Working Technique of Coating Thickness Gauge


Measuring the coating thickness is an essential practice that contributes todetermining the quality of the product, its process control and pricing. There are many different instruments that can be used in measuring the thickness of the coating. In order to understand the instrument which is being used in measuring the thickness of a coating, it is important to know the working technique of a coating thickness gauge. There are several factors that determine the method that is best while using the coating thickness gauge and these factors include the type of coating, the substrate material, the thickness of the coating, the shape and the size of the coating etc. These factors help in the process of using the coating thickness gauge. For different materials and thickness, different techniques are used. Here we have mentioned the popular techniques. So scroll down and check out:

§  Magnetic Film Thickness Gauges: It is used in the non-destructive method of finding the thickness of the dry film of a non-magnetic coating over the ferrous substrates. Most of the coatings which are on the surface of steel and iron are measured using this technique.

§  Magnetic Pull-off Thickness Gauges: In this technique, a permanent magnet is used along with a calibrated spring. It also involves a graduated scale. In this technique, the attraction between the magnet and magnetic steel helps in pulling both of them together. With the help of measuring the pull-off force, the thickness is counted.

§  Electromagnetic induction thickness gauges: These thickness gauges come in various shapes and sizes. It commonly uses the constant pressure probe in order to give consistent readings which has no influence from the various operators. You can check the readings on the LCD and with the help of these gauges you can store the readings and get the instant analysis of the data generated.
We hope the above-mentioned details are helpful in offering the desired information regarding the technique used in operating the Coating Thickness Gauge. This valuable information will help you in using the various types of Coating Thickness Gauge. If you have any other questions regarding the using technique of Coating Thickness Gauge, feel free to ask us on the comment section.

Advantages of Universal Testing Machine

The main advantage of investing in a universal testing machine is that the device can be used to test the strength, durability, and suitability for most any material. A universal testing machine has the capability to pull, compress, bend, or stretch material to its breaking point. It is primarily used by laboratories that manufacture and or mould different types of plastics. A universal testing device features one or two vertical columns mounted on a base. A second horizontal plate contains attachments that are used to hold the sample and slides up and down during stress testing samples. Dual vertical column machines are preferred by most laboratories as they can handle larger samples in terms of size and weight. Determining tensile strength is the most common test performed in a universal testing machine. This is done by holding one end of a sample in place while the other is pulled away until two sides are torn apart. The same process is used for testing flexural str...

Uses for Universal Testing Machine

Universal testing machine or UTM is aptly named as it can perform various types of tensile and compression tests on different materials. There are also many different terms used to refer to a UTM that you will commonly hear in the industry, among the most popular of which are a tensile tester, bend tester, and compression tester. Some types of UTMs are stripped of some capabilities and/or are marketed to specific sectors, like texture analyzers for food, peel tester for adhesives, labels, and tapes, and top load compression tester for pipes and packaging. True UTMs can perform all of these and more. They are great multi-purpose instruments for any QC or R&D laboratory. The following are only a few common uses for UTMs: Tensile testing – One of the most common applications for UTM, a tensile test measure how strong a material is, how long it can stretch, and how stiff it is as the material is pulled apart until breaking point. Compression testing – Compr...

Importance of Ultrasonic Pulse Velocity Test in The Construction Industry

Image
In the construction industry, it is important to ensure that structures are built properly using the highest-quality materials and construction methods. Hence, certain tests must be conducted to ensure the quality of certain materials. The ultrasonic pulse velocity test is one of the most essential tests designed to determine the quality of natural rock and concrete. This testing method is preferred because it is non-destructive and it is conducted on site, saving builders a lot of time and money. In an ultrasonic pulse velocity test, the quality and strength of rock or concrete is determined by measuring the velocity of the ultrasonic pulse, which passes through the natural rock formation or concrete structure. The test is conducted using specialised equipment that generates a pulse of ultrasonic wave and measuring the time it takes for that pulse to go through the concrete. A high velocity indicates that the material is continuous and high-quality, and a slower velocity may ...
