MAC will be showcasing its advanced eddy current testing solutions, including compact systems designed for inline testing of both ferrous and non-ferrous materials. Whether you need high-speed flaw detection or precision testing for dimensional or material differences, our systems deliver reliable results with full digital capability.
Troy M. Libby, Senior Applications Engineer at MAC, will lead a technical session on the fundamentals of eddy current testing using coils and stationary probes.
He will break down how key factors—such as material type, product size, and defect characteristics—determine whether to use absolute mode with a single coil, or differential mode with multiple coil windings. He’ll also cover how some systems can operate in both modes simultaneously, providing enhanced sensitivity and more comprehensive defect detection.
