Xaiv Gas Detectors Raws li Gases yuav tsum tau kuaj
Portable toxic thiab teeb meem roj ntes yog ib qho ntawm cov khoom siv feem ntau siv hauv qee qhov chaw txaus ntshai. Nws yog ib qho cuab yeej siv lub cev lossis tshuaj lom neeg ntawm cov roj nws tus kheej los hloov mus rau hauv cov teeb liab hluav taws xob los ntawm kev siv tshuab photoelectric, yog li ntsuas cov roj concentration. Nws lub ntsiab tivthaiv yog gas sensor. Feem ntau ntawm cov pa roj sensors muaj xws li electrochemical sensors, catalytic combustion sensors, photoionization detectors, semiconductor sensors, thiab lwm yam. Muaj ntau cov pa roj uas tuaj yeem kuaj tau los ntawm cov pa phem thiab cov pa phem, thiab peb yuav tsum xaiv cov khoom siv roj los siv raws li cov roj uas peb xav pom.
Xaiv raws li hom roj uas raug kuaj pom:
Vim muaj ntau txoj kev tshawb nrhiav, txhua qhov xwm txheej yuav tsum tau txiav txim siab. Piv txwv li, thaum kuaj pom methane thiab lwm yam tsis muaj tshuaj lom hydrocarbons, lub EM-50 methane detection transmitter tsau methane gas detector yog tsim nyog.
Xaiv los ntawm hom sensor:
Ib qho cuab yeej uas tsis tuaj yeem hloov pauv lub teeb tsa sensor lossis ntxiv lossis tshem tawm cov sensors yuav yog qhov tsis xws luag. Thaum xaiv tus ntes, yam xws li seb lub sensor puas tuaj yeem hloov ntawm qhov chaw thiab seb nws puas nyuaj rau ntxiv cov sensors yuav tsum tau txiav txim siab. Yog tias hom pa phem nyob hauv ib puag ncig uas raug kuaj pom tau raug lees paub, xaiv ib lub sensor tshwj xeeb yog txoj kev nyab xeeb thiab nyab xeeb tshaj plaws.
Xaiv ntawm diffusion los yog twj tso kua mis:
Yog tias nws nyob hauv qhov chaw qhib, tuaj yeem siv lub tshuab hluav taws xob diffusion. Yog tias nws nyob hauv qhov chaw kaw, yuav tsum xaiv lub ntsuas roj ntau nrog lub twj tso kua mis built-in. Yog tias nws yog siv rau kev kuaj pom thaum muaj xwm txheej ceev, ib qho cuab yeej nrog lub twj tso kua mis nqus lub sij hawm luv luv, yuav tsum tau siv lub siab rhiab heev thiab kev daws teeb meem, uas tuaj yeem yooj yim txiav txim siab qhov taw tes ntawm qhov xau.
