Abstract
The sensor comprises a reference body (1) in which there is displaceably mounted a movable body (3) bearing a measurement finger (6) and a pick-up (9) which translates the displacements of the movable body into electrical signals. The movable body (3) has a stop (18) subjected to the opposing pressures of two springs (19, 26), one of which (26) lies in the extension of the rod of the piston (24) of a single-acting pneumatic cylinder-piston unit (23). When the cylinder-piston unit is at rest, the measurement finger is disengaged by pressure of the spring (19) opposite said cylinder-piston unit. When the cylinder-piston unit is extended, the measurement finger is pressed against the part to be measured by the action of the spring (26) borne by the rod of the piston. The finger of this sensor is thus disengaged in the position of rest of the cylinder-piston unit and can easily be brought towards the finger of another sensor of the same type in the direction of the taking of the measurement.
