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.
