Natural gas refers to combustible gases, with common types including artificial gas. A gas leak detector is a device that detects gas concentrations, with its core component being a gas-sensitive sensor. Installed in areas prone to gas leaks, it triggers an alarm when the gas concentration in the air exceeds a set threshold, emitting both sound and light alarm signals. If connected to an alarm master unit and a receiving center, it can initiate network alarms. It can also automatically activate exhaust fans, close gas pipeline valves, etc., to ensure the safety of life and property. In civil safety and prevention projects, it is commonly used for residential gas leak alarms and is also widely applied in various refineries, oil depots, chemical plants, liquefied gas stations, and other places where flammable gas leaks may occur. Faced with the various accident threats caused by gas leaks, is there really no comprehensive solution? According to some experts, detecting gas leaks is one of the crucial means to combat the invisible killer of gas. Gas experts point out that gas leakage or exhaust emissions are the root cause of gas poisoning incidents, and timely warnings can be obtained by detecting gas leaks. Relevant departments have also concluded, after long-term testing, that the effectiveness of preventing gas poisoning and explosion accidents is over 95%.
