In industrial applications, various tools are used in various applications. One of such tools is a Coating Thickness Gauge. This device is useful for measuring the thickness of coatings applied to different substrates.
Coating thickness gauge manufacturers bring good-quality instruments that work by measuring the thickness of a coating on a substrate. It employs different principles that depend on the type of gauge and the materials involved.
If you get top-class gauges made by reputed manufacturers like MEXTECH, then you get accurate results and correctness of the application.
Primary methods used by coating thickness gauges
Magnetic induction method
This method is useful in non-magnetic coatings on ferrous (magnetic) substrates. For example, measurement of paint on a steel surface.
In this method, the gauge generates a magnetic field. When you place it on a coated ferrous substrate, the magnetic flux is affected by the thickness of the non-magnetic coating. This is measured by the gauge and the coating thickness is obtained.
Eddy current method
This method is useful in non-conductive coatings on non-ferrous (non-magnetic) substrate. For example, anodizing aluminum.
In this method, the gauge induces eddy currents in the conductive substrate. Due to the presence and thickness of the non-conductive coating, the flow of current gets affected. The gauge measures the thickness of the coating. It can measure the thickness of an anodized layer on aluminum.
Ultrasonic method
This method is useful in measuring thickness of coatings on various substrates, e.g., non-metallic coating on plastic or wood.
In this method, the gauge emits ultrasonic pulses. These pulses travel through the coating and reflect back from the substrate. The time taken for the echo is proportional to the coating thickness. It can measure the thickness of a protective coating on a wooden surface.
The best coating thickness gauge company brings top-quality, precise tools to carry out measurements accurately.
Applications for Coating Thickness Gauge
Automotive Industry
In quality control process, this is useful for ensuring that the paint and other coatings on vehicles meet the standards of specified thickness. Similarly, it is useful in corrosion protection. The gauge checks that the anti-corrosion coatings on automotive parts are adequate.
Manufacturing and production
In manufacturing and production processes, the gauge is used for product finishing. You can ensure consistency and uniformity of coatings on products like appliances, machinery, and consumer goods. It checks that the coating does not have any flaking or peeling, and it is thick enough to adhere well.
Aerospace
In the aerospace industry, the gauge ensures safety and performance standards by checking the coatings on parts. These standards are insulation layer checking and anti-corrosion state. In aerospace, it is also used for weight management of coating thickness.
Marine industry
In this industry, thickness gauge is used for measuring the thickness of anti-fouling and anti-corrosion coatings on the hulls of ships. This is helpful in giving protection against seawater corrosion and marine growth. The gauge ensures the integrity of offshore platforms or underwater structures.
Electronics and Electrical Industry
Thickness gauge ensures proper coating thickness so that electronic components get insulation and protection. It can also prevent oxidation and enhance conductivity of component coating.
