The principle and applicable industries of coating thickness gauge
Coating thickness gauge is also called coating thickness gauge. The principle and application are as follows:
principle
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.
Applicable industries
1. Electroplating and spraying: This industry uses the most of our instruments and accounts for a large proportion of annual sales. It is our main user group and requires a lot of energy to continuously explore.
2. Pipeline anti-corrosion: There are many users in the petrochemical industry. Generally, the anti-corrosion layer is relatively thick. There are many users of TT260 equipped with F10 probe.
3. Aluminum profiles: Affected by the implementation of mandatory standards by the state and the renewal of licenses by profile companies this year, the industry has gained momentum. The main purpose is to measure the oxide film on profiles. It is understood that for every one micron less plated by a manufacturer, one ton of profiles The "saving" of 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 their prices as much as possible and quickly launched an offensive in this industry through various methods such as product distribution. In response to this, Mr. Tang and Mr. Shi have repeatedly instructed to pay close attention to their competitors. The trend of the times is to adopt corresponding strategies, with the purpose of giving profits to the market. We hope that our colleagues in the branch can make good use of this opportunity and give full play to their regional advantages so that more of our products can enter this industry and lay the foundation for future sales in this industry. In addition, we can also expand the impact of our products in the entire market.
4. Steel structure: Enterprises with our products can also be classified as an industry separately. Coating thickness gauges are indeed widely used in this industry, and manufacturers including iron towers and other manufacturers have recently purchased more information.
