Application
This range of temperature transmitters are available as either head transmitters (TMT187/188) or as rail mounted devices (TMT127/128). The TMT187/188 head transmitters can be installed in the form B sensor head and have a fixed measurement range as well as a 4 to 20 mA analog output.
Input:
TMT127/187 resistance thermometer (RTD) or
TMT128/188 thermoelements (TC)Function
The TMT127/187 RTD temperature transmitter is a two-wire transmitter with an analog output and a three- or four-wire resistance thermometer input.
The TMT128/188 TC temperature transmitter is a two-wire transmitter with an analog output and thermocouple input.
