MEWOI-MIT10-（0A-1A） (DC) φ26mm highly stabilized and precise fluxgate technology based leakage current transducer/Residual current transducer
INTRODUCTION
| The multi-point zero-flux technology system applied in this high-precision DC transducer combines closed-loop excitation flux control technology, self-excited flux gate technology, and multiple closed loop control technology. The combination of technologies enables zero-flux closed-loop control of excitation flux, DC flux and AC flux, and can detect high-frequency ripple by constructing a high-frequency ripple sensing channel, so that the transducer can achieve high gains and measuring accuracy over the full bandwidth. |
