Eddy current array probe design
WebAn Eddy Current Array (ECA), in its fundamental form, is a series of single coils arranged in a row or rows, allowing much larger single-pass coverage than a conventional single-coil eddy current probe. Because of the larger coverage, inspection times are significantly improved. Multiplexing is used to enable/disable the coils in a specific sequence. WebAn Eddy Current Array (ECA), in its fundamental form, is a series of single coils arranged in a row or rows, allowing much larger single-pass coverage than a conventional single …
