ABSTRACT:
A ferromagnetic eddy current probe apparatus having a double shielded magnetic coil to reduce the size of the magnetic filed and to generate a sharply focused electromagnetic field. A ferromagnetic steel alloy provides a double shield effect for greater concentration of the electromagnetic field onto a test specimen, and also to prevent probe tip wear and deformation when used to inspect fastener holes with a high speed designed feature maintenance the size setting of the probe (coil-end) diameter. An expansion slot in the end of the probe provides a spring action during probe radiation to keep a constant contact with the wall of a fastener hole. The ferromagnetic probe portion is removeable from the shank-end (a non-metallic portion of the probe) for easy repair or replacement and provides electrical isolation to prevent shorting of the signal.
