摘　　要：研究钴基非晶态合金条带制成的单磁芯双绕组新型磁场传感器.采用频率测量方法测量磁场,提高了传感器的测量灵敏度;采用闭环测量系统,增加了传感器的稳定度.A new single-core and double-winding magnetic field sensor prepared from Co-based amorphous ribbon was studied. Using frequency measurement approach to measuring magnetic fields increases the measurement sensitivity of the sensor. Using the closed-loop system increases the stability of the sensor.

关 键 词：闭环系统 单磁芯双绕阻 非晶合金带 频率测量
