Article Preview

In order to meet the demands for high precise micro-displacement testing, a differential capacitive displacement sensor based on RC multi-oscillating circuit was designed. It has two couples of polar plates, and gets the displacement by testing frequency through the multi-oscillating circuit. This capacitive sensor has many advantages such as simple structure and testing circuit, high resolution and good stability.
