Product Introduction
I. Industrial Explosion-proof Alarm, Real-time Gas Leak Monitoring Product Overview
The combustible gas alarm consists of a detector and an alarm controller, and is an industrial explosion-proof safety monitoring device. It detects the concentration of combustible gases such as natural gas, liquefied gas, methane, and propane in real time. When the gas concentration reaches the preset alarm threshold, it automatically triggers audible and visual alarms and can link with solenoid valves, exhaust fans, and other equipment to quickly eliminate explosion hazards. Widely used in chemical plants, gas stations, boiler rooms, restaurant kitchens, coating workshops, and tank farms, meeting safety production acceptance requirements.
II. Industrial Explosion-proof Alarm, Real-time Gas Leak Monitoring Product Introduction
The complete system includes现场探测器withAlarm hostTwo major units. The detector is installed in locations where gas tends to accumulate, collecting gas concentration signals in real time and transmitting them to the alarm host via cable; the host centrally displays the concentration at each monitoring point and saves alarm records. The equipment uses an explosion-proof enclosure, adaptable to harsh working conditions such as dust and humidity. The fixed model provides 24-hour uninterrupted online monitoring; the portable model is used for on-site inspection and leak detection. The product has explosion-proof certification, supports engineering installation, prevents fire and explosion accidents caused by combustible gas leaks, and ensures the safety of plant equipment and personnel.
