OVERVIEW OF GAS ANALYZERS FOR METHANE

Depressurization of gas-using equipment can lead to an explosion of the gas-air mixture or to a fire. Gas analyzers are used for timely detection of gas leaks. This article contains an overview of gas analyzers that differ in their design, functionality and in the operating principle of detecting elements (sensors). It is noted that for detection of methane leaks (including natural gas) the most effective detectors (sensors) based on the principles of thermal catalysis, absorption of infrared radiation, changes in electrical conductivity are the most effective in terms of sensitivity and speed.
