Pros and Cons of Coating Thickness Gauge


Before knowing the advantages and disadvantages of a coating thickness gauge, understand what the device does. It is a device that measures the thickness of a dry film. The most critical form of measurement when it comes to coatings industries is the measurement of dry film coating. The measurement readings determine the life expectancy of the layer.

Advantages
1. It has two forms: The coating thickness gauge machines come in two forms, a mechanical one and a digital one. Mechanical ones are perfect for working in high-risk areas like underwater or flammable zones. Digital ones have a design which enables it to provide accurate measurements on any substrate, whether metallic or non-metallic.

2. Accuracy: With the advancements in science and technology, designers manufacture coating thickness gauges that are very accurate. However, it depends on the level of precision you need in your work. If you are buying a device from a renowned company, then you will get the most precise readings every time.

Disadvantages

1. The eddy current principle: Even after resorting to single-coil probe for the eddy current law, a flow of alternating current circulates in the substrate. As a result, magnetic fields start to form which influences the coating thickness probe. It also brings about changes in the electrical impedance of the coil.

2. Expensive: Every commercial person will want a coating thickness gauge which gives accurate readings. Several manufacturing companies are producing the machine, but only the expensive ones are accurate. When it suits your business, you are ready to make expenses, but if the product is too costly, then it can hurt the industry.

Choose wisely

Always remember to calibrate the coating thickness gauge before you test. The calibration process will ensure that a device does not read a different coating value on two different metal surfaces having the same level of coating. Keep the pros and cons of the coating thickness gauge in mind while buying so that you get the best deal for your investment.

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

Precautions to Be Taken While Using a Piezometer

The piezometer is a measuring device that determines pore pressures underground and liquid pressure. By determining pore pressure, you can understand the behaviour of the ground before, during, and after a construction project. Certain precautions must be taken when using a piezometer to ensure proper usage and the accuracy of results. Here are some of them: Have the right equipment – Invest in a state-of-the-art piezometer that uses a proven method of converting fluid pressures on the sensitive diaphragm into frequency signals which are ideal in the demanding environment common with civil engineering applications. Modern piezometers are capable of long distance signal transmission without degradation. They can tolerate wet wiring conditions and resist external electrical noise, too. Some manufacturers make piezometers specific for different applications, for instance, you should be able to find one with a heavy-duty body that can be b
