Abstract
A plug comparator for checking the diameter of holes of mechanical parts comprising a support, a movable measurement unit and a protection casing. The movable measurement unit comprises 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 electric cord to an electric supply and indication group. The casing has a lower base with a frustoconical seat for the fitted housing of a closure plate. The closure plate has a cut in diametral direction which subdivides it into two adjacent portions connected by a third portion which is elastically yieldable so as to permit fitting the closure plate in the frustoconical seat.
