Eddy Current Testing Equipment FAQs

How does eddy current measurement work?

Eddy current testing is a nondestructive testing (NDT) method that can be used for various inspection and detection applications. Eddy current inspections work using an electromagnetic field to measure the response from a material. Eddy current testing equipment generates magnetic fields, which induce a current that flows in a test piece (e.g., a conductor such as a coil). This influences the magnetic field, as well as the magnitude and phase of voltage in the coil. Any changes in conductivity, such as defects or thickness differences, can affect the resulting eddy current. This technology can then be used to measure distance or to detect flaws in conducting materials such as corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks.
