Principle and Applicable Industry of Coating Thickness Gauge
Coating thickness gauge is also called cladding thickness gauge, the principle and application are as follows:
1. Principle
The principle of magnetic thickness measurement: when the probe is in contact with the coating, the probe and the magnetic metal substrate form a closed magnetic circuit. Due to the existence of the non-magnetic coating, the reluctance of the magnetic circuit changes. By measuring the change, the coating thickness can be calculated. thickness.
The principle of eddy current thickness measurement: use high-frequency alternating current to generate an electromagnetic field in the coil. When the probe is in contact with the covering layer, an eddy current is generated on the metal substrate and has a feedback effect on the coil in the probe. By measuring the size of the feedback effect The thickness of the covering layer can be exported.
2. Applicable industries
1. Electroplating and spraying: This industry uses our instruments the most, accounting for a considerable proportion of annual sales, and is our main user group, which requires great energy to continuously dig.
2. Pipeline anticorrosion: There are many users mainly in petrochemical industry, generally the anticorrosion layer is relatively thick, and there are many users who use TT260 with F10 probe.
3. Aluminum profiles: Affected by the country’s implementation of mandatory standards and the renewal of licenses by profile companies since the beginning of this year, the industry has shown a good momentum. It mainly measures the oxide film on the profiles. The "saving" of 150 yuan is very considerable, so the state mandates that relevant testing equipment including coating thickness gauges be equipped. This move also brought us a very good opportunity. This opportunity has also attracted the attention of competitors. They lowered the price to the greatest extent, and quickly launched an offensive in this industry through various methods such as distribution of goods. For this, Mr. Tang and Mr. Shi have repeatedly instructed to pay close attention to their competitors. Dongxiang Shishi adopts corresponding strategies, with the purpose of giving up profits and not letting the market. It is hoped that colleagues in the branch company can make good use of this opportunity and give full play to the regional advantages so that more of our products can enter this industry and lay a foundation for future sales in this industry. In addition, it can also expand the influence of our products in the whole market.
4. Steel structure: For our products, such enterprises can also be classified as an industry separately. Coating thickness gauges do have great applications in this industry, and manufacturers including iron towers have more recent purchase information.
