Operation and system construction

Electronic measurement and conversion of input signals in industrial temperature measurement.
®
The iTEMP PA TMT184 temperature head transmitter is a 2-wire transmitter with measurement
inputs for resistance thermometers and resistance transmitters in 2-, 3- or 4-wire connection, ther-
mocouples and voltage transmitters. Applications are in the measurement and control areas for pro-
cess monitoring. The TMT184 Setup is done using the PROFIBUS-PA
PC software (e.g. Commuwin II).
More detailed information for project planning can be found in the operating manual
See »Further documentation« on page 81.
