ABSTRACT:
A measuring head comprises an integral member defining a support portion, a plurality of fulcrums and a corresponding plurality of movable arms carrying feelers. The fulcrums are aligned for defining a single axis of rotation for the movable arms. Position transducers electrically detect the positions of the movable arms. Two measuring heads are employed for realizing a snap gauge for simultaneously checking a plurality of diameters.
