With the development of economy, natural gas, as a high-quality, efficient and clean fossil fuel, has been widely used in national life and all walks of life. Some experts believe that the 21st century will be the era of natural gas. In recent years, my country has vigorously laid gas pipelines, and the penetration rate of national gas use has been rising. At the same time, the demand for natural gas such as metal smelting, gas power generation, and new energy vehicles is also rising. It can be said that gas is everywhere in our lives. While bringing us convenience, it also increases our safety hazards. Once the gas pipeline leaks and accumulates to a certain concentration, it is easy to cause explosion and fire once it encounters an open flame, to people's lives, property security poses a huge threat.

Gas explosion has the characteristics of fierce fire, difficult to extinguish, wide spread, destructive power, and easy to cause chain explosion. Once a gas explosion occurs, the fire spreads rapidly and is difficult to extinguish. Moreover, buildings are generally dense and pipeline laying is dense, which can easily lead to two or even multiple chain explosions, causing huge losses to people's lives and property safety.

Therefore, how to kill the gas explosion in the embryonic stage is a problem that must be solved to ensure the safety of people's lives and property. Usually, we will install a gas alarm for early warning. We will install a gas alarm at the pipeline interface and easy leakage point. Once the gas leakage warning is prompted, however, the gas pipeline is widely laid and there are many connecting ports, so it is impossible to cover all aspects. Moreover, the alarm may fail over time, and regular inspection is required manually.                                                                                   

Here,It is recommended to use a portable combustible gas detector, which is easy to carry, simple to operate, and convenient for inspection personnel to detect and confirm easy leakage points. At the same time launched a natural gas sensorTGS2611The sensor has the characteristics of small size, low power consumption, fast response and high sensitivity, which is very suitable for portable gas pipeline leak detection.

TGS2611Important parameters:

Detection principle: oxide semiconductor
