Taw qhia rau Infrared Gas Detector thiab Nws Txoj Cai Ua Haujlwm
Infrared Gas Detector yog ib lub tshuab hluav taws xob portable uas siv cov cuab yeej tshwj xeeb infrared roj tsom xam thiab muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev daws teeb meem siab, lub neej ua haujlwm ntev, thiab kev saib xyuas yooj yim. Hom kev tshawb nrhiav roj infrared no tau siv dav hauv ntau qhov kev lag luam, thiab kev tshawb nrhiav cov concentration ntawm cov nplaim hluav taws kub hnyiab tau tawg, cov pa phem thiab cov pa phem ib txwm muaj qhov tseem ceeb rau kev ruaj ntseg ntau lawm.
Lub infrared absorption spectrum tsis yog tsuas yog siv rau kev ntsuas ntawm cov pa concentration, tab sis kuj dav siv los txheeb xyuas cov qauv ntawm cov molecules sib txawv los ntawm cov yam ntxwv haum. Thiab nws muaj qhov rhiab heev, cov lus teb ceev ceev, tuaj yeem qhia tsis tu ncua hauv online, thiab tseem tuaj yeem tsim cov txheej txheem tswj hwm. Qhov kev tshawb nrhiav ib feem ntawm cov khoom siv hluav taws xob infrared feem ntau siv hauv kev lag luam muaj ob lub tshuab kho qhov muag sib txuas nrog tib cov qauv. Ib qho yog chav ntsuas thiab lwm qhov yog chav siv siv. Ob chav qhib thiab kaw txoj kev kho qhov muag ib txhij lossis hloov pauv ntawm qee lub sijhawm los ntawm kev txiav phaj.
Tom qab qhia cov roj ntsuas rau hauv chav ntsuas, lub teeb nrog lub cim wavelength ntawm cov roj ntsuas tau nqus tau, yog li txo cov teeb pom kev zoo nkag mus rau hauv qhov hluav taws xob tau txais cov roj chamber los ntawm lub ntsuas chamber. Qhov siab dua cov roj concentration, qhov tsawg lub teeb flux nkag mus rau hauv qhov chaw txais infrared; Lub luminous flux dhau los ntawm kev siv chamber yog qhov tsis tu ncua, thiab cov luminous flux nkag mus rau hauv infrared txais chamber kuj yog tas li.
Yog li ntawd, qhov siab dua qhov concentration ntawm cov pa ntsuas, qhov sib txawv ntawm cov luminous flux ntawm lub ntsuas chamber thiab cov ntaub ntawv siv chamber. Qhov sib txawv ntawm luminous flux yog npaj mus rau lub infrared txais chamber nrog ib tug tej yam amplitude ntawm periodic vibration.
Lub txais chamber muab faib ua ob halves los ntawm ib tug hlau zaj duab xis ob peb microns tuab. Lub chamber yog kaw nrog cov roj tivthaiv nrog ib tug kuj siab concentration, uas yuav nqus tau tag nrho cov infrared rays tuaj nyob rau hauv lub nqus wavelength ntau yam, yog li hloov lub pulsating lub teeb flux mus rau lub sij hawm hloov nyob rau hauv kub. Tom qab ntawd, qhov ntsuas kub hloov pauv tuaj yeem hloov pauv mus rau qhov hloov pauv siab raws li qhov sib npaug ntawm lub xeev roj, thiab siv lub capacitive sensor los ntes nws. Tom qab amplification, qhov concentration ntawm cov pa ntsuas tau qhia.
