  • Magneto resistive current sensor with improved fidelity
    Patent number: 4857837
    Abstract: The present invention is a current sensor employing a magneto resistive sensor having high fidelity of output. This current sensor includes a magnetic flux concentrator substantially encircling the electrical conductor having magnetic sensing, a magnetic device generating a magnetic field component along an axis offset from the principle axis, a magneto resistive device disposed in the magnetic sensing region, a constant current source supplying a predetermined constant current to said magneto resistive device, and a voltage sensing circuit connected to said magneto resistive device for measuring resistance by measuring a difference voltage induced by said constant current. This measured voltage corresponds to the current through the conductor. The magneto resistive device is formed as a Wheatstone bridge having a first and second pair of opposite terminals.
