Position measuring device has material measure and sensing head moving against material measure, where material measure has multiple pseudorandom divalent markings with constant measuring partition

摘要

The position measuring device (10) has a material measure (11) and a sensing head (13) moving against the material measure. The material measure has multiple pseudorandom divalent markings (12) with a constant measuring partition (t). Multiple sensors are provided in the sensing head, which are arranged so that they sense multiple divalent markings in a position of the position measuring device. A sensing signal is guided indirectly to both the absolute detector and the interpolator.
