软磁铁心磁性能的自动测试

The automatic test of magnetic performance core of safety valve in gas-fired instrument

介绍了安全阀铁心磁性能测试系统的结构、测量原理。系统软件界面设计。结合实例，对其测试结果以及产生误差的因素作了分析。该系统可实现磁性参数测试过程自动化，已用于安全阀铁心磁性能的研究和产品检验。

This paper introduced that the structure、testing principle and boundary design of the system software for test system of the performance core of security valve. At the measur- ing an actual sample, the testing object and producing factor are analyzed. This system can realize the automatic test of magnetic performance,and has been applied in research of mag- netic performance core of safety valve and inspection of product.
