A high-precision current sensor compensates for the magnetic field generated by the primary current with the magnetic field generated by the secondary current, and uses a second magnetic core for noise reduction. The difference is detected by a microcontroller to form an asymmetric flux gate current, which accurately reflects the changes in the primary current. Has very high accuracy and linearity (ppm level), with very low temperature drift. Widely used in medical, high-speed rail, high-end precision instruments, university laboratories, and various testing and calibration institutions.
