Latest Patents

One of Randall H. Field's notable patents is the "Dual eddy current probe for detecting geometrical differences especially as related to threaded apertures and studs." This invention provides an apparatus and method for inspecting contours formed along a predetermined region of a surface on a workpiece made of electrically conductive material using eddy current technology. The probe is designed to move along a path of travel with respect to the predetermined region to be inspected. It features at least two coils that are spaced longitudinally and electrically excited with a predetermined frequency and amplitude during the probe's movement. Sensors measure the excitation voltage of each coil as eddy currents are induced in the workpiece, allowing for a comparison of the measured eddy current signals. A non-zero difference after the coils have encountered the predetermined region indicates the end position of the region being tested.
