The Tip Sensitive Bearing Thermocouple Probe is a tubular sensor in which the sensing junction is encased in a copper alloy tip. 

This allows for increased accuracy and sensitivity to temperature changes at the point of contact in bearings. Inserted at an opening on the bearing housing, they are used in electric motors and generators for continuous sensing of the bearing temperature. 

Bearing sensors can be used with a fluid sealed adjustable spring loaded holder for proper loading in any depth hole to maintain contact with the bearing surface.
