【Abstract】 The capacitive grating sensor is high precision in length measurement.Excepting to be used to digital display vernier calipers,it is also can be used to more extensive detection fields,and as a results,it will largely lower test cost and enhance test precision.This paper introduced an approach to measure the mechanical movement track by capacitive grating sensor.The principle and the data format of capacitive sensor,the composing of this application system and some primary circuit module were analysed in detail,especially the data output from the capacitive sensor and the design of the interface of transmission.The value of the approach is well proved by experiment and its application in industrial production.更多还原
