Eddy Current Array (ECA) Probes

An 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. UniWest’s RCAT array probes feature a miniature multiplexer built right into the probe.

Below are examples of “basic” ECA probes, but as you can imagine, most applications demand a somewhat custom probe to accommodate specific part geometry and required coverage demands. Please contact our ECA experts to discuss your specific application.

Advantages compared to conventional ETC probes

  • Larger single-pass coverage

  • Faster inspection times

  • C-scan imaging & encoding improves flaw detection and visualization

  • Complex shapes can be efficiently inspected using custom probes matching the part profile
