A gauge for measuring the sizes of mechanical workpieces including a support frame, movable feelers adapted to touch the work to be measured, a flexible lamina associated with the feelers, electrical position transducers having displaceable movable elements, at least one inextensible axially movable wire connecting the lamina to the movable elements of the transducer. The movement of the feelers in turn move the lamina, wire and movable transducer element whereby an output signal is generated responsive to the axial position of the wire.

Gauge with electric position transducers to measure the sizes of

A movable measuring system for a gauge of the direct feeling type including first and second movable elements supported by a frame and supporting in turn respective feelers adapted to contact the workpieces to be measured, substantially rigid members associated with the movable elements and joined together through a link adapted to allow displacements of the feelers and of the movable elements and to transform them into displacements comprising rotations of the rigid members around an axis defined by the link and a transducer to detect the displacements of the axis. The movable elements are displaceable to allow the feelers to approach and to move away from each other. The axis is on its turn movable with respect to the frame. The transducer has a movable element suspended to an inextensible wire stretched by a spring connected between the movable element of the transducer and the frame of the gauge. The wire is adapted to move longitudinally according to the displacements of the axis defined by the link. The link is constituted by a thin elastic lamina substantially bent with a U-shape or a V-shape, the external faces of the U or V being welded to relevant faces of the rigid members. The axis of rotation relative to the rigid members is defined by the longitudinal axis of the central section of the lamina.
