Segmentation Type Capacitance Sensor and Its Application

During the crude oil produces in the oil field, measuring of the oil-water interface has been a key technology and difficult problem all the time. The author has designed a kind of new-type segmentation type capacitance sensor on the basis of the traditional capacitance sensor principle, which has well solved this difficult problem. Because of its high precision, simple principle and structure, and the cheap price, this sensor has very good application in prospect.
