Abstract
An apparatus for checking the dimensions of mechanical workpieces in movement with respect to the apparatus, including at least one feeler adapted to cooperate with the surface of the workpiece, or workpieces, at least one transducer connected to the feeler for providing a signal responsive to the dimensions, processing apparatus connected to the transducer for processing the signal and providing a measurement signal, the processing apparatus including a limiter circuit adapted to receive the signal responsive to the dimensions and limit it as to variations in a pre-established direction, providing a relative output signal, output apparatus connected to the processing means to receive and utilize the measurement signal and control apparatus. The processing apparatus include a further limiter circuit, adapted to receive the output signal of the first limiter circuit and carry out limitations regarding even variations in the opposite direction to the pre-established one, the resultant signal being utilized to obtain the measurement signal. The control apparatus enables and inhibits the further limiter circuit.
