摘要
采用宽频比较仪的电流检测技术,设计了高稳定度和高准确度的电流源,与亥姆霍兹线圈组成了高准确度标准磁场装置,从而实现对磁强计的校准。标准磁场经标定后,上位机软件能自动显示磁通密度,作为标准磁场使用。
Broadband comparator flow detection technology was adopted to design the high stability and high precision current source, and the helmholtz coil of the high accuracy standard magnetic field device, so as to realize the calibration of the magnetometer. After calibration, PC software can automatically display of magnetic induction intensity value, It can be used as a standard magnetic field.
