Abstract

To research the analysis methods about the coil impedance of eddy current sensor

two analysis methods

theoretic method and finite element method

are proposed.The series expression of the coil impedance is introduced.On the basis of analytical calculation

the computational model of the coil impedance is simplified as a cylindrical coil over a cylindrical measured target with the thickness S.The coil impedance value and the magnetic distribution figures are obtained by finite element analysis

respectively.Finally

the results from the derivation and finite element analysis are in agreement very well by comparison.
