Abstract
A device for measuring the position of a member for example, the height thereof comprises a frame with a slide movable on said frame which carries a rigid measuring member. A motor is connected to drive the slide through a constant slip torque clutch connected between the motor and the slide. The clutch is a magnetic field clutch so that it urges the measuring member when it is in a measuring position against the object being measured so as to exert the measuring force thereon.
