Abstract: Eddy current sensor has high sensitivity, high linearity, simple structure, wide range of linear measurement, non-contact measurement, and can work continuously in harsh environment such as oil, gas and water. It is widely used in on-line detection of displacement, eccentricity and rotational speed in industrial production. At present, the research on eddy current sensor focuses on the mechanism of electromagnetism model and the improvement of measurement accuracy. This paper briefly describes the working principle of eddy current sensor, the technical performance index of imported eddy current sensor, discusses the measurement parameters of eddy current sensor on turbine generator set, determines the method, and puts forward preventive measures for the problems of sensor installation.
