Temperature difference

-60 .. + 180 ° C (temperature class H)


Temperature sensors are installed in the winding slots for temperature measurement and for protection against insulation damage in the event of overheating. Temperature sensors should be installed in the hottest part of the winding for best efficiency results.

The sensor consists of a resistance thermometer, a shrink tube made of PTFE and a connection cable.

Sensor type, length, accuracy, cable insulation and connection method can be individually selected for the respective application.
