Li Xinxin, Li Jun . A New Capacitive Sensor-by the Principle of Fringe-field[J]. Editorial Office of Optics and Precision Engineering, 1994,(1): 49-53DOI:
A new capacitlve sensor is given in this paper.Unlike the traditional parallel-plate capacitive sensor
it is a measuring instrument with the large measuring scale and high accuracy
based on the principle of fringe-field.It is well-suited for applications in automatic manufacturing and in-process measurements with the prop-erties of fast response
rugged construction and small size.In this paper
we give the detail description of the principle of measuring method
mathematical deduction and experiments. Experimental results show that this fringe-field capacitive sensor has a wide area of applications.
