ROTARY SHAFT POSITION TRANSDUCER

摘要

HIGH RESOLUTION AND WIDE RANGE SHAFT POSITION TRANSDUCER SYSTEMS. Apparatus for producing digital signals signifying the angular position in each revolution and the number of revolutions of a shaft which rotates a plurality of times. The apparatus includes two rotary position transducers which are coupled to each other and to the shaft. Both of these transducers rotate a plurality of times in response to the rotations of the shaft, one of the transducers rotating at a different speed than the other. Each transducer produces signals which are individual to the respective transducer and are the same for each rotation of the respective transducer.
