Kodi Electrochemical Gas Sensor ndi chiyani

Chifukwa Chiyani Muzigwiritsa Ntchito Sensor ya Gasi ya Electrochemical?

Sensor ya electrochemical ndi imodzi mwazinthu zofunika kwambiri pakupangasensa ya gasi. Electrochemistry makamaka imatanthawuza mfundo zake zogwirira ntchito.

Zimagwira ntchito popanga mayendedwe amankhwala ndi mpweya woyezedwa ndikupanga chizindikiro chamagetsi molingana ndi kuchuluka kwa gasi.

Masensa ambiri amagetsi a electrochemical ali mumayendedwe ophatikizika, ndipo ma molekyulu agasi omwe ali m'malo ozungulira mwachilengedwe amayenda m'mabowo ang'onoang'ono kutsogolo kwa sensa kuti alowe sensa. Zida zina zimakhala ndi mpope wa mpweya kuti zikokere zitsanzo za mpweya ndi mpweya mu sensa, ndikuziyang'anira.

Pofuna kupewa chikoka, kuonetsetsa kulondola kwa kuwunika, mu pores wa Hoi gawo ndi mpweya permeable nembanemba chotchinga nthunzi madzi, ndi zosafunika zina mu sensa. Muyeso woyezera komanso kukhudzidwa kwa sensa kumatha kusinthidwa ndikusintha kukula kwa cholowetsa mpweya panthawi yopanga.

Bowo lalikulu la mpweya limatha kupititsa patsogolo kukhudzidwa ndi kusintha kwa sensa, pomwe cholowera chaching'ono cha mpweya chimachepetsa kukhudzika ndi kukonza, koma kumawonjezera kuchuluka kwa muyeso.

Yesani Electrochemical Gas Sensor yopangidwa ndi HENGKO Manufacture

Pakali pano, masensa electrochemical akhala ankagwiritsa ntchito chitetezo chakudya, kusanthula kwachilengedwenso, mankhwala moyo, kuwunika chilengedwe, etc. Electrochemical masensa amatha kudziwa ozoni, formaldehyde, mpweya monoxide, ammonia, hydrogen sulfide, sulfure dioxide, nayitrogeni dioxide, mpweya ndi mpweya wina. . HENGKO ili ndi masensa osiyanasiyana a electrochemical, monga masensa okosijeni, masensa a hydrogen sulfide, masensa a carbon monoxide, masensa ammonia, masensa a carbon dioxide, etc.

Komanso, palizimbale zosaphulika, zipolopolo za mpweya wa sensa,ma module a sensa ya gasi, ma probe sensor sensors, chowunikira gasizida za alamu zomveka komanso zopepuka, ma module otulutsa mpweya, zida zamagetsi zamagetsi zamagetsi, ndi zina zambiri kuti zikwaniritse zosowa za mafakitale osiyanasiyana.

Sensa yabwino kwambiri ya electrochemical ndi sensor yomwe imazindikira mpweya. Kupatula apo, sensa yoyamba ya electrochemical idagwiritsidwa ntchito powunikira mpweya. Ili ndi kusankha bwino, kudalirika komanso moyo wautali. Masensa ena a electrochemical amatha kusokonezedwa ndi mpweya wina. Deta yosokoneza imawerengedwa pogwiritsa ntchito mpweya wochepa kwambiri.

Muzochita zogwiritsidwa ntchito, kusokoneza kusokonezeka kungakhale kwakukulu kwambiri, komwe kungayambitse kuwerengera zabodza kapena ma alarm abodza. Hengge kuphulika-umboni mkulu-mwatsatanetsatane odana ndi kusokoneza mafakitale mpweya kachipangizo, ntchito bwino, khola ndi odalirika ntchito, unsembe osasunthika ndi kukonza, ntchito yosavuta, amphamvu odana kusokoneza, osiyanasiyana: 0-30% VOL , kulondola: ± 3% (FS ) , kubwereza Magwiridwe: ≤ 2% , chisankho: 1% VOL , nthawi yoyankha: ≤ masekondi 30, mlingo wa chitetezo ukhoza kufika IP65 , IP66 .

Electrochemical sensorsali ndi zofunikira zochepa kwambiri zogwiritsira ntchito mphamvu, ndipo pakati pa mitundu yonse ya masensa a gasi, mphamvu yake yogwiritsira ntchito mphamvu ndiyotsika kwambiri. Chifukwa chake, sensa iyi imagwiritsidwa ntchito kwambiri m'malo ochepa. Nthawi zambiri, moyo wa masensa a electrochemical ndi zaka 1-3. Komabe, kutalika kwa moyo wa sensayo kumadalira makamaka kuipitsidwa kwa chilengedwe, kutentha ndi chinyezi chomwe chimawonekera. Chifukwa chake, kuyang'ana nthawi zonse ndikukonza ma sensor a electrochemical ndi njira zowonjezeretsa moyo wawo.

