Uyini umehluko phakathi kwenzwa ye-TC kanye nenzwa ye-IR ku-CO₂ incubator?

Uma kukhuliswa amaseli, ukuze kuqinisekiswe ukukhula okufanele, izinga lokushisa, umswakama, kanye namazinga e-CO2 kudingeka kulawulwe. Amazinga e-CO2 abalulekile ngoba asiza ukulawula i-pH yendawo yokukhulisa. Uma kune-CO2 eningi kakhulu, izoba ne-asidi kakhulu. Uma ingekho i-CO2 eyanele, izoba ne-alkaline kakhulu.

KuweIsithwali se-CO2, izinga legesi ye-CO2 endaweni lilawulwa ukutholakala kwe-CO2 ekamelweni. Umbuzo uwukuthi, uhlelo “lwazi kanjani” ukuthi ingakanani i-CO2 okudingeka yengezwe? Yilapho ubuchwepheshe bezinzwa ze-CO2 buqala khona ukusebenza.

Kunezinhlobo ezimbili eziyinhloko, ngayinye inezinzuzo kanye nokungalungi kwayo:

* Ukushisa kusebenzisa i-thermal resistor ukuthola ukwakheka kwegesi. Kuyindlela engabizi kakhulu kodwa futhi ayithembekile kangako.

* Izinzwa ze-CO2 ezisebenzisa i-infrared zisebenzisa ukukhanya kwe-infrared ukuthola inani le-CO2 ekamelweni. Lolu hlobo lwenzwa lubiza kakhulu kodwa lunembe kakhulu.

Kulesi sihloko, sizochaza lezi zinhlobo ezimbili zezinzwa ngokuningiliziwe futhi sixoxe ngemiphumela engokoqobo yazo ngayinye.

Inzwa ye-CO2 Yokushisa

Ukushisa kusebenza ngokulinganisa ukumelana kukagesi emoyeni. Inzwa ngokuvamile izoba namaseli amabili, elinye lawo ligcwele umoya ovela ekamelweni lokukhula. Elinye iseli elivaliwe eliqukethe umoya obhekiselayo ekushiseni okulawulwayo. Iseli ngalinye liqukethe i-thermistor (i-thermal resistor), ukumelana kwayo okushintsha ngokushisa, umswakama, kanye nokwakheka kwegesi.

Ukubonakaliswa kwenzwa yokuqhuba ukushisa

Uma izinga lokushisa kanye nomswakama kufana kuwo womabili amaseli, umehluko wokumelana uzolinganisa umehluko ekwakhiweni kwegesi, kulokhu kukhombisa izinga le-CO2 ekamelweni. Uma kutholakala umehluko, uhlelo lucelwa ukuba lufake i-CO2 eyengeziwe ekamelweni.

Ukubonakaliswa kwenzwa yokuqhuba ukushisa.

Ama-conductor okushisa ayindlela ehlukile engabizi kakhulu kunezinzwa ze-IR, esizoxoxa ngazo ngezansi. Kodwa-ke, azizi ngaphandle kwezithiyo zazo. Ngenxa yokuthi umehluko wokumelana ungathinteka ezinye izici ngaphandle kwamazinga e-CO2 kuphela, izinga lokushisa kanye nomswakama ekamelweni kufanele kuhlale kungaguquguquki ukuze uhlelo lusebenze kahle.

Lokhu kusho ukuthi njalo uma umnyango uvula futhi izinga lokushisa nomswakama kushintshashintsha, uzogcina ufundile ngendlela enganembile. Eqinisweni, ukufundwa ngeke kube okunembile kuze kube yilapho umkhathi uzinza, okungathatha isigamu sehora noma ngaphezulu. Ama-thermal conductor angase alungele ukugcinwa kwesikhathi eside kwama-culture, kodwa awafaneleki kangako ezimweni lapho ukuvuleka kweminyango kuvame khona (ngaphezu kwesisodwa ngosuku).

Izinzwa ze-CO2 ze-infrared

Izinzwa ze-infrared zibona inani legesi ekamelweni ngendlela ehluke ngokuphelele. Lezi zinzwa zithembele eqinisweni lokuthi i-CO2, njengezinye izinzwa, imunca ubude besikhathi bokukhanya obuthile, obuyi-4.3 μm ukuze kube nembile.

Ukubonakaliswa kwenzwa ye-Infrared

Inzwa ingathola ukuthi ingakanani i-CO2 emkhathini ngokulinganisa ukuthi kungakanani ukukhanya okungu-4.3 μm okudlula kuwo. Umehluko omkhulu lapha ukuthi inani lokukhanya elitholakele alixhomekile kunoma yiziphi ezinye izinto, njengokushisa nomswakama, njengoba kunjalo ngokumelana nokushisa.

Lokhu kusho ukuthi ungavula umnyango izikhathi eziningi ngokuthanda kwakho futhi inzwa izohlala iletha ukufundwa okunembile. Ngenxa yalokho, uzoba nezinga elihambisanayo le-CO2 ekamelweni, okusho ukuzinza okungcono kwamasampula.

Nakuba intengo yezinzwa ze-infrared yehlile, zisamelela enye indlela ebiza kakhulu esikhundleni sokuqhutshwa kokushisa. Kodwa-ke, uma ucabangela izindleko zokuntuleka kokukhiqiza lapho usebenzisa inzwa yokuqhutshwa kokushisa, ungase ube necala lezezimali lokusebenzisa inketho ye-IR.

Zombili izinhlobo zezinzwa ziyakwazi ukubona izinga le-CO2 ekamelweni lokufukamela. Umehluko omkhulu phakathi kwalezi ezimbili ukuthi inzwa yokushisa ingathinteka yizici eziningi, kanti njengenzwa ye-IR ithintwa yizinga le-CO2 lodwa.

Lokhu kwenza izinzwa ze-IR CO2 zibe nembaba kakhulu, ngakho-ke zingcono kakhulu ezimweni eziningi. Zivame ukuza nentengo ephezulu, kodwa ziya ngokuya zibiza kancane njengoba isikhathi siqhubeka.

Vele uchofoze isithombe beseThola i-incubator yakho ye-CO2 sensor ye-IR manje!
