Abstract
To study eddy current problem of impedance of eddy current sensor coil moving in transverse direction to conductor,this paper deduces the formula of the impedance and the impedance change in the Cartesian coordinate system when the relative position of coil and conductor is changed,based on second order vector potential.Three-dimensional eddy current model of ECS electromagnetic field are derived based on theabove work,and it is verified by experiments.Using Mathematice to build model,the effect of coil geometry(inside diameter,thickness,line width,line spacing)on the sensitivity and linear measurement range of ECS.Theconclusionsfrom the study provide are ference fordeter mining thecoil shapeparameters and optimizing the per for manceof ECS.关键词
