Electromagnetic Technologies for Surface Inspections

Eddy Current Array (ECA) is a natural extension of Eddy Current Testing (ECT) that improves on ECT technology by using multiplexed arrays of coils arranged in rows (instead of one or two coils). ECA can cover larger areas much faster and with greater sensitivity than ECT, using single scan passing to detect surface-breaking cracks as small as 0.5mm and sub-surface defects to a penetration depth of 6mm or more.
