Yintoni i-Electrochemical Gas Sensor

Kutheni Usebenzisa I-Electrochemical Gas Sensor?

I-sensor ye-electrochemical yenye yezona zinto zibalulekileyo kwi-isivamvo segesiI-Electrochemistry ibhekisa ikakhulu kumgaqo wayo wokusebenza.

Isebenza ngokuvelisa i-chemical reaction kunye negesi elinganisiweyo kwaye ivelise isignali yombane ehambelana noxinzelelo lwegesi.

Uninzi lwee-sensors zegesi ze-electrochemical zikwimo yokusasazwa, kwaye iimolekyuli zesampuli zegesi kwindawo engqongileyo zihamba ngokwemvelo ngemingxunya emincinci engaphambili kwe-sensor ukuze zingene kwi-sensor. Ezinye izixhobo ziya kuba nepompo yomoya yokutsala iisampulu zomoya kunye negesi kwi-sensor, kwaye emva koko ziyibeke esweni.

Ukuphepha impembelelo, ukuqinisekisa ukuchaneka kokubeka esweni, kwiimbobo zenxalenye yeHoi kunye nomqobo we-membrane ongena ngegesi kumphunga wamanzi, kunye nokunye ukungcola kwi-sensor. Uluhlu lokulinganisa kunye novakalelo lwe-sensor lunokutshintshwa ngokulungelelanisa ubungakanani bokungena komoya ngexesha loyilo.

Umngxuma omkhulu womoya unokuphucula uvakalelo kunye nesisombululo sesenzi, ngelixa i-inlet encinci yomoya inciphisa uvakalelo kunye nesisombululo, kodwa yonyusa uluhlu lokulinganisa.

Zama i-Electrochemical Gas Sensor evela kwi-HENGKO Manufacture

Okwangoku, ii-sensors ze-electrochemical zisetyenziswa kakhulu kukhuseleko lokutya, uhlalutyo lwebhayoloji, amayeza obomi, ukujonga okusingqongileyo, njl. Ii-sensors ze-electrochemical zinokubona i-ozone, i-formaldehyde, i-carbon monoxide, i-ammonia, i-hydrogen sulfide, i-sulfur dioxide, i-nitrogen dioxide, i-oxygen kunye nezinye iigesi. I-HENGKO inee-sensors ezahlukeneyo ze-electrochemical, ezifana nee-sensors ze-oxygen, ii-sensors ze-hydrogen sulfide, ii-sensors ze-carbon monoxide, ii-sensors ze-ammonia, ii-sensors ze-carbon dioxide, njl.

Ukongeza, kukhoiidiski ezithintela ukuqhuma, iigobolondo zokuphefumla zesenzi segesi,iimodyuli zesensor yegesi, iiprobe zesensor yegesi, isixhobo sokubona igesiIzixhobo ze-alamu yesandi kunye neyokukhanya, iimodyuli zokuhambisa igesi, izixhobo ze-alamu ye-sensor yegesi, njl.njl. ukuhlangabezana neemfuno zamashishini ahlukeneyo.

Eyona sensor ye-electrochemical ilungileyo yi-sensor ebona i-oksijini. Kaloku, i-sensor ye-electrochemical yokuqala yasetyenziswa okokuqala ukujonga i-oksijini. Inokukhetha okulungileyo, ithembekile kwaye ihlala ixesha elide. Ezinye ii-sensor ze-electrochemical zisengozini yokuphazamiseka kwezinye iigesi. Idatha yokuphazamiseka ibalwa kusetyenziswa amazinga aphantsi egesi.

Kwizicelo ezisebenzayo, uxinzelelo lokuphazamiseka lunokuba phezulu kakhulu, nto leyo enokubangela ukufundwa okungekhoyo okanye ii-alamu zobuxoki. I-Hengge i-Hengge i-high-proof anti-interference industrial sensor, ukusebenza kakuhle, ukusebenza okuzinzileyo nokuthembekileyo, ukufakwa okuzinzileyo kunye nokugcinwa, ukusebenza okulula, ukulwa nokuphazamiseka okunamandla, uluhlu: 0-30%VOL, ukuchaneka: ± 3% (FS), ukuphinda Ukusebenza: ≤ 2%, isisombululo: 1% VOL, ixesha lokuphendula: ≤ imizuzwana engama-30, inqanaba lokhuseleko linokufikelela kwi-IP65, IP66.

Izinzwa ze-electrochemicalzinemfuno ephantsi kakhulu yamandla okusebenza, kwaye phakathi kwazo zonke iintlobo zeenzwa zegesi, ukusetyenziswa kwamandla ayo kuphantsi kakhulu. Ke ngoko, le sensor isetyenziswa kakhulu kwindawo encinci. Ngokubanzi, ixesha lokuphila kweenzwa ze-electrochemical yiminyaka eli-1-3. Nangona kunjalo, ixesha lokuphila kwenzwa lixhomekeke kakhulu kungcoliseko lokusingqongileyo, ubushushu kunye nokufuma evezwe kuyo. Ke ngoko, ukufunyanwa rhoqo kunye nokugcinwa kweenzwa ze-electrochemical ngamanyathelo asebenzayo okwandisa ubomi bazo.

