PT 100 Bearing RTD

Many applications require continuous temperature monitoring of various devices to measure average temperature in the slot / core, Slot RTDs can detect hot-spot in the winding. The Slot Resistance Temperature Detectors (SRTDs), due to their linear Resistance - Temperature characteristics, is used for temperature sensing, measurement & control of winding / machines.

Temperature up to 200ºC can be monitored and controlled with this type of Slot RTDs.

The Slot RTDs are used widely to monitor the winding temperature of Electric Motors (AC & DC) and Alternators. Due to their various sizes the Slot RTDs can be placed directly in the stator slots.
