Minimum re Russian Federation | | | | | Reference Weight made of pig iron with high-quality casting surface. The weights are used for scales calibration and as the part of loading-and-testing machines. Russian Federation | | | | | “VANGA” is widely used for revealing areas of heterogeneity of metals. Samples covered with varnish, paint or other dielectric materials in a layer not thicker than 2 mm can be easily detected. It is comfortable in use, mobile and reliable.
Varying sound signal tone depicts the area of heterogeneity revealed by highly sensitive device. “VANGA” has autonomic power supply, automatic tuning and normalization of the load between sensor element and surface.
Field of application: non-destructive defectoscopy.
• Detection of non-uniformity in structure of metals and other conductive materials.
• Finding micro cracks in metal structure.
• Investigation of covering dielectric duration, i.e. paint, filler, polymer films over metal.
• Prognosis of mechanical damage in important parts of machines and installations.
• Determination of welding junctions, boundaries.
• Investigations of car identification numbers authenticity.
