Pipe surface resistance thermometers of the TR57-M series are used for non-invasive temperature measurement on pipelines.

These resistance thermometers can be retrofitted at any time to an existing pipe, without opening or interrupting the process. The resistance thermometers can be used in a temperature range from -20 … +150 °C.

The fixing of the measuring insert onto the pipeline is achieved using a pipe adapter. The measuring insert is spring-loaded and the sensor tip is isolated against the ambient temperature through the silicon lining of the pipe adapter.

The measuring insert can be removed for calibration.

All electrical components are protected against moisture (IP67).

The resistance thermometer is available with direct sensor output or integrated transmitter.

Through the compact design, this resistance thermometer is designed specifically for operation in applications with limited mounting space.

Process connection, sensor and connection method can each be selected for the respective application from the ordering information. The electrical connection is made via an M12 x 1 circular connector.
