This study proposes a 2-D bobbin-type magnetic field vector camera in nondestructive testing for inspection of corrosions in inner and outer diameter (ID and OD) of a small-bore piping system. 16.1 mm diameter bobbin probe was produced by integrated of 71 Hall sensors (BIHaS) and 71 Giant magnetoresistance sensors (BIGiS) in two circumferential lines at interval of 0.6 mm. The BIHaS and BIGiS could measure radial and axial components of alternating magnetic field. Thus ID and OD corrosions… CONTINUE READING
