ʻO ka mea ʻike kinoea Non Dispersive InfraRed (NDIR) kahi ʻano mea ʻike kinoea e pili ana i nā ʻano molekole kinoea like ʻole o ka hoʻopili koho ʻana no ka spectrum infrared kokoke, me ka hoʻohana ʻana i ka pilina ma waena o ke kinoea a me ka ikaika absorption (Lambert-Beer Law) e ʻike i nā ʻāpana kinoea. a me ka noonoo ana.Hoʻohālikelike ʻia me nā ʻano mea ʻike kinoea ʻē aʻe, e like me ke ʻano electrochemical, catalytic combustion type a me semiconductor type, non-dispersive infrared (NDIR) gas sensors i nā pono o ka noi ākea, ke ola lawelawe lōʻihi, ka naʻau kiʻekiʻe, ke kūpaʻa maikaʻi, ka uku-pono, ka uku mālama haʻahaʻa, ka nānā ʻana ma ka pūnaewele a pēlā aku.Ua hoʻohana nui ʻia i ka nānā ʻana i ke kinoea, ka mālama ʻana i ke kaiapuni, ka leakage alarm, ka palekana ʻoihana, ka lāʻau lapaʻau a me ke olakino, ka hana mahiʻai a me nā māla ʻē aʻe.
1. Anti-poisoning, ʻaʻohe deposition carbon.Ke ana ʻo CAT sensor i kekahi mau kinoea, maʻalahi ka waiho ʻana i ke kalapona ma muli o ka lawa ʻole o ka puhi ʻana, e alakaʻi ana i ka emi ʻana o ka naʻau.Mālama ʻia ke kumu kukui IR a me ka sensor e ke aniani a i ʻole kānana, a ʻaʻole pili me ke kinoea, no laila ʻaʻohe ahi.
2. ʻAʻole koi ʻia ka oxygen.ʻO NDIR kahi mea ʻike maka a ʻaʻole koi i ka oxygen.
3. Hiki i ke ana ana ke hiki i ka 100% v / v. No ka mea, o na ano hoailona o ka NDIR sensor: ke ana ole ia ke kinoea, oi aku ka nui o ka hoailona, a o ke kiekie o ka hoailona, o ka mea liilii.No laila, ʻoi aku ka maʻalahi o ke ana ʻana i nā haʻahaʻa haʻahaʻa.
4. Ke kūpaʻa lōʻihi maikaʻi a me ka uku mālama haʻahaʻa.ʻO ke kūpaʻa o ka sensor NDIR e pili ana i ke kumu kukui.Ke koho ʻia ke kumu kukui, a hiki ke hoʻohana ʻia i 2 mau makahiki me ka ʻole calibration
5. Laulā wela wela.Hiki ke hoʻohana ʻia ka NDIR ma ka laulā o - 40 ℃ a 85 ℃
