What Sets Coating Thickness Gauge Apart From Other Thickness Gauges
Coating thickness gauges are mainly used in the surface treatment industry to measure the coating thickness on metal or plastic surfaces. There are many names for coating thickness gauges, commonly used coating thickness gauges, cladding thickness gauges, anti-corrosion layer thickness gauges, portable thickness gauges, dry film thickness gauges, magnetic thickness gauges, eddy current thickness gauges, Film thickness gauge, coating thickness gauge, metal film thickness gauge, paint coating thickness gauge, paint thickness gauge, powder coating thickness gauge, film thickness tester, film thickness gauge, electroplating thickness gauge, film thickness gauge Thickness gauge, paint film thickness gauge, etc., are actually the same instrument.
The electrolytic thickness gauge is specially used to measure the relatively thin coating, and the substrate or coating is relatively special, such as the measurement of nickel plating on iron with only a few microns of coating. But the surface coating must be destroyed.
Ultrasonic coating thickness gauge is a thickness gauge for measuring the coating thickness of wood, plastic, glass and other non-metallic surfaces. The price is quite expensive. Therefore, some measurements in the spraying process can be replaced by ordinary coating thickness gauges. The specific measurement method is as follows: put the ordinary coating thickness gauge diaphragm (calibration sheet) together with the product that has not undergone surface treatment, and then After spraying, use an instrument to measure the thickness of the film, so as to know the thickness of the product coating.
The ultrasonic thickness gauge measures the thickness according to the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the interface of the material, the pulse is reflected back to the probe to determine the time of ultrasonic propagation in the material. The thickness of the material. It is mainly used to measure the thickness of the entire steel plate, iron plate, glass plate, etc., and it has nothing to do with the coating. Therefore, when purchasing and using, it is necessary to distinguish whether it is an ultrasonic coating thickness gauge or an ultrasonic thickness gauge.
The X-ray thickness gauge uses the characteristics that the X-ray intensity changes and the thickness of the material when the X-ray penetrates the measured material, so as to measure the thickness of the material. It is a non-contact dynamic measuring instrument. It takes PLC and industrial computer as the core, collects and calculates data and outputs the target deviation value to the thickness control system of the rolling mill, and has reached the required rolling thickness.
There are two types of non-destructive coating thickness gauges: magnetic and eddy current, and there is also a magnetic eddy current two-in-one dual-purpose type. It is often used to measure the thickness of the coating on the surface of a metal substrate, so it is also called a coating thickness gauge. The magnetic thickness gauge is designed to measure the thickness of the coating on magnetic metals such as steel (except for magnetic metals such as steel and nickel). The coating on non-magnetic copper, aluminum, tin, etc. cannot be measured. The eddy current thickness gauge is designed to measure the thickness of the insulating layer on non-magnetic metals, such as copper and aluminum (the coating must be a non-conductive material).
