Abstract
A non-contact DC current sensor has a housing in which a pair of cantilevered compliant armatures are mounted. In one embodiment, a single magnet is mounted to a free end of one armature portion, and a nonmagnetic mass of the same moment and weight is mounted at the free end of the other armature to compensate for gravitational forces. Strain gages are mounted adjacent the magnet and the nonmagnetic mass on the pair of armatures. The strain gages are connected in a circuit to generate an output caused by a Lorentz force. The circuit includes provision for static gravity compensation, and in one embodiment l/r compensation.