Kodi mukudziwa Momwe Electrochemical Sensor Imagwirira Ntchito?

Pamafunso awa, choyamba tiyenera kudziwa zina zofunika monga mfundo, zigawo, masitepe ogwirira ntchito

muyenera kudziwanso mitundu ina yotchuka ya masensa a electrochemical. ndiye lolani tsatanetsatane motere:

Masensa a Electrochemical amagwiritsidwa ntchito kwambiri pozindikira ndikuwerengera zinthu zosiyanasiyana zamankhwala pogwiritsa ntchito mfundo za electrochemistry. Nazi mwachidule momwe amagwirira ntchito:

1. Mfundo Yoyambira:

Masensa a Electrochemical amagwira ntchito poyeza mphamvu yamagetsi kapena yapano yomwe imabwera chifukwa cha kachitidwe ka mankhwala pa electrode pamwamba.

2. Zigawo Zoyambira:

* Working Electrode (WE): Apa ndipamene chidwi cha electrochemical chimachitika. Zakuthupi ndi zapamtunda za electrode iyi ndizofunikira kuti sensa igwire ntchito.
* Reference Electrode (RE): Imapereka chidziwitso chokhazikika chomwe mphamvu ya elekitirodi yogwira ntchito imayesedwa.
* Counter Electrode (CE kapena Auxiliary Electrode): Imamaliza kuzungulira kwamagetsi, kulola kuti pakali pano kuyenda pakati pa maelekitirodi ogwira ntchito ndi owerengera.
* Electrolyte: Sing'anga yomwe imathandizira kuyenda kwa ma ion ndikuthandizira machitidwe a electrochemical pamagetsi.

3. Njira zogwirira ntchito:

* Kuwonekera kwa Analyte: Pamene molekyu yomwe mukufuna (kapena analyte) ikumana ndi electrode yomwe ikugwira ntchito, imakumana ndi electrochemical reaction - mwina imakhala oxidized (kutaya ma elekitironi) kapena kuchepetsedwa (ikupeza ma electron).
* Electron Transfer: Kachitidwe ka electrochemical uku kumaphatikizapo kusamutsa ma elekitironi pakati pa analyte ndi electrode, kupanga chizindikiro chamagetsi choyezeka.
* Kuyeza kwa Signal: Chizindikiro chamagetsi chopangidwa (mwina chomwe chingakhale chosiyana kapena chapano) chimayezedwa ndi chitsimikiziro chokhazikika choperekedwa ndi ma elekitirodi.
* Kutanthauzira kwa Deta: Kukula kwa chizindikiro chamagetsi ichi kumagwirizana mwachindunji ndi kuchuluka kwa analyte. Poyerekeza chizindikirocho ndi ma curve calibration kapena kugwiritsa ntchito machitidwe odziwika a analyte, kukhazikika kwake kungadziwike.

4. Mitundu ya Sensor Electrochemical:

* Ma sensor a Potentiometric: Yezerani kusiyana komwe kungakhalepo pakati pa ma elekitirodi ogwirira ntchito ndi ofotokozera. pH mita ndi zitsanzo wamba.
* Masensa a Amperometric: Yezerani zomwe zikuchitika chifukwa cha ma electrochemical reaction of the analyte pa electrode yogwira ntchito. Glucose mita nthawi zambiri amagwiritsa ntchito masensa amperometric.
* Masensa a Impedimetric: Yezerani kusinthika kapena kukana kusintha kwa ma electrochemical cell mukakumana ndi analyte.
* Masensa a Conductometric: Yezerani kusinthika kwa njira ya electrolyte mukakumana ndi analyte.

5. Ubwino wa Electrochemical Sensors:

* Kuzindikira kwakukulu komanso kusankha.
* Nthawi yoyankha mwachangu.
* Kutha kugwira ntchito m'magawo amadzimadzi ndi gasi.
* Kutha kugwira ntchito mu zitsanzo za turbid kapena zamitundu.
* Nthawi zambiri amanyamula komanso oyenera kusanthula zenizeni zenizeni.

6. Zolepheretsa:

* Masensa amatha kuipitsidwa kapena kuipitsidwa ndi zoipitsa, zomwe zimakhudza momwe amagwirira ntchito.
* Kusunthika muzowonjezera ma electrode kumatha kubweretsa zolakwika.
* Zina zimafunikira kusanjidwa nthawi ndi nthawi kuti zikhale zolondola.

Ponseponse, magwiridwe antchito a masensa a electrochemical amadalira kapangidwe kake, zida zomwe zimagwiritsidwa ntchito, komanso momwe ma electrochemical amachitira ndi chowunikira chandamale. Ntchito zawo zambiri zimayambira pakuwunika kwachilengedwe komanso kuwunika kwachipatala mpaka kutsimikizika kwazakudya ndi kupitilira apo.
