Permanent Magnetic Yoke DELTA PM-25
Permanent Magnetic Yoke DELTA PM-25 for Magnetic Particle Testing
The Permanent Magnetic Yoke DELTA PM-25 is a high-performance tool designed for non-destructive testing (NDT) using the magnetic particle method. It effectively detects surface and sub-surface defects in ferromagnetic materials, ensuring compliance with industry standards, including ASTM E1444, ASTM E709, ASTM 3024, and ASME Section V, Article 7.
Ideal for inspecting welded joints and metal surfaces, this magnetic yoke generates a powerful applied magnetic field to reveal flaws in critical product areas.
Key Features of the Permanent Magnetic Yoke DELTA PM-25
- Advanced Magnetic Pole Design: Provides precise magnetization of the product sections. The poles can be positioned in the same plane or at perpendicular angles, creating a directional magnetizing field.
- Versatile Application: Perfect for use in workshops, laboratories, and field conditions, including high-altitude facilities and environments where power supply is unavailable or restricted by safety regulations.
- Wide Operating Range: Functions in extreme temperatures from -30°C to +50°C with humidity levels up to 95%.
