摘要
介绍了用光纤作为转速传感探头的转速测量原理，分析了探头作用距离与探头参数之间的关系，给出了一些解决干扰问题的方法，对电路部分作了必要的说明，本系统探头体积小，易于安装，无电火花，抗电磁辐射，具有传统测量方法所不具备的优点。
Introduces the working principle of using optical fiber as the rotation speed measuringsensor probe,and analyzes the relation bet ween the working distance of probe and the parameter ofprobe.Presents some methods of solving the problems of interferenee.The probe of this system issmall in size,easy to be installed,and has no electric sparks and resisting electromagneticdisturbances.
