Icyuma gikoresha amashanyarazi ni iki?

Sensor ya gaz ya mashanyarazi

Kuki Ukoresha Amashanyarazi ya Gaz?

Amashanyarazi yumuriro nimwe mubintu byingenzi bigizeicyuma cya gaze. Amashanyarazi yerekeza cyane cyane ku ihame ryayo.

Ikora itanga reaction ya chimique hamwe na gaze yapimwe kandi itanga ibimenyetso byamashanyarazi bihwanye na gaze.

Ibyuma byinshi byifashishwa mu mashanyarazi biri mu buryo bwo gukwirakwiza, kandi molekile ya gaze ya gaze mu bidukikije ikunze gutembera mu mwobo muto uri imbere ya sensor kugirango yinjire muri sensor. Ibikoresho bimwe bizaba bifite pompe yo mu kirere ikurura ibyuka bya gaze na gaze muri sensor, hanyuma ikabikurikirana.

Kugira ngo wirinde ingaruka, kugirango hamenyekane neza niba igenzura ryakozwe neza, mu byobo by'igice cya Hoi hamwe na gazi ishobora kwinjizwa na membrane inzitizi ku myuka y'amazi, hamwe n'indi myanda iri muri sensor. Ikigereranyo cyo gupima hamwe na sensitivite ya sensor irashobora guhinduka muguhindura ingano yumuyaga winjira mugihe cyo gushushanya.

Umwobo munini wo mu kirere urashobora kunoza ibyiyumvo no gukemura bya sensor, mugihe umwuka muto wo mu kirere ugabanya ibyiyumvo no gukemura, ariko byongera urugero rwo gupima.

Gerageza Amashanyarazi ya Sensor ya HENGKO

Kugeza ubu, ibyuma bikoresha amashanyarazi byakoreshejwe cyane mu kwihaza mu biribwa, gusesengura ibinyabuzima, ubuvuzi bw’ubuzima, gukurikirana ibidukikije, n’ibindi. . HENGKO ifite ibyuma bitandukanye bikoresha amashanyarazi, nka sensor ya ogisijeni, ibyuma bya hydrogène sulfide, ibyuma bya karuboni monoxide, ibyuma bya amoniya, ibyuma bya dioxyde de carbone, n'ibindi.

Byongeye, harihodisiki idashobora guturika, sensor ya gaze ihumeka ibishishwa,gazi ya sensor modules, gaze ya sensor, icyuma gipima gazeibice byerekana amajwi n'amatara, moderi yohereza gazi, ibikoresho bya sensor sensor ya gazi, nibindi kugirango bikemure inganda zitandukanye.

Icyuma cyiza cya electrochemiki nicyuma cyerekana ogisijeni. Nyuma ya byose, sensor ya electrochemic ya mbere yakoreshejwe bwa mbere mugukurikirana ogisijeni. Ifite guhitamo neza, kwiringirwa no kuramba. Ibindi byuma byamashanyarazi birashobora kwangizwa nizindi myuka. Imibare yivanga ibarwa ikoresheje ingufu nke za gaze.

Mubikorwa bifatika, intumbero yibanze irashobora kuba ndende cyane, ishobora gutera gusoma nabi cyangwa gutabaza. Hengge iturika-idasobanutse neza-irwanya-kwangiriza inganda za ogisijeni yinganda, imikorere myiza, imikorere ihamye kandi yizewe, gushiraho no kubungabunga neza, gukora byoroshye, kurwanya-kwivanga, intera: 0-30% VOL, ukuri: ± 3% (FS ), subiramo Imikorere: ≤ 2%, gukemura: 1% VOL, igihe cyo gusubiza: seconds amasegonda 30, urwego rwo kurinda rushobora kugera kuri IP65, IP66.

Amashanyarazizifite ibisabwa bike cyane kububasha bwo gukora, kandi mubwoko bwose bwa sensororo ya gaze, gukoresha ingufu ni bike. Kubwibyo, iyi sensor ikoreshwa cyane mumwanya muto. Muri rusange, icyizere cyo kubaho kwa sensor ya electrochemic ni imyaka 1-3. Nyamara, igihe cyo kubaho cya sensor ahanini giterwa n’umwanda w’ibidukikije, ubushyuhe n’ubushuhe bugaragaramo. Kubwibyo, gutahura no gufata neza ibyuma bifata amashanyarazi ningamba zifatika zo kongera ubuzima bwabo.

