Detailed Overview

The PM2004 Permanent Magnet Yoke is a specific model designed for non-powered Magnetic Particle Inspection (MPI). It utilizes powerful rare earth magnets to generate a reliable, static magnetic field to attract magnetic particles to flaws. The PM2004 distinguishes itself from similar models (like the PM2000) by featuring fixed legs joined by an interlinking cable, offering a unique geometry that is highly advantageous for inspecting certain difficult-to-access components. This design provides a powerless and highly lightweight solution for quick field MPI checks.

A specialized permanent magnet yoke with high lifting power for demanding field MPI.

• This model offers a powerful magnetic field, exceeding the minimum 18 kg lifting power required by international standards, ensuring sufficient flux density for reliable crack detection.
• It is completely independent of any power source
• The PM2004 features a design with fixed legs and an interlinking cable, allowing for a wide variety of pole spacings and making it particularly easy to work on awkward angles or irregular shapes.
• The product is an ultra-lightweight permanent magnet yoke with a comfortable grip, high lifting power specification, and a robust storage box.

Primary Uses & Functions

The PM2004 permanent magnet yoke is used to induce a residual magnetic field (DC static field) in a ferromagnetic component for Magnetic Particle Inspection (MPI), enabling the detection of surface and sub-surface discontinuities without the need for an electrical source.

Real-World Applications

• Used in Magnetic Particle Inspection (MPI) to create a localized DC magnetic field in ferromagnetic materials.
• Requires no external power source, making it highly portable and the preferred choice for inspection in elevated areas or confined spaces.
• Specifically suited for crack detection in welds, pressure vessels, and structures where an arc or spark from an electrical yoke is a concern.
• The cable-linked fixed legs are particularly useful for wrapping around a pipe or conforming to a difficult profile.

Technical Specifications

Compatibility

• Specifically a variant of permanent magnet yoke, offering an alternative to the PM2000 (which has articulating legs) by using fixed legs joined by an interlinking cable.
• Used for Magnetic Particle Inspection (MPI) in areas where mobility, safety, and lack of power are critical factors.
• Suitable for use with dry or wet (fluorescent or visible) magnetic particles.
