  • Apparatus for measuring small displacements by using barberpole sensors producing a cyclical voltage having a mark/space ratio indicative of position
    Patent number: 5142225
    Abstract: An apparatus for measuring small displacements, either linear or angular, employ a pair of spaced "barber pole" or other magnetic field sensitive elements and a movable magnet, in which the exact position of the movable magnet is determined from the voltages sensed at the two elements. The voltages are evaluated in a circuit which produces a rectangular voltage or equivalent, in which the mark/space ratio equates to the position of the magnet between the two sensors.
