This PLC automatic gas high pressure testing equipment is a professional leak testing system that integrates high precision, full automation and intelligence. It adopts advanced PLC (Programmable Logic Controller) and touch screen operation interface to achieve efficient, stable and automatic control of the entire airtightness testing process.
Product Features
1. High-pressure testing capability: Equipped with an efficient gas booster, the maximum test pressure can reach 80 MPa, meeting various requirements for high-pressure sealing tests.
2. Automatic pressure control: During the test, the high pressure test equipment automatically increases pressure, maintains pressure, holds pressure and releases pressure without manual intervention. The system automatically maintains the set pressure.
3. Intelligent result determination: PLC automatically collects pressure data and precisely determines the leakage situation through various algorithms such as pressure drop method and differential pressure method, and outputs the test results in real time.
4. User-friendly operation interface: Equipped with a touch screen, parameter setting is intuitive and simple. It supports test data storage, query and export.
5. High precision and repeatability: The automated process significantly reduces human error, ensuring the consistency and reliability of the test results.
