摘要

实现并测试了一种用于低磁场测量的高灵敏度矢量二维磁传感器系统。该系统采用PCB技术实现,由一个双轴磁通门磁传感器及其基于二次谐波检测的前端电子电路组成。采用非晶磁性材料Vitrovac 6025X (25 /spl mu/m厚)和Vitrovac 6025Z (20 /spl mu/m厚)作为传感器的铁磁芯。用Vitrovac 6025Z在10 kHz下施加450 mA的正弦激励电流,磁灵敏度约为1.25 mV//spl mu/T,适合探测地球磁场(/spl plusmn/60 /spl mu/T),满量程线性误差为1.5%。使用较厚的Vitrovac 6025X,在/spl plusmn/60 /spl mu/T范围内获得了最大灵敏度约为1.68 mV//spl mu/T,满量程线性误差约为1.55%,正弦激励电流为600 mA,峰值为10 kHz。所提出的二维矢量传感器系统的特点是由于使用了市售的极薄铁磁材料,因此制作过程非常简单。

Precise vector-2D magnetic field sensor system for electronic compass
An high sensitivity vector-2D magnetic sensor system for low magnetic field measurements has been realized and tested. The system, realized in PCB technology, consists of a double axis fluxgate magnetic sensor with its front-end electronic circuitry based on second-harmonic detection. The amorphous magnetic materials Vitrovac 6025X (25 /spl mu/m thick) and Vitrovac 6025Z (20 /spl mu/m thick) were used as a ferromagnetic core for the sensor. Applying a sinusoidal excitation current of 450 mA peak at 10 kHz with the Vitrovac 6025Z, the magnetic sensitivity was about 1.25 mV//spl mu/T, suitable for detecting the Earth's magnetic field (/spl plusmn/60 /spl mu/T), while the linearity error is 1.5% full scale. Using the thicker Vitrovac 6025X, a maximum sensitivity of about 1.68 mV//spl mu/T and a linearity error of about 1.55% full scale in the range of /spl plusmn/60 /spl mu/T were obtained with a larger sinusoidal excitation current of 600 mA peak at 10 kHz. The 2D vector sensor system presented is characterized by a very simple process fabrication due to the use of commercially available very thin ferromagnetic material.
