Title:
NONDESTRUCTIVE INSPECTION APPARATUS USING A FERROMAGNETIC BAR
Document Type and Number:
WIPO Patent Application WO/2011/055901
Kind Code:
A1
Abstract:
According to the present invention, a nondestructive inspection apparatus comprises: a magnetic sensor; a ferromagnetic bar, a signal processor, and a display. The magnetic sensor generates a magnetic field sensing signal corresponding to the magnetic field intensity of an object for inspection. The ferromagnetic bar is installed between the object for inspection and the magnetic sensor. The signal processor converts the magnetic field sensing signal from the magnetic sensor into a displayable format. The display displays the magnetic field sensing signal from the signal processor.
