Talking about the particularity of the measurement of the cladding Thickness Gauge and the choice of the substrate when calibrating

As a newly developed instrument and equipment, the cladding Thickness Gauge has the advantages of faster measurement speed, higher precision and good stability than the coating Thickness Gauge. The functions, data, operation and display are all in Chinese. Coating Thickness Gauges are widely used in chemical industry, metal processing industry, manufacturing industry, commodity inspection and other testing fields. This paper discusses and analyzes the particularity of cladding Thickness Gauge measurement and the selection of matrix during calibration. The cladding Thickness Gauge is an instrument required by the material protection profession. Nowadays, the requirements for the measurement and control of the thickness of the covering layer formed by the surface protection and decoration of industrial products are constantly increasing. Then speed up. The measurement of coating thickness is a very important link in the quality control and inspection of surface engineering of industrial products. In this paper, the problem of large measurement errors encountered in the measurement of coating Thickness Gauges in practical applications analyzes the particularity of coating Thickness Gauges based on the principle of magnetic induction measurement and eddy current measurement, and discusses many factors that affect the measurement results . Emphasize the importance of matrix selection.
