Overview
MMP-200D Portable Yoke Flaw detector is a professional precision instrument based on the modified design of traditional Magnetic Particle Testing Equipment. It is small in size, light in weight, safe and reliable, and can be directly connected to AC power supply. It can also be equipped with AC or DC magnetization power supply. It takes into account both AC and DC flaw detection applications and solves the dependence on fixed 220V power supply. It is especially suitable for operation scenarios such as hull welds, high-altitude structural welds and the interior of Pressure Vessel. It is an ideal tool for magnetic particle detection on the surface of 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 visually displayed, and the nature of the defect can be determined.
2. Provide three power supply modes to choose from: single AC power supply, AC magnetization power supply, and DC magnetization power supply.
3. The yoke spacing is adjustable to meet different inspection requirements and has 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 to achieve portable and efficient operation.
6. The instrument meets the requirements of JB/T7411-2012 "Electromagnetic Yoke Flaw detector Technical Conditions" standard.
Principle
The MMP-200D Portable Yoke Flaw Detector is an improved design based on the traditional Magnetic Particle Testing Equipment. It generates a magnetic field in a ferromagnetic material through a yoke. When there is a defect on or near the surface of the material, a magnetic leakage field is formed. Based on the magnetic interaction between the magnetic leakage field and the magnetic particles, the magnetic particles will gather at the defect, thereby visually showing the shape, location, size and severity of the defect, which in turn helps 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
