ABSTRACT:
A device for determining the position of a workpiece face comprising: a body having a longitudinal axis and a longitudinal bore concentric with the longitudinal axis; an extendable member having a first end movable within the bore along the axis, an arrangement on the member for moving the first end of the extendible member, a coupling member fastened to the first end of the extendable member for movement therewith, an arrangement for relesably securing a second end of the extendable member within the bore, a sensor head, a resilient member for attaching the sensor head to the coupling member, an essentially spherical contact tip attached to the sensor head and aligned with the axis for travel along an axial path in conjunction with the movement of the first end of the extendable member, and a deflecting arrangement for deflecting the tip out of alignment with the axis, the deflecting arrangement being attached to the body at a known angle with respect to the longitudinal axis and positioned in the path of the tip, whereby deflection of the tip causes at least one point on the surface of the tip to advance toward the workpiece surface along a path radial to the axis.
