Abstract
In accordance with the present invention there is provided an eddy current probe for the detection of defects within a structure. The probe has a sensing end with a coil disposed therein. The coil is operative to generate an eddy current field within the structure when placed adjacent to the structure. Furthermore, the probe of the present invention includes a metallic shield disposed around the coil and operative to focus the eddy current field within the structure. In order to generate the eddy current field, the coil is in electrical communication with a frequency generator. The frequency generator is operative to generate a high and low frequency signal within the coil in order to enhance detection of defects within the structure.
Claims9
An eddy current probe adapted to detect defects within a plurality of differently sized fastener holes, the probe comprising:
- a sensing end operative to generate an eddy current field within the plurality of differently sized fastener holes, the sensing end forming a slit therein;
- an adjustment shaft engaged to the sensing end;
- and
- an adjustment sleeve movably engaged to the adjustment shaft and extendable to the sensing end, the adjustment sleeve being configured to adjust the sensing end when extended thereto via constriction of the slit formed therein so as to correspond the sensing end to the plurality of differently sized fastener holes.
