Tian, Gui Yun and Sophian, Ali (2005) Study of magnetic sensors for pulsed eddy current techniques. Insight, 47 (5). pp. 277-279. ISSN 1354-2575

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 analysed are sensitivity, noise level, and operational bandwidth. Conclusions are given following the analysis of the data