Ngaba uyazi ukuba isebenza njani i-Electrochemical Sensor?

Kule mibuzo, kuqala kufuneka sazi ulwazi olusisiseko olufana nomgaqo, izinto ezisetyenziswayo, amanyathelo okusebenza

Kwakhona kufuneka wazi ezinye iintlobo ezidumileyo zee-electrochemical sensors. Emva koko masijonge iinkcukacha ngolu hlobo lulandelayo:

Ii-sensors ze-electrochemical zisetyenziswa kakhulu ekufumaneni nasekulinganiseni izinto ezahlukeneyo zeekhemikhali ngokusebenzisa imigaqo ye-electrochemistry. Nantsi ingcaciso ngokubanzi yendlela ezisebenza ngayo:

1. Umgaqo osisiseko:

Izinzwa ze-electrochemical zisebenza ngokulinganisa amandla ombane okanye umbane ovela ngenxa yempendulo yekhemikhali kumphezulu we-electrode.

2. Izinto ezisisiseko:

* I-Electrode Esebenzayo (WE): Kulapho kwenzeka khona impendulo ye-electrochemical enomdla. Iimpawu zezinto kunye nomphezulu wale electrode zibalulekile ekusebenzeni kwesensor.
* I-Electrode yeReference (RE): Ibonelela nge-reference potential ezinzileyo apho amandla e-electrode esebenzayo alinganiswa khona.
* I-Counter Electrode (i-CE okanye i-Auxiliary Electrode): Igqibezela isekethe yombane, ivumela ukuba umbane ugeleze phakathi kwee-electrode ezisebenzayo kunye nee-counter electrodes.
* I-Electrolyte: Isixhobo esilula ukuhamba kwee-ions kwaye sixhasa ukusabela kwe-electrochemical kwi-electrodes.

3. Amanyathelo Okusebenza:

* Ukuvezwa kwi-Analyte: Xa imolekyuli ekujoliswe kuyo (okanye i-analyte) ivezwa kwi-electrode esebenzayo, ifumana impendulo ye-electrochemical - nokuba iyanyibilika (ilahlekelwa zii-electron) okanye inciphe (ifumana ii-electron).
* Ukudluliselwa kwee-electron: Olu hlobo lokusabela kwee-electron lubandakanya ukudluliselwa kwee-electron phakathi kwe-analyte kunye ne-electrode, nto leyo edala isignali yombane enokulinganiswa.
* Ukulinganiswa kweSignali: Isignali yombane evelisiweyo (nokuba ngumahluko onokwenzeka okanye umbane) emva koko ilinganiswa ngokuchasene nereferensi ezinzileyo ebonelelwa yi-electrode yereferensi.
* Ingcaciso yeDatha: Ubungakanani bale signali yombane bunxulumene ngokuthe ngqo noxinzelelo lwe-analyte. Ngokuthelekisa isignali ne-calibration curve okanye ngokusebenzisa indlela eyaziwayo ye-analyte, uxinzelelo lwayo lunokufunyanwa.

4. Iintlobo zeeSensors zeElectrochemical:

* IiSensors zePotentiometric: Linganisa umahluko onokubakho phakathi kwee-electrodes ezisebenzayo kunye neereferensi. Iimitha ze-pH ziqhelekile.
* IiSensors ze-Amperometric: Linganisa umsinga ovela kwi-electrochemical reaction ye-analyte kwi-electrode esebenzayo. Iimitha zeglucose zihlala zisebenzisa iisensors ze-amperometric.
* IiSensors ze-Impedimetric: Linganisa utshintsho lwe-impedance okanye ukuxhathisa kwiseli ye-electrochemical xa usebenzisana nomhlalutyi.
* IiSensors zeConductometric: Linganisa utshintsho kwindlela esebenza ngayo isisombululo se-electrolyte xa usebenzisana ne-analyte.

5. Iingenelo zeeSensors zeElectrochemical:

* Uvakalelo oluphezulu kunye nokukhetha.
* Ixesha lokuphendula ngokukhawuleza.
* Ubuchule bokusebenza kwizigaba zolwelo kunye negesi.
* Ubuchule bokusebenza kwiisampuli ezimdaka okanye ezinemibala.
* Ihlala iphathwa kwaye ifanelekile kuhlalutyo lwangexesha langempela.

6. Imida:

* Izinzwa zinokungcoliswa okanye zityhefwe zizinto ezingcolisayo, nto leyo echaphazela ukusebenza kwazo.
* Ukutsiba kwi-reference electrode potential kunokukhokelela kwiimpazamo.
* Ezinye zifuna ukulinganiswa rhoqo ukuze kugcinwe ukuchaneka.

Ngokubanzi, ukusebenza kwee-sensors ze-electrochemical kuxhomekeke kuyilo oluthile, izixhobo ezisetyenzisiweyo, kunye nohlobo lwempendulo ye-electrochemical ye-analyte ekujoliswe kuyo. Uluhlu olubanzi lwezicelo zazo luqala ekujongeni okusingqongileyo kunye nokuxilongwa kwezonyango ukuya ekuqinisekiseni umgangatho wokutya nangaphezulu.
