Operation and system construction
Measurement principle Electronic measurement and conversion of input signals in industrial
temperature measurement.
Measurement system The iTEMP

TMT 182 temperature head transmitter is a 2 wire
transmitter with an analogue output. It has a measurement input for resist-
ance thermometers (RTD) in 2-, 3- or 4-wire connection, thermocouples and
voltage transmitters. Setting up of the TMT 182 is done using the HART
®
-
Protocol with hand operating module (DXR 275) or PC (COMMUWIN II).
Input values
Measurement value Temperature (temperature linear), resistance and voltage.
Measurement range Dependent on the sensor connection and input signal, the transmitter
evaluates a number of different measurement ranges.
