Non-destructive testing instrument types: ultrasonic flaw detector, magnetic particle flaw detector, X-ray flaw detector, gamma-ray flaw detector, eddy current flaw detector, acoustic emission flaw detector, magnetic memory flaw detector, etc. And penetrant.
Precautions:
X-ray thickness gauge is a non-contact dynamic measuring instrument, which uses the characteristics that the change of X-ray intensity is related to the thickness of the material when X-ray penetrates the measured material to determine the thickness of the material. It takes PLC and industrial computer as the core, collects calculation data and outputs the target deviation value to the rolling mill thickness control system, which achieves the required rolling thickness.
Eddy current thickness gauge is a small instrument, which can conveniently and non-destructively measure the thickness of paint, plastic, rubber and other coatings on non-ferrous metal substrates or anodic oxide films on aluminum substrates. The instrument is widely used in machinery, automobile, shipbuilding, petroleum, chemical industry, electroplating, plastic spraying, enamel, plastic and other industries.
