Eddy Current Array (ECA)

Eddy current array (ECA) is a non-destructive testing method. for inspecting metal parts An eddy current is an alternating magnetic field created when an alternating current is passed through one or more coils in a probe assembly. When connecting the probe to the part under inspection An alternating magnetic field induces eddy currents in the test segment. Any discontinuity or variation in the properties of the test section will change the eddy current flow. And will be detected by the probe to measure the thickness of the material. Or find material defects such as cracks and corrosion.
