Dab tsi yog cov qauv kev tshawb nrhiav ntawm cov khoom siv hluav taws xob hluav taws xob
Lub catalytic combustion hom combustible gas detector siv cov kev hloov ntawm refractory hlau platinum hlau tom qab cua sov los txiav txim siab concentration ntawm combustible gases. 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, uas ua rau ib tug hloov nyob rau hauv lub resistivity ntawm platinum hlau. Qhov kev hloov pauv no yog siv los txiav txim siab qhov concentration ntawm cov pa roj combustible. cov
Lub infrared optical combustible gas detector siv ib tug infrared sensor los ntes hydrocarbon combustible gases nyob rau hauv lub site ib puag ncig los ntawm lub absorption txoj cai ntawm ib tug infrared lub teeb qhov chaw. Hom kev ntes no siv lub patented "cov ntsaws me me thiab ua si hloov tau" infrared optical sensor, uas muaj kev ruaj ntseg ntev thiab kev tu ncua sij hawm tsawg. Infrared gas sensors yog lwm txoj hauv kev zoo rau cov tshuaj catalytic combustion sensors hauv qee qhov chaw ntsuas. cov
Ob hom detectors muaj lawv qhov tshwj xeeb daim ntawv thov ib puag ncig thiab zoo. Piv txwv li, catalytic detectors yog haum rau ib puag ncig uas nquag raug rau catalytic toxic gases thiab cov pa roj carbon monoxide siab, thaum infrared optical detectors yog tsim nyog rau cov pa oxygen tsis txaus ib puag ncig thiab ib puag ncig uas nrhiav tau nyuaj ua tiav. Cov xwm txheej ntawm daim ntawv thov muaj xws li offshore lag luam platforms thiab drilling platforms, refineries, petrochemical nroj tsuag, compressed natural gas thiab liquefied gas kho, dej khib nyiab, tshuaj nroj tsuag, twj tso kua mis, thiab thermal fais fab nroj tsuag.
