Abstract

In order to properly reflect the characteristics of numeral eddy current sensor, this paper begins with an introduction of its working principles, and the characteristic relationship(d, f) between the displacement amount of tested specimens and the output frequency of relative measuring circuits is also described. Then a mathematical modeling approach of numeral eddy current sensor relation feature(d, f) is proposed based on the basic principles of least squares estimation algorithm via the language of MATLAB, and the modeling program flowchart and the simulation results are provided as well.
