摘要

本文介绍了一种基于二次谐波傅立叶分量的磁通门磁传感器的设计、研制和应用。该传感器用于测量外部磁直流或低频交流磁场，Bext。探头被流经预磁化线圈的正弦电流周期性地驱动到饱和状态。结果表明，利用外磁场可以测量二次谐波频率分量的幅值。磁通门传感器的一些应用，如非接触电流测量、振动和位移测量，已经开发和测试。

Fluxgate magnetic sensor

The paper explains design, development, and applications of a fluxgate magnetic sensor, which is based on second harmonic Fourier component. The sensor is used to measure an external magnetic DC or low-frequency AC field, Bext. The probe is driven periodically into saturation by a sinusoidal current that flows through the premagnetization coil. It can be shown that the amplitude of the second harmonic frequency component will be measured by external magnetic field. Some applications of the fluxgate sensor, e.g. non-contact current measurement, vibrations and displacement measurements, have been developed and tested.
