Abstract
An eddy current probe assembly includes an eddy current probe extending along a center axis between and to a probe end and a distal end. The eddy current probe includes a first drive coil, a second drive coil, a first differential sense coil, and a second differential sense coil. Each of the first drive coil, the second drive coil, the first differential sense coil, and the second differential sense coil is disposed at the probe end and the center axis. The first drive coil, the second drive coil, the first differential sense coil, and the second differential sense coil are arranged circumferentially about the center axis with the first drive coil disposed circumferentially between and circumferentially adjacent the first differential sense coil and the second differential sense coil and the second drive coil disposed circumferentially between and circumferentially adjacent the first differential sense coil and the second differential sense coil.
