| Abstract: | Giant magneto-resistance (GMR) sensor is a kind of new magnetic field sensor. Compared to most conventional sensors, GMR sensor has the advantages of high sensitivity, high reliability and good integration capability. The principle of GMR sensor and its application to eddy current testing(ECT) was presented. The sample showed that GMR sensor based ECT system was able to achieve good inspection result. |
