Abstract

A plug comparator for checking the diameter of holes in mechanical parts, having a movable measurement unit comprising two movable arms bearing respective feeler elements which come into contact with the part to be checked. A position transducer detects the position of the movable arms and is connected by an electrical cord to an electrical supply and indication group. The movable unit comprises a single member of stamped plate having two portions which constitute the arms. The two portions have two sets for the ends of a spring which act on the arms, two seats for two mutually movable elements of the transducer, seats for the feeler elements and for devices for locking the feeler elements, and stop elements which limit the movements of the arms towards each other.
