Ndeupi musiyano uripo pakati pe IR neTC CO2 sensor?

Paunenge uchikura sero tsika, kuti uve nechokwadi chekukura kwakaringana, tembiricha, hunyoro, uye CO2 mazinga anofanirwa kudzorwa. CO2 mazinga akakosha nekuti anobatsira kudzora pH yetsika yepakati. Kana paine CO2 yakawandisa, inozowedzera acidic. Kana pasina CO2 yakakwana, inozowedzera alkaline.

Mune CO2 incubator yako, mwero weCO2 gasi mukati mepakati unodzorwa nekupihwa kwe CO2 mukamuri. Mubvunzo ndewokuti, hurongwa "hunoziva" sei CO2 inoda kuwedzerwa? Apa ndipo panopinda CO2 sensor tekinoroji.

Kune mhando mbiri huru, imwe neimwe iine zvayakanakira nezvayakaipira:

* Thermal conductivity inoshandisa iyo inopisa resistor kuona gasi kuumbwa. Ndiyo sarudzo isingadhure asi zvakare haina kuvimbika.

* Infrared CO2 sensors inoshandisa infrared light kuona huwandu hwe CO2 mukamuri. Iyi mhando ye sensor inodhura zvakanyanya asi yakanyanya kunaka.

Mune ino positi, isu tichatsanangura aya maviri marudzi e sensor mune zvakadzama uye tokurukura zvinoshanda zveimwe neimwe.

Thermal Conductivity CO2 Sensor

Thermal conductivity inoshanda nekuyera kudzivirira kwemagetsi kuburikidza nemhepo. Iyo sensor inowanzo sanganisira masero maviri, rimwe rawo rizere nemhepo kubva mukamuri yekukura. Rimwe racho isero rakavharwa rine mhepo yereferensi pane tembiricha inodzorwa. Sero rega rega rine thermistor (thermal resistor), kupikisa kwayo kunoshanduka netembiricha, mwando, uye gasi kuumbwa.

Chiratidziro cheiyo thermal conductivity sensor

Kana tembiricha uye hunyoro zvakafanana kune ese maviri maseru, mutsauko wekupikisa uchayera mutsauko mukuumbwa kwegasi, mune iyi kesi inoratidza chiyero che CO2 mukamuri. Kana mutsauko ukaonekwa, sisitimu inokurudzirwa kuwedzera imwe CO2 mukamuri.

Chiratidziro cheiyo thermal conductivity sensor.

Thermal conductors inzira isingadhure kune IR sensors, yatichakurukura pazasi. Zvisinei, havauyi vasina zvipingamupinyi zvavo. Nemhaka yekuti kusiyana kwekupikisa kunogona kukanganiswa nezvimwe zvinhu kunze kwemazinga eCO2 chete, tembiricha uye humidity mukamuri inofanira kugara iri nguva dzose kuti sisitimu ishande nemazvo.

Izvi zvinoreva kuti pese panovhurwa gonhi uye tembiricha nehunyoro zvichichinja, unozopedzisira wava nekuverenga kusiri iko. Kutaura zvazviri, kuverenga kwacho hakuzove kwakarurama kutozosvikira mamiriro ekunze agadzikana, izvo zvinogona kutora hafu yeawa kana kupfuura. Thermal conductors inogona kunge yakanakira kuchengetedza kwenguva refu yetsika, asi haina kukodzera kune mamiriro apo kuvhurika kwegonhi kunowanzoitika (kanopfuura kamwe chete pazuva).

Infrared CO2 Sensors

Infrared sensors inoona huwandu hwegasi mukamuri nenzira yakasiyana zvachose. Aya masensa anovimba nenyaya yekuti CO2, semamwe magasi, inotora imwe wavelength yechiedza, 4.3 μm kuti ive chaiyo.

Iyo inomiririra ye infrared sensor

Iyo sensor inogona kuona kuti yakawanda sei CO2 iri mumhepo nekuyera kuti yakawanda sei 4.3 μm mwenje inopfuura nepairi. Musiyano mukuru pano ndewekuti kuwanda kwechiedza chakaonekwa hachitsamiri pane chero zvimwe zvinhu, senge tembiricha uye humidity, sezvazvakaita nekupisa kwekupisa.

Izvi zvinoreva kuti iwe unogona kuvhura musuwo kakawanda sezvaunoda uye sensor inogara ichipa kuverenga kwakaringana. Nekuda kweizvozvo, iwe unenge uine yakanyanya kuenderana nhanho yeCO2 mukamuri, zvichireva kugadzikana kurinani kwemasampuli.

Kunyangwe mutengo we infrared sensors wadzikira, ivo vachiri kumiririra imwe pricier kune yekupisa conductivity. Nekudaro, kana iwe ukafunga mutengo wekushaikwa kwechigadzirwa kana uchishandisa thermal conductivity sensor, unogona kunge uine nyaya yemari yekuenda neiyo IR sarudzo.

Mhando mbiri dzema sensors dzinokwanisa kuona huwandu hwe CO2 mukamuri yeincubator. Musiyano mukuru pakati pezviviri ndewekuti tembiricha sensor inogona kukanganiswa nezvinhu zvakawanda, nepo IR sensor inobatwa neiyo CO2 level chete.

Izvi zvinoita kuti IR CO2 sensors iwedzere kurongeka, saka ivo vari nani mumamiriro mazhinji. Ivo vanowanzouya nemutengo wepamusoro, asi ivo vari kudhura zvishoma nekufamba kwenguva.

Ingobaya mufananidzo uyeTora yako IR sensor CO2 incubator izvozvi!
