High-precision AC and DC Hall current sensors

The sensor works on the principle of magnetically balanced Hall voltage detection. The magnetic flux generated by the primary current is in balance with the secondary voltage generated by the Hall voltage amplification, and the magnetic flux generated by the secondary coil is balanced, and the secondary voltage can accurately reflect the primary current.
