Title:
COMPLEX NONDESTRUCTIVE INSPECTION DEVICE USING A HYBRID INDUCTIVE MAGNETIC THIN FILM SENSOR
Document Type and Number:
WIPO Patent Application WO/2011/138993
Kind Code:
A1
Abstract:
The present invention relates to a complex nondestructive inspection device using a hybrid inductive magnetic thin film sensor. In more detail, the complex nondestructive inspection device induces inductive magnetic flux into an item to be inspected by applying an AC magnetic field to an excitation coil, and simultaneously magnetizes the item to be inspected using a permanent magnet, in order to detect a change in the magnetic flux induced into the item to be inspected as well as leakage flux using a coil unit coiled into a sensor core in a thin film sensor. Therefore, the extent of defects in the item to be inspected may be quantitatively inspected, and also the defects may be detected by means of simple manipulation and not professional manipulation. Furthermore, by means of only a single inspection, all defects on the surface, back, inside, and outside of the item to be inspected are detected, and the item to be inspected may be evaluated regardless of whether the item to be inspected includes a magnetic material or a non-magnetic material.
