ТАБИИЙ ГАЗ (МЕТАН) НИ АНИҚЛОВЧИ СЕНСОР (ЯЎС-СН4) НИНГ СИГНАЛИНИНГ БАРҚАРОРЛИГИ ВА СЕЛЕКТИВЛИГИНИ ТЕКШИРИШ

The work examines the operating life and the signal selectivity of the YaO'S-CH4 semiconductor methane-detecting sensor developed on the basis of a gas-sensitive material with the composition SiO2/ZnO-10%CoO+PEG. In the tests carried out, the sensor signal changed over a short interval, and the error value arising from this change is very small and does not have an appreciable effect on the results of the analysis. The selectivity of the sensors developed for natural gas was determined in the presence of H2 and CO, which occur together with natural gas in the atmospheric air from various sources. The developed sensor makes it possible to detect natural gas selectively in the presence of carbon monoxide and hydrogen.
