WIKA | Miniature Resistance Thermometer With Wireless Transmission

The model TRW is a radio-based resistance thermometer for monitoring medium temperatures of all types. Resistance thermometers in this series can be installed directly into the process or combined with a large number of thermowell designs. It uses the licence-free LoRaWAN^® and Bluetooth^® radio standards and is used, for example, on mobile equipment and remote measuring points. Thanks to intelligent measurement and transmission control and a replaceable battery, the sensor can be operated for years without maintenance.

Long battery life through intelligent measurement control
The intelligent configuration allows measurement and transmission intervals that are dependent on the measured value.
