Abstract:  In this study we compare the suitability of a Hall device and a GMR 
sensor as the sensing device in pulsed eddy current systems. The comparative 
study is carried out by using both experimental results and manufacturers' data. 
The factors to be analysed are sensitivity, noise level, and operational 
bandwidth. Conclusions are given following the analysis of the data.
Keywords: Pulsed Eddy Current NDT, magnetic sensors
