  • Ammeter with improved current sensing
    Patent number: 8212549
    Abstract: An ammeter is provided with a plurality of individual wound coils interconnected in a generally U-shaped array to measure the magnitude of current in a conductor extending through a sensing region inside the U-shape. Additional pairs of position-sensing coils determine the position of the conductor relative to the sensing region and provide outputs to circuitry which permits the magnitude measurement to be displayed only if the conductor extends through the sensing region.
    Type: Grant

    Date of Patent: July 3, 2012
    Assignee: HD Electric Company
    Inventors: William J. McNulty, James S. Buchanan, Connor M. McNulty
