Hall Current Sensors – Closed Loop

The Hall Current sensors measure the magnetic field surrounding the conductor (also sensing DC currents). A circular core of soft magnetic material is placed around the conductor to concentrate the field. The Hall element, which is placed in a small air gap, delivers a voltage that is proportional to the measured current.

Closed-loop Hall sensors are more accurate than Open Loop Current Sensors. The Hall voltage is first significantly amplified, and the amplifier’s output current then flows through a compensation circular path on the magnetic core. It generates a counter magnetization whose amplitude is equal in opposite direction to that of the primary current conductor. As a result the magnetic flux in the core is compensated to zero.
