Coating thickness gauge application industry and classification
The application industries of coating thickness gauges include electroplating, spraying, pipeline anti-corrosion, aluminum profiles, steel structures, printed circuit boards, and screen printing, etc.
Electroplating and spraying: This industry uses a lot of our instruments and accounts for a large proportion of annual sales. It is our main user group and requires energy to continuously explore.
Pipeline anti-corrosion: There are many users in the petrochemical industry. Generally, the anti-corrosion layer is relatively thick. There are many users of the KY8001 KY8002 thickness gauge;
Application industries and classifications of coating thickness gauges
Aluminum profiles: Affected by the implementation of mandatory standards by the state and the renewal of licenses for profile companies this year, the industry has seen a good momentum. The main purpose is to measure the oxide film on the profiles. It is understood that for every one micron less plated by the manufacturer, one ton of profiles will "save" "150 yuan is very considerable, so the state mandates the installation of relevant testing equipment including coating thickness gauges. This move also brings us very good opportunities. This opportunity has also attracted the attention of competitors. They have lowered prices to the greatest extent and quickly launched an offensive in this industry through various methods such as product distribution.
Steel structure: For our products, this type of enterprise can also be classified as an industry separately. Coating thickness gauges do have a lot of applications in this industry, and manufacturers including iron towers and other manufacturers have a lot of recent purchasing information;
Printed circuit boards, screen printing, etc.: This type of enterprise is relatively special industry, and the purchase volume currently only comes from a few scattered manufacturers.
Detection principle of coating thickness gauge
Principle of magnetic thickness measurement: When the probe is in contact with the coating, the probe and the magnetic metal matrix form a closed magnetic circuit. Due to the existence of the non-magnetic coating layer, the magnetic resistance of the magnetic circuit changes. By measuring the change, the resistance of the coating layer can be calculated. thickness.
Principle of eddy current thickness measurement: high-frequency alternating current is used to generate an electromagnetic field in the coil. When the probe is in contact with the covering layer, eddy current is generated on the metal substrate and produces a feedback effect on the coil in the probe. The size of the feedback effect is measured. The thickness of the overlay can be exported.
According to the detection principle of coating thickness gauge: it can be divided into magnetic coating thickness gauge, that is, the substrate to be measured is magnetic, such as steel, iron, etc., and there is also a non-magnetic coating thickness gauge as the name implies. , also called eddy current thickness gauge, if the substrate is aluminum. There is also a dual-function coating thickness gauge, which means that whether the substrate is iron or aluminum, it can be automatically identified. Customers can choose according to their own measurement needs.
