  • High sensitivity saturable core magnetic field sensor with symmetrical structure
    Patent number: 5168223
    Abstract: A high sensitivity magnetic field sensor comprises a high permeability magnetic circuit (10) and excitation means (L.sub.e) for periodically saturating the magnetic circuit. Two identical windings (L.sub.1, L.sub.2) are symmetrically wound around symmetrical parts (A, B) of the magnetic circuit. Identical first and second capacitors (C.sub.1, C.sub.2) are respectively connected to the terminals of the windings. The voltages on the windings determine the value of the magnetic field.
