Experimental Investigation of Static Characteristics on Eddy Current Sensor for External Cylindrical Grinding Measurement System

摘要

In order to investigate the static characteristics of eddy current sensor (ECS) influenced by cylindrical diameter, material and displacement of the target workpiece, some experiments were carried out. Firstly, the theoretical principles of ECS were recalled for explaining the related parameters. The experiment setup was then introduced and some features including linearity, resolution and sensitivity were tested by the experimental instrument and calibrated. Finally, the experimental results were obtained and the influence elements were discussed in the paper.
