摘　　要：介绍了一种新型差动电容式传感器及其构成的控制系统。这种传感器由两片固定金属极板和一片可动极板形成差动式电容结构,在微小偏移作用下,通过动极板引起极板之间电容参数值的变化,进而实现对卷绕机微小偏移量的测量和控制。该控制系统结构简单,反应迅速,能够较好地应用于卷绕机纠偏装置中。This paper presents the application of differential capacitance sensors to the measurement and control of offset in a winding machine. The sensor consists of two static metallic electrodes and one moving electrode, thus forming a differential capacitance. The value of an electric parameter is determined by the offset of the winding machine, so its offset can be measured and controlled. This system is simple in structure, short in response and applicable to the offset guide of a winding machine.
