Magnafield AC Electromagnetic Yoke | 230V 50/60-Hz
Portable, High-Performance Surface Crack Detection
The Magnafield AC Yoke is a rugged, handheld electromagnetic induction device designed for the rapid detection of surface-breaking discontinuities in ferromagnetic materials. Engineered to withstand the rigors of field use in oil & gas, shipbuilding, and structural fabrication, this 230V model is specifically configured for international power standards. Its articulating legs allow for precise contact on complex geometries, ensuring a consistent magnetic field for reliable flaw detection.
High Lifting Power: Engineered to exceed the standard lift test requirements, providing a powerful AC magnetic field to reveal tight fatigue cracks and stress corrosion.
Articulating Double-Jointed Legs: The legs adjust easily to any contour, making it possible to inspect pipe welds, inside corners, and irregular castings with 100% contact.
Ergonomic Trigger Design: Features a heavy-duty, moisture-sealed switch designed for ease of use even while wearing thick welding or safety gloves.
230V Global Compatibility: Optimized for 230V 50/60-Hz operation, making it ideal for offshore rigs, international shipyards, and European or Middle Eastern infrastructure projects.
Field-Replaceable Components: Designed for easy maintenance, including a replaceable power cord and switch assembly to minimize downtime in the field.
