Patent ID: 7528599

Claim:
An eddy current probe for analyzing tubular specimens, the eddy current probe comprising: an annular core defining an outer surface and an axis; a first coil conductor wound about the annular core to define a first plurality of winding sections spaced about the annular core and disposed at an acute angle relative to the axis, the first coil conductor being configured for detecting changes in the flow of eddy currents in a tubular specimen; and a second coil conductor wound about the annular core to define a second plurality of winding sections spaced about the annular core and disposed at an acute angle relative to the axis of between 22.5 degrees and 67.5 degrees, the second coil conductor is configured for detecting changes in the flow of eddy currents in the tubular specimen; wherein the first plurality of winding sections are disposed at the same axial position as the second plurality of winding sections.
