Title: Comparison of Selected Multifrequency Eddy Current Systems

Abstract

In this paper, authors take into consideration two different implementations of the multifrequency EC method. In the first implementation, the excitation coils are powered by a programmable generator with a signal consisting selected sinusoidal components. An output signal from detection coils is analyzed using Fourier transform in order to obtain amplitudes of all the components. In the second method, the sensor is excited by sinusoidal signal with modulated frequency. For both implementations, the authors analyze various measurement conditions and compare the results obtained for Incone1600 plate.
