  • Leak magnetism detection sensor for magnetic flaw detection system
    Patent number: 6774627
    Abstract: A soft-magnetic material is installed on the opposite side of the magnetism sensing face of magnetism sensing devices. This soft-magnetic material is larger than the magnetism sensing face. Then the detection coverage per sensor is enlarged, and the number of sensors and signal processing circuits are reduced across the width of the strip.
    Type: Grant
    Filed: August 26, 2002
    Date of Patent: August 10, 2004
    Assignees: Kawasaki Steel Corporation, System Hitec, Ltd.
    Inventors: Hiroyuki Yokota, Yasuo Tomura, Hideaki Unzaki, Shigetoshi Tsuruoka
