Endress Hauser  TMR31-A1BABBAX1AAA Compact thermometer

Field of application

With cost efficiency, optimal use of space, reliable operation, easy installation and commissioning the TMR31 fulfills the requirements of modern process measurement technology. Vibration-proof integrated thin-film sensors guarantee highest operational safety at the fastest response times.

The TMR31 compact thermometers are used to measure temperatures from -50 °C to +150 °C (-58 °F to +302 °F), or up to +200 °C (+392 °F) with neck. The most common installation locations are tanks and pipes. TMR31 with process connections for general applications.
