Eddy Current Flaw Detector - QualiECFD-Series

Eddy Current Flaw Detectors are advanced non-destructive testing (NDT) instruments used to detect surface and near-surface defects in conductive materials. These detectors work on the principle of electromagnetic induction, making them ideal for inspecting metals without damaging the component.

How Do Eddy Current Flaw Detectors Work?

An alternating current is passed through a coil, generating an oscillating magnetic field. When this coil is brought near a conductive material, eddy currents are induced in the material. Defects such as cracks, corrosion, or voids disrupt these currents, which alters the impedance of the coil. This change is detected and analyzed to identify flaws in the material.

Key Features of Eddy Current Flaw Detectors

• High sensitivity to small cracks
• Portable and easy to use on-site
• Suitable for complex geometries
• Instantaneous results
• Can detect flaws beneath paint or coatings
