EDDY CURRENT FLAW DETECTION PROBE

摘要

PROBLEM TO BE SOLVED: To accurately detect a flaw in an eddy current flaw detection probe. SOLUTION: This probe for detecting the flaw in a test body 10 has plural excitation coils 22a-22h generating an AC magnetic field to generate an eddy current in the test body 10, and plural thin film-like detection coils 21a-21h overlapped in an upper-and-lower double-layer state and arranged in a line.
