperature values can be transmitted safely and simply.
