Patent attributes
A current sensor includes a ferromagnetic core having a substantially central opening for receiving a current conductor and a gap. A detector of the current sensor includes at least one first magnetic field sensing element disposed in a first gap portion and configured to generate a respective first magnetic field signal in response to a first magnetic field having a first angle with respect to the at least one first magnetic field sensing element. The detector also includes at least one second magnetic field sensing element disposed in a second gap portion and configured to generate a respective second magnetic field signal in response to a second magnetic field having a second angle with respect to the at least one second magnetic field sensing element. The first and second magnetic fields are substantially equal in magnitude and the first and second angles are substantially opposite in polarity.
