Meas tip sensitive bearing RTD probe- spring loaded fitting

The Tip Sensitive Bearing RTD Probe–Spring Loaded Fitting consists of
a bearing probe, holder and optional connection head. The quick release
spring loaded holder allows for adjustability to ensure the Copper tip
remains in contact with the bearing surface for reliable readings and
faster time response. Inserted at the opening on the bearing housing,
they are used in electric motors and generators for continuous sensing of
the bearing temperature.
The T Quick fitting has a shorter quick release knob for use with a
transmitter in a connection head.
