交变磁场测量系统中磁传感器的设计

The Theoretical Design Of Magnetic Sensor Applied In Alternative Current Field Measurement System

阐述了交变磁场测量(ACFM)系统中磁场传感器的检测原理,并在此基础上,根据被测磁场的变化特点,设计了一种可实现空间“点”磁场测量的传感器。通过对磁场的实际测量结果和理论计算值的比较,说明该传感器能实现对“点”磁场信号的准确测量。

The principle of magnetic field sensor applied in alternative current field measurement system is intr[(o)0(d)0(u)]ced clearly, and then on the base of it, the theoretical design method of sensor, which can be used to measure 損oint magnetic field, is expound according to distributed characteristic of the magnetic field. Compared experimental measurement with calculation of magnetic field, the result validated that it can accomplish the accurate point measurement of magnetic field.
