Eddy current testers are based on the detection of variations in the electrical conductivity and magnetic permeability of a metal surface. It is commonly used in manufacturing to inspect thin metal ...

Eddy current testing (ECT) is a widely adopted non-destructive evaluation (NDE) method that leverages electromagnetic induction to detect and characterise defects in conductive materials. By inducing ...

John Hansen, Managing Director/CEO of Ether NDE Ltd, talks to AZoM about Eddy Current Testing. What is an Eddy Current NDT? Eddy Current Testing is one of the many Non-destructive Testing (NDT) ...

The Uni-Versal test machine is based on multi-channel eddy-current testing instrument with up to eight channels, a frequency range of 20 Hz to 10 Mz; a 12-in. LCD flat-panel screen; and 32 Gig of data ...

Eddy current testing has been used for at least 50 years to inspect conductive parts for surface imperfections such as cracks or scratches. Fundamentally, the technique is comparative—it only ...
