Stator Slot RTDs


RTD Products has a short range of stator slot RTDs.


These slot, or winding, RTDs are installed in stator windings to monitor the operating temperature of electric motors and generators and prevent overheating. They stretch the length of the winding and so provide an average temperature reading, eliminating potential error that could occur from point sensing at a hot spot.
