本文总结了我们研究成功的一种用磁敏二极管与磁钢组成的新型传感器——磁敏多功能固态传感器。其功能较多,归纳起来可分两类:一类是用来做输出脉冲信号的传感器,如测量转速与线速度等。另一类是用来做输出连续信号的传感器,如测量小线位移、小角位移与无接触发讯器等。本文建立了这种传感器各种功能的测量原理,并用回归分析方法求出它在各种典型工作状态下的特性方程式(经验公式)。 This article summarizes our successful study of a magnetoresistive diode and magnet composed of a new type of sensor - magnetic multi-purpose solid-state sensor. Its more features, can be summed up in two categories: one is used to do the output pulse signal sensor, such as measuring speed and line speed. The other is used to do the output of continuous signal sensors, such as measuring small line displacement, small angular displacement and contactless transmitter. In this paper, the measurement principle of various functions of this sensor is established, and its characteristic equation (empirical formula) under various typical working conditions is obtained by regression analysis method.
