The gas leakage alarm consists of a detector and an alarm control host. Widely used in petroleum, natural gas, chemical industry, oil depot and other petrochemical industries with toxic gases. Used to detect the leakage of indoor and outdoor dangerous places, it is an important instrument to ensure production and personal safety.

When there is toxic gas in the tested place, the detector converts the gas signal into a voltage signal or a current signal and sends it to the alarm, which displays the percentage concentration value of the lower explosion limit of combustible gas. When the concentration of combustible gas exceeds the alarm set value, there will be an audible and visual alarm signal, and the personnel on duty will take safety measures in time to avoid explosion accidents.

The gas leak detector is installed where gas leakage may occur. When the gas concentration in the air exceeds the set value, the detector will be triggered to give an alarm and send out an audible and visual alarm signal. If the alarm host is connected to the alarm center, it can alarm on the internet, and at the same time automatically start the exhaust equipment and close the gas pipeline valve to ensure the safety of life and property.

In civil safety prevention engineering, it is mostly used for household gas leakage alarm, and also widely used in various refineries, oil depots, chemical plants, liquefied gas stations and other places prone to flammable gas leakage.

Using gas leak alarm is one of the important means to deal with gas stealth killer. Gas experts point out that a large amount of carbon monoxide produced by gas leakage or waste gas discharge is the root of gas poisoning reaction, and if a useful gas leakage alarm is used, it can be warned in time.
