ABSTRACT:
A device is provided for measuring bearing or shaft wear in an apparatus utilizing a rotating shaft positioned in a bearing. A plurality of magnets are mounted on the rotating shaft and at least three coils forming at least two pairs of coils are mounted on a stationary housing surrounding the shaft. Means are provided for measuring the change in induced voltage for each pair of coils independent of shaft rotation speed, ambient temperature, the flux density of the magnets and the concentricity of the bearing and shaft diameters.
