Edry current control

About the main provisions

The advantages of this method are as follows:

• there is no physical contact with the product;
• no contact medium, such as water, is required;
• high performance.

The objectives of the study are as follows:

• identification of inhomogeneities in the product, which may adversely affect its fitness for purpose;
• measurement of the thickness of coatings or layers;
• measurement of other geometric characteristics;
• measurement of metallurgical or mechanical properties of the product;
• measurement of conductivity and/or permeability of the product;
• sorting products by any of the above properties.

Examples of controlled items are conductive materials such as:

• pipes, profiles, beams or bars;
• parts in the automotive and engineering industries;
• forged or cast products;
• multilayer components in aircraft construction.

Examples of using this method are as follows:

• flow control in the rolling mill, painting or exhaust line;
• checking the pipelines of heat exchangers during their operation;
• checking the properties of mass-produced goods and semi-finished products;
• checking aircraft during maintenance;
• checking the surfaces of cylindrical holes formed in products.
