资料介绍

磁通门传感器是目前微弱磁场检测中较为理想的测试元件,具有高灵敏度、高精度和良好的稳定性等优点;在分析了三端式磁通门传感器的数学模型的基础上,介绍了其工作原理,即需要激励源、传感器和检测电路共同作用才可以构成完整的测量系统;同时,设计了一种三端式磁通门传感器的激磁电路,其激励电压幅值为5V,频率为5kHz;结果表明,该信号频率和幅值比较稳定,可以作为磁通门传感器的激磁信号。

The magnetic flux gate sensor is the most ideal weak-magnetic fields detection test components currently,it has there advantages such as the high sensitivity,high precision and good stability.This paper analyzes mathematical model of the fluxgate sensor with three tips.On this basis,it also analyzes the working principle that need to motivate source,sensors and detection circuit to form a complete measuring system.Meanwhile,design a kind of excitation circuitry for fluxgate sensor with three tips,the excitation voltage amplitude is 5V and the Frequency is 5kHz.Results show that the signal frequency and amplitude is stable,can serve as the excitation signal for fluxgate sensor.
