测试传感器磁灵敏度的一种新方法

A New Method for Testing the Magnetic Field Sensitivity of a Pick-up

本文提出一种测试传感器磁灵敏度的新方法。该方法不必旋转传感器,待测传感器置于旋转磁场中,与周围环境隔离。此时传感器的输出信号是磁场引起的输出信号,从而消除了机械振动及噪声的影响。文中还给出用该方法测试一些传感器的测量结果。

A new method for testing the magnetic field sensitivity of a pickup without any need of its rotation is described in this paper.In this method,a pick-up is located in a rotary magnetic field and statically isolated from the environments.In this way,the output of the pick-up is a pure signal caused only by the rotary magnetic field,and the effects caused by the mechanical vibration,noise etc.can be eliminated.The measurement results of some pick-ups using this method are given.
