Position Transducer.
Abstract
An electrical transducer for indicating the position of an element movable in a predictable path, such as angular rotation, has no electrical parts on the movable element. A magnetic mounted to the movable element traces a fixed path which lies adjacent to a stationary tubular enclosure containing liquid suspending a mass of ferromagnetic, electrically conductive material, the magnet drawing the mass of particles along within the tube on movement in its fixed path. Electrodes spaced on opposite sides of the tube along the length of the tube are electrically coupled by the mass of particles, whereby to indicate the position of the movable element. (Author)
