Single vs Multifrequency Eddy Current Testing | Zetec MIZ-27 Demo

Описание: Description:
In this video, we use the Zetec MIZ-27 to demonstrate the key differences between single-frequency and multifrequency eddy current testing.

This side-by-side comparison shows how single-frequency inspection can be limited by competing signal variables like geometry and liftoff—while multifrequency techniques allow for signal mixing, subtraction, and noise reduction, enabling better detection and sizing of flaws.

Using a practical test setup, we highlight how multifrequency ECT helps:
• Suppress unwanted signals (e.g., liftoff, coating effects)
• Enhance flaw visibility
• Improve inspection reliability in complex geometries

What You’ll See in This Video:
• Setup and scan using a single frequency
• Transition to a two-frequency mix for improved clarity
• Live impedance plane signals showing real-time differences
• Clear explanation of when and why to use multifrequency setups

The Zetec MIZ-27, though a legacy system, remains a powerful tool for understanding the principles of advanced signal processing in eddy current testing.
