The coating thickness gauge, also known as the overlay thickness gauge, has the following principles and applications:

1、 Principle

Principle of magnetic thickness measurement: When the measuring head comes into contact with the coating, the measuring head and the magnetic metal substrate form a closed magnetic circuit. Due to the presence of the non-magnetic coating, the magnetic resistance of the magnetic circuit changes, and the thickness of the coating can be calculated by measuring its change.

Principle of eddy current thickness measurement: A high-frequency alternating current is used to generate an electromagnetic field in the coil. When the measuring head comes into contact with the covering layer, eddy currents are generated on the metal substrate, which provide feedback to the coil in the measuring head. The thickness of the covering layer can be derived by measuring the magnitude of the feedback effect.

2、 Applicable industries

1. Electroplating and spraying: This industry uses usinstrumentZ, which accounts for a significant proportion of our annual sales, is our main user group and requires a lot of effort to continuously explore.

2. Pipeline anti-corrosion: There are many users mainly in the petrochemical industry, and the anti-corrosion coating is generally thick. There are many users who use TT260 with F10 probe.

3. Aluminum profiles: Since the beginning of this year, the industry has shown good momentum due to the implementation of mandatory standards by the country and the renewal of licenses for profile enterprises. The main focus is on measuring the oxide film on profiles. It is understood that for every one micron less coating by production enterprises, one ton of profile "saves" 150 yuan, which is very considerable. Therefore, the country requires the provision of relevant testing equipment, including coating thickness gauges. This also brings us a very good opportunity. This opportunity has also attracted the attention of competitors, who have significantly lowered prices and quickly launched attacks in this industry through various means such as stocking. In response to this, Mr. Tang and Mr. Shi have repeatedly instructed to closely monitor and adopt corresponding strategies for the manual market, with the aim of giving up profits rather than the market. I hope our colleagues in the branch can also make good use of this opportunity, fully leverage our regional advantages, and make more of our products enter the industry, laying a 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: For our products, this type of enterprise can also be classified as a separate industry. Coating thickness gauges do have great applications in this industry, including manufacturers such as iron towers, and there is also a lot of recent purchasing information.
