Abstract
Apparatus for measuring the wear of a shaft bearing includes a source of fluid, a valve, and a linear transducer. The transducer has a probe which may be urged aganst the shaft by admitting fluid from the source to a chamber in the transducer. As the probe is urged against the shaft, voltages provided by the transducer change in a relationship to the movement of the probe. The voltage change is monitored to measure the shaft bearing wear. Upon completion, the fluid is vented, which allows the probe to return to a rest position.
