摘要(Abstract)：

测量润滑油中微小的铁磁性颗粒是判断机械设备磨损程度和形式的重要手段。利用自主开发传感器、LM324放大器件、TLC549A/D转换器、STC89C52单片机和CH451数码管驱动芯片,通过C语言编程,本文设计了一套基于法拉第电磁感应原理测量铁磁颗粒含量的实验仪器。提出了非介入式铁磁颗粒含量的测量方案。确定了检测信号变化量与铁磨粒含量之间的定量关系。通过对于静态及动态数据的实验采集,确定了检测系统各部分的最优执行参数以及系统的检测精度,实现了铁磁颗粒含量的非接触定量检测。利用该装置可以开展基于电磁感应定律的验证性实验,该实验设备结构简单,可以锻炼学生的动手能力和运用理论知识解决实际问题的能力,非常适合用于大学物理实验教学。
