摘　　要：介绍一种磁粉检测用晶闸管控制电路的磁化电流测量方法 ,利用该方法开发一种磁粉探伤用计算机控制器 ,实际使用表明 ,其电流控制稳定性符合我国常用磁粉检测标准要求 ,断电相位控制可靠。A method for measuring the magnetization current of magnetic particle testing controlled by SCR (silicon controlled rectifier) was introduced. A micro computer controller was developed. It was proved by practical application that the stability of the controller satisfied the commonly used magnetic particle testing standard of China and the current cut down phase control was reliable.
