Taw qhia rau lub ntsuas hluav taws xob infrared thiab nws txoj haujlwm ua haujlwm
Infrared Gas Detector yog ib qho khoom siv hluav taws xob uas siv cov thev naus laus zis tshwj xeeb infrared roj tsom xam thiab nta siab precision, siab daws teeb meem, lub neej ntev, thiab kev saib xyuas yooj yim. Hom kev ntsuas roj infrared no muaj ntau yam kev siv hauv ntau qhov kev lag luam, thiab kev tshawb nrhiav cov concentration ntawm cov nplaim hluav taws kub thiab tawg, cov pa phem thiab cov pa phem yeej ib txwm muaj qhov tseem ceeb rau kev ruaj ntseg ntau lawm.
Lub infrared absorption spectrum tsis yog tsuas yog siv rau kev ntsuas roj concentration, tab sis kuj siv dav rau kev txheeb xyuas cov qauv ntawm cov molecules sib txawv los ntawm kev nqus cov yam ntxwv. 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 los yog hloov ntawm ib lub sij hawm los ntawm lub teeb txiav phaj.
Tom qab qhia cov roj ntsuas rau hauv chav ntsuas ntsuas, lub teeb nrog lub cim wavelength ntawm cov roj ntsuas tau nqus tau, yog li txo cov hluav taws xob hluav taws xob uas dhau los ntawm lub ntsuas chamber thiab nkag mus rau infrared txais chamber. Qhov siab dua cov roj concentration, qhov tsawg lub teeb flux nkag mus rau hauv qhov chaw txais infrared; Lub teeb flux dhau los ntawm qhov siv chamber yog qhov tsis tu ncua, thiab lub teeb flux nkag mus rau hauv infrared txais chamber kuj yog tas li.
Yog li ntawd, qhov siab dua qhov concentration ntawm cov roj ntsuas, qhov sib txawv ntau dua ntawm cov luminous flux dhau los ntawm cov ntsuas chamber thiab cov khoom siv chamber. Qhov sib txawv ntawm cov luminous flux no yog npaj rau ntawm qhov chaw txais infrared nrog rau qee qhov amplitude ntawm lub sijhawm vibration.
Lub txais chamber muab faib ua ob halves los ntawm ib tug hlau nyias zaj duab xis ob peb microns tuab. Lub chamber yog kaw nrog ib tug siab concentration ntawm cov tshuaj ntsuam xyuas cov roj, uas yuav nqus tau tag nrho cov infrared tawg nyob rau hauv lub absorption wavelength ntau yam, yog li transforming lub pulsating lub teeb flux mus rau lub sij hawm hloov nyob rau hauv kub. Qhov kub hloov pauv tuaj yeem hloov pauv mus rau qhov hloov pauv siab raws li qhov sib npaug ntawm lub xeev roj, thiab tom qab ntawd kuaj pom los ntawm lub ntsuas hluav taws xob capacitive. Tom qab amplification ua tiav, qhov concentration ntawm cov roj kuaj tau qhia.
