YX launches a high-precision open current sensor with independent intellectual property rights, using fluxgate technology. The purpose is to provide an open current sensor to solve the problem of low current detection accuracy of existing open current sensors in the industrial field. The multi-point zero flux technology system is applied to the existing high-precision open current sensor. The excitation flux closed-loop control technology, self-excited flux gate technology and multi-closed-loop control technology are combined to realize the control of excitation flux, DC flux, AC The zero-magnetic flux closed-loop control of the magnetic flux and the detection of high-frequency ripples are achieved by constructing a high-frequency ripple sensing channel, so that the sensor has relatively high gain and measurement accuracy within the full bandwidth range.
