为研制一种高精度、360°大角度的电容式角度传感器,文章介绍了一种利用平行板电容器原理设计的角度传感器。当角度发生变化时,利用气体和电介质液体与多个电极间面积的变化,导致相应的电容发生了变化。经实验验证,利用这个原理设计的角度传感器具有较高的线性度和分辨率,并在一定程度上可以消除温度对传感器的影响。 In order to develop a high-precision, 360 ° wide-angle capacitive angle sensor, an article describes an angle sensor designed using the principle of parallel plate capacitors. When the angle changes, the change of the area between the gas and the dielectric liquid and the plurality of electrodes takes place, resulting in a change in the corresponding capacitance. The experimental verification shows that the angle sensor designed by using this principle has high linearity and resolution, and to a certain extent, can eliminate the influence of temperature on the sensor.
