Open Loop Current Sensors

Open loop current sensors are developed on base of hall effect open loop principle. When measured current flowing through a wire, magnetic field is generated around the wire. It’s proportional to the primary current and measured by the hall element in the gap of magnetic core. The sensors provide an output voltage after signal amplification. The output voltage can accurately reflect the measured current.
