Underground Mine Gas Alarm
Gas safety detection through the whole process of mine production, processing and transportation, such as the detection of mashgas(methane), carbon monoxide (CO), hydrogen sulfide (H2S), carbon dioxide (CO2), sulfur dioxide (SO2), oxygen (O2), etc.
In coal mine processing, such as coking industry, coal gasification-synthetic ammonia, coal-based methanol, synthetic oil from coal, coal chemical co-production and other industries need to detect sulfur dioxide (SO2), hydrogen sulfide (H2S), carbon monoxide (CO2), chlorine (Cl2), ammonia (NH3) and other gases
In the underground mine field, catalytic elements are mainly used to detect the lower limit of gas explosion. At present, domestic products occupy the mainstream market, mainly measuring 100% LEL. In recent years, high-end gas detection products in the coal mine industry have gradually adopted infrared gas sensors, which have good gas selectivity and no poisoning, and the detection range can reach 100% VOL. Winsen technology underground combustible gas sensor has a wide range, multiple ranges can be selected, high sensitivity, a variety of sensors have passed the explosion-proof certificate with stable performance.
