Motor Winding RTD Temperature Sensor

Motor Winding RTD Temperature Sensor

Motor Winding RTD Temperature Sensors are used to measure winding temperature of large Motors, Generators etc. These sensor are sandwiched between the windings of Motors/Generators. Unlike on/off devices, It allows continuous measurement of winding temperature. Normally six sensors are recommended for each motor, Two per Phase. This RTD are generally flat type in construction and are available in various sizes.
