고정밀 플럭스게이트 전류 센서의 작동 원리:

포지티브 및 네거티브 여기 전류의 작용하에 포화되기 쉬운 자기 코어를 사용하여 여기 전류의 크기에 따라 자기 코어의 인덕턴스를 변경하여 자기 코어의 자속이 지속적으로 변경됩니다.

그만큼 fluxgate current sensor uses the non-linear relationship between the magnetic induction intensity and the magnetic field intensity of the high magnetic permeability core in the measured magnetic field under the saturation excitation of the alternating magnetic field to measure the weak magnetic field. This physical phenomenon seems to be a “gate” to the measured ambient magnetic field. Through this “gate”, the corresponding magnetic flux is modulated and an induced electromotive force is generated. This phenomenon is used to measure the magnetic field generated by the current, so as to indirectly achieve the purpose of measuring the current.
