Abstract

The sensor position is indicated with respect to a reference position and a locking device holds the sensor in its rest position. The locking device has two arms hinged on each other; the first arm end interacts with a collar on the movable sensor, and the other arm rests on a relatively fixed point of the system, so that a movement of the arms in one direction moves the sensor to its rest position. The arms can be locked in this position, one of the above arms has a latch which engages a notch in the other and the latch is pressed by a spring to guiding surface on the other arm leading to the notch, so that in a position when the sensor is at rest, the latch automatically falls into the notch.
