The purpose of this paper is to compare performances of various sensing elements in eddy current non-destructive inspection. A new eddy current testing probe is designed to compare detection and resolution capabilities of different sensors. Four magnetic sensors, specifically GMR (1D and 3D- sensor), AMR, Fluxgate, and a standard induction coil are used as a sensing element. For comparison of these sensors the numerical simulations and experimental measurements are performed under the same conditions. The results are presented and discussed in the paper.
