The Tip Sensitive Bearing RTD Probe is a tubular sensor in which the
sensing element 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.
