ABSTRACT:
A shaft angle transducer particularly suited for use as a magnetic compass card for providing an output signal linear with angular movement over a wide range, such as plus and minus 40.degree., with no zero dead band. A member with a plurality of radial segments, each having relatively opaque and transparent portions, with the proportion of the portions changing from segment to segment to provide an output varying as a predetermined function of angular position. A sensor with radiation source and detector, with the segments moving between the source and detector, with the segments in a disc configuration and in a wheel configuration.
