Abstract :
An instrument for non-destructive testing in industrial environment was designed, realized and tested. It uses fluxset magnetic sensors and is based on dedicated boards suitably realized for optimizing system performances without loosing in flexibility. A self-calibration and adjustment capability was implemented thus allowing a system optimum operating in any different environment. FFT based algorithm was used for both probe adjustment and measurement post-processing. The realized instrument has then been tested on specimen with known cracks and the experimental results have been compared with the theoretical ones showing a very good agreement.
