A protective device includes at least one pair of conducting wires stretched tightly along a machine component. The wires are guided in cutouts in the partitioning legs of a bellows which at least partially covers the machine component. The shape or a metallization of the legs causes an electric contact to be made between the wires of the pair when the bellows and partitioning legs are displaced by transverse forces acting thereupon. In this way, the emergency circuit of the measuring apparatus can be actuated.
