Abstract
A probe is used to detect axial movement of a rotating part such as a shaft. The probe includes a probe tube portion that protrudes into an annular groove on the rotating part. When the rotating part moves axially, one or the other side surfaces of the groove contacts the probe tube. This contact leads to a changed state of the probe, that is sensed by a sensor.
