NON-DESTRUCTIVE INSPECTION DEVICE FOR PRESSURE CONTAINERS USING LEAKAGE-FLUX MEASUREMENT

摘要

According to one embodiment of the present invention, a non-destructive inspection device for pressure containers using leakage-flux measurement comprises: a coil winding mount which is provided on one side on the outside of a pressure container and magnetises the pressure container; a sensor support which is provided on the other side on the outside of the pressure container, and on which are disposed a plurality of magnetic-field sensing sensors; a yoke which magnetises the pressure container and generates a magnetic flux in a direction perpendicular to the direction of the magnetic flux generated by the coil winding mount; and an endoscope to which one or more magnetic-field sensing sensor(s) is (are) attached.
