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.

Is the Dust Sensor Wired when Shipped?

Laser dust is wired, infrared dust is not wired.

How to Install and Place the Infrared Dust Sensor?

It must be installed vertically. Keep away from artificial air flow such as fans. When used in air purifiers, the front and rear of the fan cannot be installed. Optionally install it on one side of the shell, but keep vents on the shell to ensure that the external air can diffuse in.

What is the Difference Between Semiconductor Sensors and Electrochemical Sensors?

There is no good linear correspondence between the gas concentration and voltage of the semiconductor sensor, and it is generally only used for fixed-point calibration products; there is a good linear correspondence between the gas concentration and the output current of the electrochemical sensor, and can be made into quantitative detection products.
