Slot resistance thermometer with coiled measuring wire
Application
To measure and monitor the winding temperature of electric motors or generators, the sensors are attached directly to the copper winding in the stator. Due to the Pt100 measuring winding, the NWT are active over the entire length and can be adapted to different motor sizes. No induction voltages occur in the resistance winding, which avoids measurement errors.
