ABSTRACT:
A probe for sensing the position of an object relative to a reference point includes a contact tip extensibly mounted on a probe body by means of a piston assembly which transmits minimal force to the object through the tip after the tip contacts the object. The piston assembly includes a fluid driven piston which is normally spring biased to a retracted position. The tip is mounted on one end of a shaft which is slidably mounted on the piston so as to be displaced relative to the piston only after the tip contacts the object. The other end of the shaft forms the core of an LVDT which transforms linear displacement of the shaft into electrical signals indicative of the position of the object relative to the reference point.
