The ethane leakage alarm system consists of a controller and gas detectors, featuring easy installation and networking for centralized control of multiple monitoring points. When the concentration of leaked ethane gas in the environment reaches or exceeds the preset alarm value, the ethane leakage alarm will issue an alert to remind the user to take safety measures, thereby preventing and reducing the occurrence of accidents and avoiding their consequences and hazards. It plays a protective role for your safety and property. Three-level alarm: Pre-warning, low limit/high limit alarms can be set. 4 programmable emergency buttons ("Linkage 1", "Linkage 2", "Linkage 3", "Linkage 4"). 4 groups of programmable relay contact outputs, outputting control signals respectively to link exhaust fans, solenoid valves, and other linked equipment. Other detectors (4-20mA standard signal or passive switch signal) can be integrated into this system via input modules, facilitating system integration.
