Detailed Overview

An AC electromagnetic yoke available in 220VAC electrical formats common in international industrial settings. The design is lightweight and ergonomic to reduce operator fatigue.

It is used to induce a strong, alternating magnetic field to detect and define surface-breaking and near surface flaws using dry magnetic powder or black / fluorescent magnetic ink.

AC-powered electromagnetic yoke with articulating legs for conforming to irregular surfaces providing a powerful, flexible, and essential non-destructive testing (NDT) solution.

Top Features & Benefits

• Works off mains AC Power using 220VAC.
• Adjustable poles to maximize contact on complex or irregular surfaces,
• Meets ASTM E709/E1444 and EN-ISO 9934-3 standards.
• Moulded body protects against impact and provides good resistance to dirt and chemical ingress
• Field-swappable power cord makes for easy repairs and maintenance
• Can be used for simple AC demagnetization of small, localized areas.

Primary Uses & Functions

Primarily used to induce a strong, localized magnetic field in a ferromagnetic component to detect and define surface-breaking discontinuities.

Real-World Applications

Commonly used for inspecting welds, pressure vessels, castings, and forgings for surface defects.
