MAGNETIC ABSOLUTE POSITION SENSOR FEATURING A VARIABLE LENGTH OF THE INDIVIDUAL ENCODING SEGMENTS

摘要

The objective is to provide a measuring device, which makes it possible to determine the absolute position (s) of a movable member comprising a permanent magnetic encoder (2) with a number of magnetic segments (4), the polarity of which alternates in the direction of measurement (r). To this end, a measuring device (1) includes two magnetic-field sensitive sensor elements (6) being spaced apart from each other, the length of the segments (4) of the encoder (2) being selected differently in the direction of measurement (r).
