Description

Wherever the process temperature has to be indicated on-site and, at the same time, a signal transmission to the central control or remote centre is desired, the model TGT73 intelliTHERM ® can be used.

Through the combination of a mechanical measuring system and electronic signal processing, the process temperature can be read reliably, even if the voltage supply is lost.

Due to the wide variety of possible designs, the model TGT73 gas-actuated thermometers can be perfectly adapted to any process connection or location. With the adjustable stem and dial version, the case can be adjusted precisely to the desired viewing angle.

Special features

Cost-effective “2 in 1” temperature measurement
Compact design
Scale ranges from -200 ... +700 °C [-328 ... +1,292 °F]
Plug-and-play, thus no transmitter configuration necessary
