The gas controller is the core control unit of the gas detection and alarm system. It receives signals from various types of gas detectors and processes and analyzes the detection data. The outer shell is usually made of sturdy and durable metal materials with good shielding performance to prevent external electromagnetic interference from affecting data accuracy. The internal circuit design is complex and precise, with powerful data processing and logical judgment capabilities. Its advantage lies in its ability to manage multiple gas detection channels simultaneously, enabling centralized monitoring of multiple gases; it can automatically trigger the alarm device according to preset thresholds to issue alarms in a timely manner; and it has data storage and query functions for users to view historical detection data. It is widely used in industrial sites such as chemicals, petroleum, and metallurgy to ensure gas safety during the production process.
