HANGZHI AIT-series high-precision current transducer has a high gain and measurement accuracy in the full bandwidth range, due to the application of the multi-point zero-flux technology system and 

high-frequency ripple sensing channel on top of currently existing DC sensor technology.The multi-point zero-flux technology system secures the high accuracy by utilizing the technology combination of exciting magnetic flux closed-loop control, self-excited magnetic flux gate and multi-closed-loop control that realizes the closed-loop control between excitation magnetic flux and AC/DC magnetic flux generated by primary current, while the high-frequency ripple sensing channel allows the sensor to have the high performance over the full bandwidth range.
