Technical Data

10.1 Operation and system construction

Electronic measurement and conversion of input signals in industrial temperature
measurement.
®
The iTEMP FF TMT 165 temperature field transmitter is a 2-wire transmitter with dual
channel measurement input for resistance thermometers, in 2-, 3-, or 4-wire connection,
thermocouples, voltage transmitters and differential measurement. Applications are in
the measurement and control areas for process monitoring. The TMT 165 is set up using
®
the FF protocol combined with a process control software.

10.2 Input values

Temperature, Ohm, mV, differential measurement or two channel measurement.
The transmitter monitors various measurement ranges dependent on the sensor
connection and input signal.
