PCT No. PCT/DE97/00746 Sec. 371 Date Feb. 8, 1998 Sec. 102(e) Date Feb. 8, 1998 PCT Filed Apr. 12, 1997 PCT Pub. No. WO97/39929 PCT Pub. Date Oct. 30, 1997A device for detecting electromagnetic stray effects in systems with at least two inductive sensors which provide an essentially periodic output signal, performs a signal evaluation for evaluating signals of the sensors, a test for detecting an electromagnetic stray effect, whether periods of the signals to be evaluated lie within a period length of expected stray effects, a test, if applicable, whether detected signal progressions have at least a progression typical for stray pick-up, plausibility tests by means of at least one further detected signal in which a signal to be checked is compared with parallel measured other signals, and detecting a stray effect only if all tested conditions provide a result which is typical for stray effects.
