Inzwa yegesi engeyiyo i-Dispersive InfraRed (NDIR) luhlobo lwesixhobo sokuva irhasi esekwe kwiimolekyuli zerhasi ezahlukeneyo zophawu lokufunxa olukufutshane ne-infrared spectrum, kusetyenziswa ubudlelwane phakathi koxinzelelo lwegesi kunye nokuqina kokufunxa (Lambert-Beer Law) ukuchonga amacandelo egesi. kunye nokugxininiswa.Xa kuthelekiswa nezinye iintlobo ze-gas sensors, ezifana nohlobo lwe-electrochemical, uhlobo lokutsha kunye nohlobo lwe-semiconductor, i-non-dispersive infrared (NDIR) i-gas sensors inenzuzo yesicelo esibanzi, ubomi obude benkonzo, uvakalelo oluphezulu, ukuzinza okulungileyo, indleko-esebenzayo, ixabiso eliphantsi lokugcinwa, uhlalutyo lwe-intanethi kunye nokunye.Isetyenziswe ngokubanzi kuhlalutyo lwegesi, ukukhuselwa kwendalo, i-alamu yokuvuza, ukhuseleko lwamashishini, unyango kunye nempilo, imveliso yezolimo kunye nezinye iinkalo.
1. I-Anti-poisoning, akukho i-carbon deposition.Xa isivamvo se-CAT silinganisa ezinye iigesi, kulula ukufaka i-carbon ngenxa yokungatshiswa ngokwaneleyo, okukhokelela ekunciphiseni uvakalelo lomlinganiselo.Umthombo wokukhanya we-IR kunye nenzwa ikhuselwe ngeglasi okanye isihluzi, kwaye ungaqhagamshelani negesi, ngoko akuyi kubakho ukutsha.
2. Ioksijini ayifuni.I-NDIR i-sensor optical kwaye ayifuni i-oxygen.
3. Ukugxininiswa kokulinganisa kunokufikelela kwi-100% v / v. Ngenxa yokuba iimpawu zesignali ze-NDIR sensor yilezi: xa kungekho rhasi enokulinganiswa, ubuninzi besignali bukhulu kakhulu, kwaye iphakamileyo yoxinzelelo, incinci isibonakaliso.Ngoko ke ukulinganisa imilinganiselo ephezulu kulula kunokulinganisa iindawo ezisezantsi.
4. Ukugqwesa ukuzinza kwexesha elide kunye neendleko eziphantsi zokugcinwa.Ukuzinza kwe-NDIR sensor kuxhomekeke kumthombo wokukhanya.Ngethuba nje umthombo wokukhanya ukhethiwe, kwaye unokusetyenziswa iminyaka emi-2 ngaphandle kokulinganisa
5. Uluhlu olubanzi lobushushu.I-NDIR ingasetyenziswa kuluhlu lwe-40 ℃ ukuya kwi-85 ℃