Waba uzi uko Sensor ya Electrochemical ikora?

Kuri ibi bibazo, ubanza tugomba kumenya amakuru yibanze nkihame, ibice, intambwe yimikorere

ukeneye kandi kumenya ubwoko bumwebumwe buzwi bwa sensororo ya electrochemic. noneho reka turebe amakuru arambuye:

Ibyuma bifata amashanyarazi bikoreshwa cyane mugushakisha no kugereranya ibintu bitandukanye bya shimi ukoresheje amahame ya electrochemie. Dore muri rusange uko bakora:

1. Ihame shingiro:

Ibyuma bifata amashanyarazi bikora bipima ubushobozi bwamashanyarazi cyangwa amashanyarazi avuka bitewe nubushakashatsi bwimiti hejuru ya electrode.

2. Ibice by'ibanze:

* Electrode ikora (WE): Aha niho reaction ya electrochemic reaction yinyungu. Ibikoresho nubuso biranga iyi electrode nibyingenzi mubikorwa bya sensor.
* Reba Electrode (RE): Itanga ubushobozi buhamye bwo gupima ubushobozi bwa electrode ikora.
* Counter Electrode (CE cyangwa Auxiliary Electrode): Yuzuza uruziga rw'amashanyarazi, ituma umuyoboro utemba hagati ya electrode ikora na compte.
* Electrolyte: Igikoresho cyoroshya kugenda kwa ion kandi kigashyigikira reaction ya electrochemic reaction kuri electrode.

3. Intambwe zo Gukora:

* Guhura na Analyte: Iyo molekile yintego (cyangwa analyte) ihuye na electrode ikora, ihura na electrochemic reaction - yaba oxyde (itakaza electron) cyangwa igabanuka (yunguka electron).
* Ihererekanyabubasha rya elegitoronike: Iyi reaction ya electrochemicique ikubiyemo ihererekanyabubasha rya electron hagati ya analyte na electrode, bigakora ibimenyetso byamashanyarazi bipimwa.
* Ibipimo by'ibimenyetso: Ikimenyetso cy'amashanyarazi cyakozwe (haba itandukaniro rishobora kuba cyangwa ikigezweho) noneho gipimirwa ku gihagararo gihamye gitangwa na electrode yerekana.
* Ibisobanuro byamakuru: Ubunini bwiki kimenyetso cyamashanyarazi bufitanye isano itaziguye na concentration ya analyte. Mugereranije ibimenyetso na kalibibasi cyangwa gukoresha imyitwarire izwi ya analyte, kwibanda kwayo birashobora kugenwa.

4. Ubwoko bwa Electrochemical Sensors:

* Potentiometric Sensors: Gupima itandukaniro rishobora kuba hagati yakazi na electrode yerekana. metero metero ni ingero zisanzwe.
* Amperometric Sensors: Gupima ikigezweho gituruka kumashanyarazi ya reaction ya analyte kuri electrode ikora. Metero ya glucose ikunze gukoresha amperometrike.
* Sensors Impedimetric: Gupima impedance cyangwa irwanya impinduka mumashanyarazi ya selile nyuma yo gukorana na analyte.
* Sensors ya Conductometric: Gupima impinduka mumikorere yumuti wa electrolyte nyuma yo gukorana na analyte.

5. Ibyiza bya Sensor ya Electrochemiki:

* Kwiyunvikana cyane no guhitamo.
* Igihe cyo gusubiza vuba.
* Ubushobozi bwo gukora mubice byamazi na gaze.
* Ubushobozi bwo gukora mubyitegererezo cyangwa amabara.
* Akenshi birashoboka kandi bikwiranye nisesengura ryigihe.

6. Imipaka:

* Sensors irashobora kwanduzwa cyangwa uburozi bwanduye, bigira ingaruka kumikorere yabo.
* Gutwara muri electrode yerekana bishobora kuganisha ku makosa.
* Bamwe bakeneye kalibrasi yigihe kugirango bakomeze neza.

Muri rusange, imikorere ya sensororo yamashanyarazi biterwa nigishushanyo cyihariye, ibikoresho byakoreshejwe, hamwe nimiterere ya electrochemic reaction ya analyte yintego. Ubwoko bwabo bwinshi bwibikorwa biva mugukurikirana ibidukikije no gupima ubuvuzi kugeza ubwiza bwibiryo ndetse nibindi.
