Function and system design

Measuring principle Electronic monitoring and conversion of input signals in industrial temperature measurement.

®

Measuring system The iTEMP HART

TMT182 temperature head transmitter is a 2-wire transmitter with analog output.
It has measurement input for resistance thermometers (RTD) in 2-, 3- or 4-wire connection,
thermocouples and voltage transmitters. Setting up of the TMT182 is done using the HART® -Protocol
with hand operating module (DXR275, DXR375) or PC (e.g. configuration software ReadWin

®

2000 or

FieldCare).

Input
