Abstract
Apparatus for checking diameters of workpieces in a broad range of operation, including two arms moving with a scissorwise movement. The two arms carry relevant measuring heads and are coupled to coaxial shafts. A rotary transducer has two moving elements coupled to the coaxial shafts. A processing and control circuit includes pre-selectors for zero-setting the apparatus with reference to different diameters to be checked. The processing and control circuit provides a measurement signal depending on the output signals of the measuring heads and of the rotary transducer.

An electronic apparatus for checking the linear dimensions of mechanical workpieces in a wide range of operation including:
- a frame;
- two parallel shafts supported by the frame;
- two arms fixed to the shafts and rotating with them;
- transducer means to supply a signal responsive to the reciprocal movements of the two arms;
- a processing, indication and control unit;
- and control means to command the movements of the two arms comprising two measuring heads adapted to co-operate with the workpiece, arranged at the ends of said arms, said transducer means including a rotary transducer with two elements fixed to said shafts, said processing, indication and control unit being connected to the measuring heads and to the rotary transducer in order to provide signals responsive to the dimensions to be checked and to said control means, in order to activate the same control means.
