Abstract
A measurement sensing device has a probe element that is displaced by an object to be measured and is acted on by an electric motor when in its displaced position to control the pressure with which it bears on the object. A control circuit for varying the standstill torque of the motor comprises means for compensating for variations in any biasing force applied to the probe element by its mounting, means for compensating for weight effects acting in the direction of measurement, and means for adjusting the predetermined value of the bearing pressure.
