ABSTRACT:
A position sensing device for indicating the relative position of the device with respect to an external surface. A main support member houses a plurality of angular position sensing probes which are each associated with transducers that provide an indication of the relative position of each probe to the support member so that when the probes engage an external surface, information is provided which can be used to indicate the relative position of the device with respect to the external surface. An additional lateral position sensing probe can also be mounted in the support member to indicate exact axial alignment with a hole or other discontinuity in the external surface.
