METHOD AND ARRANGEMENT FOR CORRECTION OF EVALUATION OF A SWITCHING THRESHOLD OF A MAGNETIC SENSOR

摘要

The method for correction of evaluation of a switching threshold of a magnetic sensor arrangement includes evaluating switching edges of a transmitter signal produced by a moving transmitter element and generating a signal output when the switching edges exceed or fall below a default threshold value. Individual threshold values are determined for each switching edge during the course of a measurement cycle to correct the default threshold value. This occurs by determining respective maximum and minimum values for each switching edge and then averaging them to obtain an average value for each switching edge. Then the average values are stored in a non-volatile memory as individual threshold values for subsequent correction.
