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.

Matters needing attention:

  • When running normally, the green light is always on. When the equipment is powered on, when the equipment is working normally, the green indicator lights are always on, and the third and eighth legs of the D-Sub9 interface are on.

  • When the current is overloaded or the power supply is abnormal, the green light goes out. When the green light is not on, the power supply of the sensor should be checked first.

  • Under the normal condition of power supply, if the green indicator lights out, the current sensor is in non-zero flux state. At this time, if the bus bar input current exceeds the specified range of the sensor, the sensor  enters the overload mode, and the output current is no longer proportional to the input current signal.

  • The input current amplitude exceeds the prescribed range of the sensor. The sensor enters the overload mode, and the output current is no longer proportional to the input current signal.When the input current exceeds the specified range of the sensor, the sensor enters the overload mode and the output current is no longer connected with the input current signal.

  • In the overload mode, the output current of the sensor is kept in the maximum output state, and the green indicator is turned off. When input current After restoring to the specified current range, the output current of  the sensor returns to normal and the green indicator is always on.
