How coating thickness gauges differ from other thickness gauges
In the surface treatment business, coating thickness gauges are primarily used to gauge the thickness of coatings applied to metal or plastic surfaces. Coating thickness gauges go by a variety of names, including coating thickness gauges, anti-corrosion layer thickness gauges, portable thickness gauges, dry film thickness gauges, magnetic thickness gauges, eddy current thickness gauges, and coating thickness gauges. Film thickness tester, film thickness gauge, coating thickness gauge, metal film thickness gauge, paint thickness gauge, paint thickness gauge, powder coating thickness gauge, and thickness gauge for electroplating The thickness gauge, paint film thickness gauge, and other terms for it all refer to the same tool.
When measuring relatively thin coatings, such as nickel plating on iron with only a few microns of coating, an electrolytic thickness gauge is specifically utilized, and the substrate or coating is relatively special. But it is necessary to remove the surface covering.
Ultrasonic coating thickness gauges are used to measure the coating thickness on non-metallic surfaces such as glass, plastic, wood, and plastic. The cost is fairly high. Therefore, standard coating thickness gauges can take the role of various spraying process measurements. This is the precise measurement technique: assemble the product without surface treatment with the common coating thickness gauge diaphragm (calibration sheet), and then To determine the thickness of the product coating after spraying, use an equipment to measure the thickness of the film.
Using the ultrasonic pulse reflection theory, the ultrasonic thickness gauge calculates the thickness. The ultrasonic pulse that the probe emits is reflected back to the probe when it reaches the material's interface, allowing the probe to calculate the measurement time by timing how long the ultrasonic wave takes to travel through the material. the material's thickness. It has nothing to do with the coating and is mostly used to measure the thickness of the complete steel plate, iron plate, glass plate, etc. It is therefore important to tell the difference between an ultrasonic coating thickness gauge and an ultrasonic thickness gauge when buying and using one.
The X-ray thickness gauge measures the thickness of the material by utilizing the characteristics that the X-ray intensity varies and the thickness of the material when the X-ray penetrates the measured material. It is a dynamic measurement device without contact. It uses a PLC and an industrial computer as its central processing unit, gathers and computes data, outputs the target deviation value to the rolling mill's thickness control system, and achieves the necessary rolling thickness.
Non-destructive coating thickness gauges come in two varieties: magnetic and eddy current, as well as a magnetic eddy current two-in-one dual-purpose kind. It is also known as a coating thickness gauge since it is frequently used to gauge the thickness of the coating applied to the surface of a metal substrate. The purpose of the magnetic thickness gauge is to assess how thick the coating is on magnetic metals like steel (except for magnetic metals such as steel and nickel). Copper, aluminum, tin, and other non-magnetic metals cannot have their coatings measured. Measure the thickness of the insulating layer on non-magnetic metals like copper and aluminum using the eddy current thickness gauge (the coating must be a non-conductive material).
