Abstract

There is described an arrangement for detecting a change in a position between two parts which can be displaced in relation to one another. The arrangement has at least one electromechanical registering device having a monitoring chamber, which is shielded from manipulations taking effect from the outside, a number of monitoring bodies in the monitoring chamber, the number comprising at least two components and these components differing from one another in terms of a physical parameter, motion transfer means, which, in the event of the change in the positioning being returned to an initial state, cause the monitoring bodies to be moved from a first monitoring arrangement into a second monitoring arrangement. A sensor device has sensors which generate a sensor signal corresponding to the physical parameter of a monitoring body associated with each sensor in the first and second monitoring arrangement, and each sensor signal is fed to an evaluation unit.
