Overview
The MMP-200 Portable Yoke Flaw detector is a professional precision instrument under the MITECH brand. It is based on the improved design of traditional Magnetic Particle Testing Equipment, and has the characteristics of small size, light weight, safety and reliability. The instrument can be directly connected to the AC power supply, and can also be used with AC magnetization power supply and DC magnetization power supply. It takes into account both AC and DC flaw detection applications to solve the drawbacks of traditional Magnetic Particle Testing Equipment relying on 220V power supply. Especially suitable for hull weld inspection, high-altitude structure weld inspection and Pressure Vessel internal operation, is the power, metallurgy, petrochemical, machinery and other industries of all kinds of steel structure, boiler, Pressure Vessel, pressure pipeline and various types of welding structure of ferromagnetic material surface magnetic particle detection ideal tool.
Features
1. According to the magnetic interaction between the leakage magnetic field and the magnetic particles, the shape, location, size and severity of the defect can be intuitively displayed, and the nature of the defect can be determined.
2. Three power supply modes can be freely selected: single AC power supply, AC magnetization power supply, and DC magnetization power supply.
3. The yoke spacing is adjustable to meet the testing needs of different customers, with a wide range of applications.
4. Integrated design, compact structure, reasonable layout, small size, light weight, easy to carry.
5. Equipped with a special fanny pack, it can carry magnetization power supply, magnetic suspension, and contrast agent, making it portable and efficient.
Principle
The MMP-200 Portable Yoke Flaw detector works according to the principle of magnetic interaction between leakage magnetic fields and magnetic particles. When a ferromagnetic material is magnetized, if there is a defect on or near the surface, a leakage magnetic field will form at the defect, and the applied magnetic particles will be adsorbed to visually display the shape, location, size and severity of the defect, helping to determine the nature of the defect.
Applications
Electric power, metallurgy, petrochemical, machinery and other industries of various types of steel structures, boilers, Pressure Vessels, pressure pipelines and various types of welded structures of ferromagnetic material surface magnetic particle detection, hull weld inspection, high-altitude structure weld inspection, Pressure Vessel internal work
