Using the finite element analysis software of ANSYS to simulation analyze on multi-layered conductive structure thickness measurement sensor. Simulate better physical model in theory as well as excitation frequency

excitation parameters such as voltage

coil number of turns. In cases of parameters such as frequency

coil number of turns are determined

by changing thickness

simulate corresponding relation of the measured body thickness and excitation voltage

fitting out corresponding formula

verify the correctness of the simulation through instrument.
