Description	This paper describes the measuring interface to be included in an automated microcomputer based Eddy Current Testing (ECT) system developed to characterize structural flaws inside electrically conducting nonmagnetic plates. The principle of operation is based on the measurement of the output voltages of two sensing coils. A description of the implemented prototype using two different types of probes including the digital signal processing used to overcome the signal degradation is presented. The application of a 2D Finite Element Method (FEM) allows to preview the range of the resulting output voltages in the detection coils and also the excitation current amplitude necessary to obtain a given signal to noise ratio. The experimental results obtained with the two probes are presented and one may conclude by inspection that the quality of the obtained data and the amount of information required for future structural defects characterization depend greatly on the probe geometry.
