Digital Capacitive Micrometer and Its Accuracy Improving

This paper introduced a new type micro-displacement measurement instrument which has a high accuracy, called "digital capacitive micrometer". It can be used for the precision measurement of workpiece shape error and dimensions parameters and the dynamic tast of mechanical vibration and shock. Based on error analysis, improved methods are given for higher accuracy in the paper. Theoretical analysis and experiment show that the improving measures are effective.
