TOP 5 CH4 Gas sensor

Combustible gas sensor module


Biogas has proven to be a very good alternative to natural energy for electricity generation and is particularly popular because it is not affected by the weather. Using biogas, basic energy needs can be provided without grid fluctuations. However, according to the German Federal Environment Agency, biogas plants have a serious accident every two weeks. Of all recorded accidents, 46 percent involved fire, making it the most common type of accident. In the other 9 percent, there was at least one explosion. The reason will be the safety standard deviation of the plant. Methane (CH 4) can react explosively with air. This poses a potentially high risk to operators of biogas plants. When the concentration of methane in the air is between 4.4 % vol and 16.5 % vol, an explosive mixture is present. Therefore, it is important to pay attention to methane changes, which can be monitored online using the CH4 gas sensor.

For example, gas monitoring in a pump house can protect people from dangerous leaks. Continuous measurements in the biogas dome storage in the double film also ensure that there are no leaks and therefore no losses. In addition, escaped methane emissions have a negative impact not only on the profitability of biogas plants, but also on the climate, since methane is about 25 times more harmful to the climate than carbon dioxide. Therefore, personnel protection and plant safety are of Paramount importance when operating a biogas plant. With MSR-Electronic’s gas warning product, you can prevent hazards. Gas sensors, controllers and warning devices are used to measure combustible and toxic gases as well as oxygen. Leaks are thus located at an early stage.
