Abstract
A current sensor includes a two-piece ferromagnetic core clamped together over a wire to be measured by a housing to form a ferromagnetic cylinder that concentrates the magnetic flux surrounding the electrical wire to be measured. By directing the magnetic flux to a Hall effect sensor, the current can be measured in the wire without cutting or modifying the wire.
