摘要
介绍一种磁阻式非接触角度传感器,可应用于电子油门系统中的油门踏板传感器和节流阀开度传感器。磁阻式传感器通过改变磁钢与磁阻元件的相对位置来改变阻值大小,从而将踏板的线位移信号或角度变化量转化成电压信号输出,以确定油门踏板的位置,实现对节流阀的调节,具有非接触式、成本低的优点。
A non-contact magnetoresistive sensor for angle measuring is introduced. It can be used accelerator pedal sensor and throttle sensor in electronic accelerograph. Magnetoresistive sensor changes the resistance by changing the position of the alnico and the magnetoresistance element, converts the signal of the displacement or change of angle into voltage output, to ensure the position of accelerator pedal and realize the control of the throttle. Its has the properties of non-contact and low cost
