Ka ʻIke ʻana i ke Kinoea

ʻO ke sensor kinoea Non Dispersive InfraRed (NDIR) kahi ʻano mea ʻike kinoea e pili ana i nā ʻano molekole kinoea like ʻole o ka absorption koho no ka spectrum infrared kokoke, e hoʻohana ana i ka pilina ma waena o ka nui o ke kinoea a me ka ikaika o ka absorption (Lambert-Beer Law) e ʻike i nā ʻāpana kinoea a me nā ʻano. Ke hoʻohālikelike ʻia me nā ʻano sensor kinoea ʻē aʻe, e like me ke ʻano electrochemical, ke ʻano combustion catalytic a me ke ʻano semiconductor, loaʻa i nā sensor kinoea non-dispersive infrared (NDIR) nā pono o ka noi ākea, ke ola lawelawe lōʻihi, ke kiʻekiʻe o ka ʻike, ke kūpaʻa maikaʻi, ke kumukūʻai kūpono, ke kumukūʻai mālama haʻahaʻa, ka nānā pūnaewele a pēlā aku. Ua hoʻohana nui ʻia ia i ka nānā ʻana i ke kinoea, ka palekana o ke kaiapuni, ka alarm leakage, ka palekana ʻoihana, ka lāʻau lapaʻau a me ke olakino, ka hana mahiʻai a me nā ʻoihana ʻē aʻe.

1. Pale i ka ʻawaʻawa, ʻaʻohe waiho kalapona. Ke ana ka sensor CAT i kekahi mau kinoea, maʻalahi ka waiho ʻana i ke kalapona ma muli o ka lawa ʻole o ke kuni ʻana, kahi e alakaʻi ai i ka emi ʻana o ke ʻano o ke ana ʻana. Pale ʻia ke kumu kukui IR a me ke sensor e ke aniani a i ʻole ke kānana, a ʻaʻole e pili me ke kinoea, no laila ʻaʻohe kuni ʻana.

2. ʻAʻole koi ʻia ka oxygen. He sensor optical ʻo NDIR a ʻaʻole pono ka oxygen.

3. Hiki i ke ana ʻana o ka nui ke piʻi i ka 100% v / v. No ka mea, ʻo nā ʻano hōʻailona o ka sensor NDIR: i ka wā ʻaʻohe kinoea e ana ʻia, ʻo ka ikaika hōʻailona ka mea nui loa, a ʻo ke kiʻekiʻe o ka nui, ʻo ka liʻiliʻi o ka hōʻailona. No laila, ʻoi aku ka maʻalahi o ke ana ʻana i nā nui kiʻekiʻe ma mua o ke ana ʻana i nā nui haʻahaʻa.

4. Kūlana kūpaʻa lōʻihi maikaʻi loa a me ke kumukūʻai mālama haʻahaʻa. Aia ke kūpaʻa o ka sensor NDIR i ke kumu kukui. Inā koho ʻia ke kumu kukui, hiki ke hoʻohana ʻia no 2 mau makahiki me ka ʻole o ka calibration.

5. Pae mahana ākea. Hiki ke hoʻohana ʻia ʻo NDIR ma ka pae o - 40 ℃ a i 85 ℃.
