ABSTRACT:
An angular displacement transducer has a highly magnetically permeable target which preferentially directs the flux of a fluctuating magnetic field through one of two or more cores. The fluctuating magnetic field induces voltages in secondary windings around the cores. Output signals which vary with the angle of the target about an axis are obtained by connecting pairs of secondary windings differentially. By choosing targets of different shapes the output voltage can be made to vary with angle as a sine wave or as a triangular wave. Transducers according to the invention can be rugged and accurate while retaining a simple construction.
