▶ Operating principle of Hall zero flux current sensor:

Hall zero-flux principle of Hall closed-loop current sensors fundamentally solve the inherent shortcomings of Hall components.

Hall zero-flux current sensor (also known as Hall zero-flux current comparator) is the use of iron core to the magnetic field generated by the bus current aggregation, through the Hall components of the detected magnetic field is converted into a voltage signal, through the amplification of the voltage signal and the current converter output current, so that the current through the wire packet on the role of the poly-magnetic core, so that the wire packet in the core of the magnetic field produced by the bus current in the core produced by the magnetic field of equal size and opposite direction, the iron core, the magnetic field produced by the bus current in the core When the size is equal and the direction is opposite, the magnetic flux in the core is zero, and the number of ampere-turns of the wire package is always equal to the number of ampere-turns on the bus.
