    Sesebelisoa sa khase sa Non Dispersive InfraRed (NDIR) ke mofuta oa sesebelisoa sa kutlo ea khase se ipapisitseng le limolek'hule tse fapaneng tsa khase tse khethollang ho kenella ka har'a infrared, ho sebelisa kamano lipakeng tsa mohopolo oa khase le matla a ho monya (Lambert-Beer Law) ho khetholla likarolo tsa khase. le likhakanyo. Ha li bapisoa le mefuta e meng ea li-sensors tsa khase, joalo ka mofuta oa motlakase, mofuta oa ho chesa le mofuta oa semiconductor, li-sensors tse sa qhalaneng tsa infrared (NDIR) li na le melemo ea ts'ebeliso e pharalletseng, bophelo bo bolelele ba ts'ebeletso, kutlo e phahameng, botsitso bo botle, e bolokang chelete, litšenyehelo tse tlase tsa tlhokomelo, tlhahlobo ea inthanete joalo-joalo. E sebelisitsoe haholo tlhahlobisong ea khase, ts'ireletso ea tikoloho, alamo ea ho dutla, polokeho ea indasteri, bongaka le bophelo bo botle, tlhahiso ea temo le likarolo tse ling.

    Melemo ea sensor ea khase ea NDIR:

    1. Anti-chefo, ha ho deposition k'habone. Ha senotlolo sa CAT se lekanya likhase tse ling, ho bonolo ho beha khabone ka lebaka la mollo o sa lekanang, o lebisang ho fokotseheng ha kutlo ea litekanyo. Mohloli oa leseli le sensor ea IR li sirelelitsoe ke khalase kapa sefahleho, 'me u se ke ua ikopanya le khase, ka hona ho ke ke ha ba le mollo.

    2. Ha ho hlokahale oksijene. NDIR ke sensor ea optical ebile ha e hloke oksijene.

    3. Khakanyo ea ho lekanya e ka fihla ho 100% v / v. Hobane litšobotsi tsa lets'oao la sensor ea NDIR ke: ha ho se na khase e lokelang ho lekanyetsoa, ​​matla a lets'oao ke a maholo ka ho fetesisa, 'me ha mohopolo o phahame haholo, lets'oao le nyane. Kahoo ho lekanya libaka tse phahameng ho bonolo ho feta ho metha maemo a tlase.

    4. Ts'ebetso e ntle ea nako e telele le litšenyehelo tse tlase tsa tlhokomelo. Ho tsitsa ha sensor ea NDIR ho latela mohloli oa leseli. Hafeela mohloli oa leseli o khethiloe, 'me o ka sebelisoa lilemo tse 2 ntle le tefiso

    5. Mocheso o pharaletseng. NDIR e ka sebelisoa maemong a - 40 ℃ ho isa ho 85 ℃
