ELECTROMAGNETIC ULTRASONIC SENSOR MODULE CAPABLE OF IMPROVING THE EFFICIENCY OF ELECTROMAGNETIC ULTRASONIC SIGNALS

摘要

PURPOSE: An electromagnetic ultrasonic sensor module is provided to improve efficiency thereof by increasing the intensity and the resistance of SH-wave electromagnetic ultrasonic signals and to easily perform a pipe inspection using a pipe nondestructive inspection robot.;CONSTITUTION: An electromagnetic ultrasonic sensor module(1) comprises planar structures(10) and meander coils(11). The planar structures are bent according to a grade of a pipe and formed into a comb shape. The meander coils are coiled around the planar structures. The meander coils are arranged in the planar structures at an equal interval. The planar structures are installed in a yoke. The yoke includes a magnet installed to be moved upward and downward in an electromagnetic ultrasonic probe.;COPYRIGHT KIPO 2013
