Abstract

In the device disclosed, four coils (11 to 14) are mounted on the inner wall of a support (10) made from an electrically non-conductive material and co-operate with a conducting part (20) provided with regions (21, 22) made from an electrically conductive material. The conducting part (20) is symmetrical in shape and has two regions (21, 22) which are larger than one of the coils (11 to 14). When the region of overlap between the region (21, 22) and one of the coil (11 to 14) is reduced, it is increased by the same amount in the next coil. The coils can be interconnected and mutually arranged so as to eliminate errors by compensating the radial play.
