Temperature by Endress+Hauser
iTEMP® TMT84
Temperature head transmitters with PROFIBUS® PA protocol
 
 

The new iTEMP®  TMT84 from Endress+Hauser with PROFIBUS PA protocol replaces the well known iTEMP® TMT184. To make the change from the previous iTEMP® TMT184 model as smooth and simple as possible, the iTEMP® TMT84 has a compatibility mode. This functionality is particularly helpful when replacing units in the large installed base. The new TMT84 has two sensor inputs for resistance thermometers, thermocouples, voltage or resistance transmitters. Functions that provide the greatest measure in safety, availability and risk minimization in critical applications will be available.
