WIKA Model TRW 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. In addition, the sensor can measure continuously without transmitting every measured value. This means: high security with low data and energy consumption. All data is available digitally in a cost-efficient way and allows automated analyses.

Easy integration thanks to several radio-standard options
Thanks to numerous process connections and the two available standards − LoRaWAN^® for the kilometre range and Bluetooth^® for the metre range − the instrument can be flexibly configured.

Numerous application possibilities – also as retrofit
Via retrofit, machinery or moving parts can be configured smartly − without having to plan and document cable routing. Particularly when no continuous measurement is needed, cost advantages can be realised.

Robustly built, permanently reliable temperature measurement
The instrument is built to be robust and vibration-resistant. The battery is preassembled and can be replaced easily. It is not necessary to replace the entire resistance thermometer.
