Natural gas is an excellent fuel with high calorific value, good anti-riot performance, and relatively less environmental pollution of combustion products. It is one of the less polluted energy sources in the world. At the same time, the price is low and stable. Natural gas with the same calorific value is cheaper than liquefied petroleum gas. 21%, nearly twice as cheap as electricity. Natural gas is a clean gas with stable supply and can improve air quality. Therefore, it can provide new impetus for urban economic development, promote economic prosperity and improve the environment. Due to the many advantages of natural gas, as well as my country's economic development, national strength enhancement, and improvement of understanding of natural gas utilization, my country has determined that natural gas development and utilization will be the strategic focus of energy development in the 21st century. Therefore, in recent years, my country has vigorously laid gas pipelines, and the penetration rate of national gas use has continued to rise. 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 ubiquitous in our lives. However, we must realize that the popularity of natural gas brings us not only benefits, but also huge security risks.

Natural gas is flammable and explosive. Once it leaks, it will pose a huge threat to people's lives and property. BecauseGas 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.Touching the gas pipeline may also cause two or more chain explosions. Such as this yearAt about 6: 30 a.m. on June 13, Yanhu Community, Zhangwan District, Shiyan City, Hubei Province, occurredofnatural gas explosion, official data reports eventually causedTwenty-six people were killed and 138 injured, and the surrounding buildings were in a mess. It can be seen how great the harm caused by natural gas leakage is.

Because when combustible gas accounts for a certain proportion in the air, it will explode when it encounters open fire. The lower limit of this ratio is called the lower limit of explosion (%LEL), above the upper limit of explosion, it will not explode but burn when encountering an open flame. Then in order to prevent explosions and fires, we can detect natural gas leaks through combustible gas detectors, find leaks in advance, and deal with them in time when the concentration of leaked gas is far below the lower limit of explosion, so that disasters can be avoided.

So how to choose a reliable natural gas leak detector? Tell you, like the pipeline type of natural gas leak detection requires manual inspection, you can recommend the use of portable natural gas leak detector, easy to carry, simple operation. The core component of the portable natural gas leak detector is the natural gas sensor, and a good sensor can make a good detector! Here to introduce aNatural gas sensorTGS2611，The 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.It can also be used for home gas alarms.

TGS2611It was developed by Figaro in Japan.Principle of SemiconductorNatural gas sensor，It hasLong service life, long-term stable performance, rapid responseand other characteristicsAt the same time, it also has good sensitivity to propane, butane, alcohol and other flammable gases. If it is required to resist the interference of organic solvents such as alcohol, it can be used.TGS2611-E00。
