Leak magnetism detection sensor for magnetic flaw detection system |
摘要 |
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.
