Combustible gas detector broadcast edit Discussion 10 upload video Detectors for txiav txim siab qhov concentration ntawm combustible gases Synonyms Combustible gas detector (combustible gas detector) feem ntau yog hais txog combustible gas detector combustible gas detectors yog detectors uas teb rau ib los yog ntau yam combustible gas concentrations. Muaj ob hom kev ntsuas roj hluav taws xob: hom catalytic thiab infrared optical hom. Lub catalytic combustible gas detector siv qhov kev hloov pauv ntawm cov hlau refractory platinum hlau los ntsuas qhov concentration ntawm cov roj combustible. Thaum cov roj combustible nkag mus rau hauv lub ntes, nws ua rau oxidation cov tshuaj tiv thaiv (flameless combustion) nyob rau saum npoo ntawm platinum hlau, thiab lub tshav kub generated tsub kom qhov kub ntawm lub platinum hlau, thiab lub resistivity ntawm platinum hlau hloov. Hom infrared optical siv lub infrared sensor los xyuas cov roj hydrocarbon combustible gas nyob rau hauv lub tshav pob ib puag ncig los ntawm lub absorption txoj cai ntawm lub teeb infrared.
