Description
3.1
Application range
SITRANS TH200 and SITRANS TH300 transmitters can be used in all industries. Their
compact size means that they can be installed in connection heads of type B, in accordance
with DIN43729, or larger. Their input stage means that the following sensor and signal
sources can be connected:
● Resistance thermometer
● Thermocouples
● Resistance-type transmitter/potentiometer
● DC voltage sources
The output signal is an output current of 4 to 20 mA that corresponds to the sensor
characteristic curve.
Explosion-proof transmitters can be installed and operated within potentially explosive
atmospheres in compliance with the information given in the relevant certificates and
approvals and in these Operating Instructions.
