Non Dispersive InfraRed (NDIR) sensa ya gasi ndi mtundu wa chipangizo chozindikira mpweya chomwe chimatengera mawonekedwe a mamolekyu agasi osiyanasiyana posankha mayamwidwe apafupi ndi ma infrared spectrum, pogwiritsa ntchito ubale womwe ulipo pakati pa ndende ya gasi ndi kuyamwa kwambiri (Lambert-Beer Law) kuzindikira zigawo za mpweya. ndi kukhazikika.Poyerekeza ndi mitundu ina ya masensa gasi, monga electrochemical mtundu, catalytic kuyaka mtundu ndi semiconductor mtundu, non-dispersive infrared (NDIR) mpweya masensa ali ndi ubwino ntchito lonse, moyo wautali utumiki, tilinazo kwambiri, bata wabwino, mtengo-ogwira, mtengo wotsika wokonza, kusanthula pa intaneti ndi zina zotero.Zakhala zikugwiritsidwa ntchito kwambiri pakuwunika kwa gasi, kuteteza zachilengedwe, alamu ya kutayikira, chitetezo cha mafakitale, zamankhwala ndi thanzi, ulimi ndi zina.
1. Anti-poisoning, palibe carbon deposition.Sensa ya CAT ikayesa mipweya ina, ndikosavuta kuyika kaboni chifukwa chosakwanira kuyaka, zomwe zimapangitsa kuchepa kwa chidwi cha muyeso.Gwero la kuwala kwa IR ndi sensa zimatetezedwa ndi galasi kapena fyuluta, ndipo musagwirizane ndi mpweya, kotero sipadzakhala kuyaka.
2. Oxygen safunikira.NDIR ndi sensor optical ndipo safuna mpweya.
3. Kuwerengera koyezera kumatha kufika 100% v / v. Chifukwa zizindikiro za chizindikiro cha NDIR sensor ndi: pamene palibe mpweya woti muyesedwe, mphamvu ya chizindikiro ndi yaikulu kwambiri, ndipo kukwera kwapamwamba, chizindikiro chochepa.Chifukwa chake kuyeza kuchuluka kwambiri ndikosavuta kuposa kuyeza kuchuluka kocheperako.
4. Kukhazikika kwabwino kwanthawi yayitali komanso mtengo wotsika wokonza.Kukhazikika kwa sensor ya NDIR kumadalira gwero la kuwala.Malingana ngati gwero la kuwala lisankhidwa, ndipo lingagwiritsidwe ntchito zaka 2 popanda kuwongolera
5. Wide kutentha osiyanasiyana.NDIR itha kugwiritsidwa ntchito pamitundu ya - 40 ℃ mpaka 85 ℃
