Non Dispersive InfraRed (NDIR) gas sensor yog ib hom roj sensing ntaus ntawv uas raws li cov roj molecules sib txawv 'tus yam ntxwv ntawm kev xaiv haum rau ze infrared spectrum, siv kev sib raug zoo ntawm roj concentration thiab nqus siv zog (Lambert-Beer Law) los txheeb xyuas cov roj Cheebtsam. thiab concentrations.Piv nrog rau lwm hom roj sensors, xws li electrochemical hom, catalytic combustion hom thiab semiconductor hom, non-dispersive infrared (NDIR) gas sensors muaj qhov zoo ntawm daim ntawv thov dav, lub neej ntev kev pab cuam, siab rhiab heev, zoo stability, nqi-zoo, tsis tshua muaj nqi txij nkawm, kev txheeb xyuas online thiab lwm yam.Nws tau siv dav hauv kev tsom xam roj, kev tiv thaiv ib puag ncig, lub tswb nrov, kev nyab xeeb kev lag luam, kev kho mob thiab kev noj qab haus huv, kev ua liaj ua teb thiab lwm yam kev lag luam.
1. Anti-poisoning, tsis muaj carbon deposition.Thaum CAT sensor ntsuas qee cov pa roj carbon monoxide, nws yooj yim rau tso cov pa roj carbon monoxide vim tias tsis muaj kev sib txuas, uas ua rau txo qis ntawm kev ntsuas rhiab heev.IR lub teeb pom kev zoo thiab sensor yog tiv thaiv los ntawm iav los yog lim, thiab tsis txhob sib cuag nrog roj, yog li yuav tsis muaj combustion.
2. Tsis tas yuav tsum muaj pa.NDIR yog optical sensor thiab tsis xav tau oxygen.
3. Kev ntsuas qhov siab tuaj yeem ncav cuag 100% v / v. Vim tias cov yam ntxwv ntawm cov teeb liab ntawm NDIR sensor yog: thaum tsis muaj roj los ntsuas, lub teeb liab siv ntau tshaj plaws, thiab qhov siab dua qhov siab, qhov teeb liab me dua.Yog li ntsuas cov concentrations siab yog yooj yim dua li ntsuas cov concentrations tsawg.
4. Kev ruaj ntseg zoo rau lub sij hawm ntev thiab tsis tshua muaj nqi tu.Kev ruaj ntseg ntawm NDIR sensor nyob ntawm lub teeb ci.Tsuav yog xaiv qhov teeb pom kev zoo, thiab nws tuaj yeem siv tau 2 xyoos yam tsis muaj calibration
5. Dav kub ntau yam.NDIR tuaj yeem siv nyob rau hauv thaj tsam ntawm -40 ℃ to 85 ℃
