PCT No. PCT/DE89/00458 Sec. 371 Date Dec. 3, 1990 Sec. 102(e) Date Dec. 3, 1990 PCT Filed Jul. 11, 1989 PCT Pub. No. WO90/01140 PCT Pub. Date Feb. 8, 1990.A measuring device for contactless determination of a change in a linear travel or angle of rotation includes two bodies movable relative to one another, and at least two electrical elements arranged on one of the two bodies and connected in at least one electrical bridge circuit. Electrical characteristic values of the two electrical elements vary in accordance with relative change assigned areas of the other of the two bodies. The two electrical elements have different electrical measurement sensitivities for fixing a place with a highest measurement accuracy and smallest drift errors within a measurement area of the measuring device.
