Abstract
A method and apparatus for sensing both axial and angular displacements of a collar relative to a shaft. The invention provides transmitting and receiving electrodes on the shaft and coupling electrodes on the collar. Displacements in the axial or angular directions vary the amount of signal conveyed between the electrodes relative to the quantities sought to be measured. An electronic package provides the appropriate signals and allows multiplexing of the data.
