摘要
为测绘软磁材料超微晶的磁导率曲线,采用电流电压法对其进行测量,并对测量系统及方法进行优化改进,设计上位机软件,采用标准RS232通信接口,实现对测试仪器的自动控制及测量数据的实时记录,最终描绘出磁导率随交流磁场强度变化的曲线。结果表明:该方法能准确测出初始磁导率和最大磁导率,其测绘结果与厂家数据手册基本相符,有一定的工程利用价值。
In order to describe the permeability curve of soft magnetic material ultra crystallite, the current voltage meter is used to measure, and optimize the system and method of measurement, the instrument＇s automatic controlling and the data＇s real-time recording are realized through standard RS232 communication interface. Finally map the permeability variation curve by influence of AC magnetic field intensity. The result shows that the method can accurately measure the initial and maximum permeability. The result conforms to the data sheet, which has a certain engineering value in use.
