The gauges are used for many different purposes today, including the automotive industry. They can measure paint thickness, which can provide accurate and fast detection of refinished surfaces. They can be helpful for those who are buying vehicles at auctions, as the vehicles may have been refinished for one reason or another. This tool can provide appraisers and insurance inspectors with an ability to detect whether it has been refinished, and to have a better idea of the quality of the paint on the vehicle.
The tools are often used in garages, body shops, and at auto dealers for the same reasons.
The magnetic induction principle is used with the gauge when measuring coatings that are on ferro magnetic substrates. This would include things such as iron or steel. The eddy current principle works to measure coatings on nonmagnetic surfaces. This would include things such as aluminum, bronze, copper, and alloys. In addition, the coatings themselves need to be electrically insulating. This would include ceramics, anodized coatings, pain, plastics, and enamel.
The field of metrology is the science of measurement, and with the range of technology available today, it is possible to measure nearly anything. Those who need to measure the thickness of a coating will find that a coating thickness gauge is an excellent choice for those who need a nondestructive method of getting a measurement. Another one of the benefits of these types of devices is the accuracy. The gauges can typically use different methods of calculating thickness using magnetic induction and eddy current.
Coating thickness gauges are manufactured by many companies today. Some of the popular options on the market include Phase II and Phynix.
