Signal transmitter with two-wire measurement systems for converting the measured temperature to a 4-20 mA signal. Suitable for mounting on standard DIN-RAIL profile, and available for PT100 or Thermocouple.


Using a TRM-20 transmitter it is possible to convert a temperature measurement value to a standard 4-20 mA measurement signal. This makes it possible to convert a large number of diverse temperature signals to, for example, a standard PLC input which allows larger distances to also be bridged. The TRM-33 series of transmitter heads can be directly built into the connection head of the temperature sensor, whilst the TRM-20/30 series of transmitters is intended for mounting on DIN rails in for example switch boxes. We adjust the TRM20 transmitters according to the desired measurement system and measurement range.

  • TRM20W: DIN-rail transmitter for PT100–IEC60751–3 lead.
  • TRM20T: DIN-rail transmitter for Thermocouple J or K.
Description Signal transmitter intended for mounting on a standard DIN-RAIL profile.
