Slot resistance thermometer

Bifilar NWTs

NWTs with a bifilar Pt100 measuring winding allow the temperature to be determined across the entire active length of the measuring winding. Adapting them to the respective design of the winding slot of electrical motors or generators guarantees an optimum measuring result.
