ABSTRACT:
Apparatus for measuring the wear of a shaft bearing includes a liquid, a source of fluid, a valve, sight gage and a transducer. The transducer has a probe which may be urged against the shaft by admitting fluid from the source to a chamber in the transducer. The liquid is in enclosed subsystem comprising the sight gage, an expandable chamber in the transducer and a connecting line. As the probe is urged against the shaft, the expandable chamber expands in a relationship to the movement of the probe. More liquid enters the expandable chamber, causing a corresponding decrease of liquid in the sight gage which is measurable. Upon completion, the fluid is vented, which allows the probe to return to a rest position.
