Overview
MMP-200DL Portable Yoke Flaw detector is an improved magnetic particle flaw detection equipment under the MITECH brand. The instrument is small in size, light in weight, safe and reliable, can be directly connected to AC power supply, or optional AC or DC magnetization power supply, taking into account both AC and DC flaw detection applications, solving the drawbacks of traditional equipment relying on 220V power supply. It is especially suitable for working environments such as hull welds, high-altitude structural welds and Pressure Vessel interiors. It is a professional precision instrument for magnetic particle detection on the surface of various ferromagnetic materials in electric power, metallurgy, petrochemical, machinery and other industries.
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.
6. The instrument meets the requirements of JB/T7411-2012 "Electromagnetic Yoke Flaw detector Technical Conditions" standard.
Principle
The MMP-200DL Portable Yoke Flaw Detector is an improved design based on the traditional Magnetic Particle Testing Equipment. It magnetizes the ferromagnetic workpiece through the yoke. When there is a defect on or near the surface of the workpiece, a magnetic leakage field will be formed, and the applied magnetic particles will be adsorbed, so as to visually display the morphology, location and size of the defect.
Applications
Surface flaw detection of ferromagnetic materials for various steel structures, boilers, Pressure Vessels, pressure pipelines and various types of welded structures in electric power, metallurgy, petrochemical, machinery and other industries
Standards
