Title: Eddy current flaw detector
Inventor: MIZUNO MASASHI
IPC: G01N27/90
Filed: 1983-09-30
Abstract: PURPOSE:To make a flaw signal extremely noticeable by arranging two detection parts at a probe, generating two positive and negative signals for one flaw that a material 1 to be inspected has with time difference and delaying the flaw signal by the time difference between the positive and negative signals, and subtracting the signal of a delay circuit from the original signal. CONSTITUTION:Detection coils 9 and 10 wound around magnetic poles 7 and 8 of the probe 6 are connected differentially to each other, and one terminal and the other terminal of those coils are output points 11 for the flaw signal. One terminal and the other terminal of an exciting coil 12 are input points 13 for an exciting signal. The delay circuit 16 outputs the output signal of a phase detection part 15 with prescribed time delay. A subtracting circuit 17 subtracts the output signal of the circuit 16 from the output signal of the detection part 15. At this time, the flaw signal 22 is outputted from the circuit 17 as a signal 22' since the signal from the delay circuit 16 is delayed behind the signal from the detection part 15 by the time DELTAt from the positive signal 22a of the flaw signal 22 to the negative signal 22b.
