Absolute precision transducer for linear or angular position measurements

摘要

A precision cyclic position measurement transducer capable of giving an indication of the relative position of two movable transducer elements within one of a plurality of measurement cycles is combined with binary- coded and electrically coupled conductor patterns on those transducer elements so that unambiguous indication is given of one of the measurement cycles, the indication changing as the transducer position is changed from one measurement cycle to the next. The improved transducer gives an absolute indication of the relative position of the transducer elements measured in measurement cycles and the position within a measurement cycle regardless of changes in transducer position.
