摘要
为解决长期制约我国电磁法勘探技术发展的感应式频率域磁传感器研制问题,以法拉第电磁感应定律为基础,通过对磁芯材料研制、感应线圈绕制、输出信号的开环补偿以及电场干扰信号的梳状屏蔽技术的研究,总结出传感器研制调试方法,并成功研制感应式频率域磁传感器。测试与试验结果表明,该传感器具有在3~10 000 Hz的工作频带内幅频特性曲线平坦的特点,实测结果与进口传感器相当。满足物探电磁法测量需要。
In order to solve the problems of magnetic sensor research that restrict electromagnetic method exploration technique development for a long time,base on Faraday law on electromagnetic induction, Research of magnetic core production,producting induction coils,open-loop compensation of output signal and comb shielding of electric signal ,Giving the methods of debugging magnetic field sensor .The amplitude frequency characteristics curve of magnetic field sensor is flat in the working band of 3-10 000 Hz. The measured results is similar between this one and imported sensor.
