Magnetic Particle Crack Detector About
The Magnetic Particle Crack Detector is a highly efficient and portable device designed for detecting cracks and defects in ferromagnetic materials. It is widely used in industries such as construction, power plants, shipbuilding, oil & gas, and manufacturing for inspecting welds, pipelines, pressure vessels, and structural components.
The equipment consists of a magnetic yoke that generates a strong magnetic field when placed on the test surface. When magnetic particles (dry powder or wet suspension) are applied, they accumulate at defect locations, making cracks clearly visible to the inspector.
The instrument is compact, lightweight, and easy to operate, making it suitable for both field and laboratory testing. Advanced models support both AC and DC magnetization, allowing detection of surface as well as slightly subsurface defects.
