Eddy current array (ECA) technology has long been used for nondestructive testing in aerospace, power generation, oil and gas, and other industrial applications. It’s a fast, accurate, chemical-free method for detecting surface and sub-surface indications including cracks, pits, corrosion, and damage due to temperature or fatigue.
ECA has the added benefit of generating an electronic inspection record for advanced analysis and reporting, a big advantage over dye penetrant testing (PT), magnetic particle testing (MT), and other types of manual examinations. Unlike PT or MT, ECA results can be saved, shared, stored, processed, and compared at any time. Indeed, with the right surface array probe, software, and handheld eddy current instrument, an operator can set up an inspection quickly, capture more information in a single pass, see results instantly on a C-scan display, and dramatically increase the speed, accuracy, and repeatability of the test.
