DEVICE FOR MEASURING THE ABSOLUTE POSITION OF AT LEAST TWO MEMBERS THAT ARE MOVABLE OR ROTATABLE RELATIVE TO EACH OTHER

摘要

The aim of the invention is to create 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). Said aim is achieved by a measuring device encompassing two spaced-apart magnetic field-sensitive sensor elements (6), the length of the encoder (2) segments (4) being selected differently in the direction of measurement (r).
