With its compact design, efficient layout, lightweight build, and easy portability, this AC/DC Magnetic Particle Yoke – MPI Yokes is ideal for identifying surface and near-surface defects in ferromagnetic materials. It is widely applicable across industries such as power generation, metallurgy, petrochemicals, and manufacturing, and is well-suited for use on boilers, pressure vessels, pipelines, and various welded structures.
The device can operate directly on AC power and also supports both AC and DC magnetization power sources for flexible, efficient use. It is particularly effective for inspecting welds on ship hulls, elevated steel structures, and the interior surfaces of pressure vessels.
Two Operating Modes
The probe can be connected directly to a 110V AC power source for alternating current testing. Battery operation is also available as an alternative.
Adjustable Pole Spacing
The probe accommodates a wide range of workpieces, with an adjustable pole distance from 0 mm up to 200 mm for flexible and accurate flaw detection.
Three Power Supply Options
Compatible with single-phase AC power, AC magnetization power, and DC magnetization power. Users can freely select the power source that best suits their inspection needs.
Compact and Portable
Small size and lightweight design make it easy to carry. The magnetic yoke plugs directly into a standard power outlet—no control unit required.
Durable and Safe
Well-sealed with strong insulation, offering added safety during wet inspections.
Ergonomic Design
