Endress+Hauser TMR31 Compact Thermometers

Endress+Hauser TMR31 Compact Thermometers feature an integrated sensor and transmitter for fast and accurate temperature measurement. These thermometers offer a compact, stainless-steel design for space-saving installation. The TMR31 compact thermometers deliver extremely fast response times for real-time monitoring and high measurement accuracy with a Pt100 Class A sensor. These thermometers measure temperatures ranging from -50°C to 150°C (-58°F to 302°F), or up to 200°C (392°F) with an extension neck. The TMR31 compact thermometers feature a 4-wire RTD or PC-programmable transmitter with a 4mA to 20mA output range. Typical applications include temperature measurement in tanks and pipelines, general industrial process monitoring, food and beverage, life science (general use), and packaged equipment requiring compact sensors.
