Chii chinonzi Electrochemical Gasi Sensor

Sei Uchishandisa Electrochemical Gasi Sensor?

Iyo electrochemical sensor chimwe chezvinhu zvakakosha zveiyogasi sensor.Electrochemistry inonyanya kureva kushanda kwayo musimboti.

Inoshanda nekugadzira kemikari inopindirana negasi yakayerwa uye kugadzira chiratidzo chemagetsi chinoenzana nehuwandu hwegasi.

Mazhinji emagetsi emagetsi gasi sensors ari mu diffusion mode, uye magasi emuenzaniso mamorekuru ari munzvimbo yakatenderedza anoyerera nemumaburi madiki ari kumberi kwe sensor kuti apinde mu sensor.Mimwe michina ichave nepombi yemhepo yekukwevera mhepo uye gasi samples mu sensor, wozoitarisa.

Kuti udzivise pesvedzero, kuve nechokwadi chechokwadi chekutarisa, mumapores eHoi chikamu negasi-permeable membrane chipingamupinyi kune mhute yemvura, uye kumwe kusvibiswa mukati me sensor.Chiyero chekuyera uye kunzwisiswa kwe sensor kunogona kuchinjwa nekugadzirisa ukuru hwemhepo inopinza panguva yekugadzira.

Gomba guru remhepo rinogona kuvandudza kunzwisiswa uye kugadzirisa kwe sensor, nepo diki mhepo inopinza inoderedza kunzwisiswa uye kugadzirisa, asi inowedzera kuyerwa kwechiyero.

Edza Electrochemical Gasi Sensor neHENGKO Manufacture

Parizvino, electrochemical sensors yakashandiswa zvakanyanya mukuchengetedza chikafu, kuongororwa kwehupenyu, mushonga wehupenyu, kutarisa kwezvakatipoteredza, etc. Electrochemical sensors inogona kuona ozone, formaldehyde, carbon monoxide, ammonia, hydrogen sulfide, sulfur dioxide, nitrogen dioxide, okisijeni uye mamwe magasi. .HENGKO ine akasiyana emagetsi masensa, akadai seokisijeni sensors, hydrogen sulfide sensors, carbon monoxide sensors, ammonia sensors, carbon dioxide sensors, nezvimwe.

Mukuwedzera, kunekuputika-proof discs, gasi sensor kufema magomba,gasi sensor modules, gasi sensor probes, gasi detectorruzha uye chiedza aramu zvikamu, gasi transmitter modules, gasi sensor alarm accessories, nezvimwe kuzadzisa zvinodiwa nemaindasitiri akasiyana.

Iyo yakanakisa electrochemical sensor ndiyo sensor inoona oxygen.Mushure mezvose, yekutanga electrochemical sensor yakatanga kushandiswa kutarisisa okisijeni.Iine sarudzo yakanaka, kuvimbika uye kurarama kwenguva refu.Mamwe masensor eelectrochemical anogona kukanganisa kukanganiswa kubva kune mamwe magasi.Iyo data yekukanganisa inoverengerwa uchishandisa yakaderera gasi concentrations.

Mumashandisirwo anoshanda, kupindira kwekukanganisa kungave kwakanyanya, izvo zvinogona kukonzera kuverenga kwenhema kana maaramu enhema.Hengge kuputika-uchapupu yakakwirira-chaiyo inorwisa kupindira kwemaindasitiri okisijeni sensor, kuita kwakanaka, kugadzikana uye kwakavimbika kushanda, kugadzika kuisirwa uye kugadzirisa, kushanda kuri nyore, kwakasimba kurwisa-kupindira, huwandu: 0-30% VOL , kunyatsoita: ± 3% (FS ), dzokorora Kuita: ≤ 2% , kugadziriswa: 1% VOL , nguva yekupindura: ≤ 30 seconds, chiyero chekudzivirira chinogona kusvika IP65, IP66.

Electrochemical sensorsvane zvidikanwi zvakaderera zvesimba rekushanda, uye pakati pemarudzi ese emagetsi emagetsi, simba rayo rekushandisa ndiro rakaderera.Naizvozvo, sensor iyi inoshandiswa zvakanyanya munzvimbo shoma.Kazhinji kutaura, tarisiro yehupenyu ye electrochemical sensors ndeye 1-3 makore.Nekudaro, tarisiro yehupenyu ye sensor inonyanya kuenderana nekusvibiswa kwezvakatipoteredza, tembiricha uye humidity kwainofumurwa.Naizvozvo, kugaroonekwa uye kugadzirisa kwemagetsi sensors matanho anoshanda ekuwedzera hupenyu hwavo.

Unoziva Mashandisiro Anoita Electrochemical Sensor?

Pamibvunzo iyi, chekutanga tinofanira kuziva rumwe ruzivo rwekutanga senge musimboti, zvikamu, matanho ekushanda

unodawo kuziva mamwe marudzi anozivikanwa emagetsi emagetsi.zvino regai titarise mashoko sezvinotevera:

Electrochemical sensors anoshandiswa zvakanyanya kuona uye kuverengera akasiyana makemikari zvinhu nekushandisa misimboti ye electrochemistry.Heino mhedziso yakajairika yemashandiro avanoita:

1. Basic Principle:

Electrochemical sensors inoshanda nekuyera kugona kwemagetsi kana ikozvino inomuka nekuda kwekemikari inoitwa pane electrode pamusoro.

2. Basic Components:

* Kushanda Electrode (WE): Apa ndipo panoitika electrochemical reaction yekufarira.Izvo zvinhu uye pamusoro pezvivakwa zveiyi electrode zvakakosha pakuita sensor.
* Reference Electrode (RE): Inopa yakagadzikana yereferensi mukana weiyo iyo inoshanda ye electrode inoyerwa.
* Counter Electrode (CE kana Auxiliary Electrode): Inopedza kutenderera kwemagetsi, ichibvumira ikozvino kuyerera pakati pekushanda uye counter electrode.
* Electrolyte: Iyo svikiro inofambisa kufamba kwemaion uye inotsigira maitiro e electrochemical pama electrode.

3. Matanho Okushandisa:

* Kuratidzwa kune Analyte: Kana iyo inonangwa mamorekuru (kana analyte) inoratidzwa kune inoshanda electrode, inosangana ne electrochemical reaction - ingave iyo oxidized (inorasa maerekitironi) kana kuderedzwa (inowana maerekitironi).
* Electron Transfer: Iyi electrochemical reaction inosanganisira kutamiswa kwemaerekitironi pakati peanalyte neelectrode, kugadzira chiratidzo chemagetsi chinoyerika.
* Chiyero chechiratidzo: Chiratidzo chemagetsi chakagadzirwa (chingave mutsauko ungangoita kana chazvino) chinoyerwa nereferensi yakagadzikana inopihwa nereferenzi electrode.
* Dudziro Yedata: Hukuru hweiyi chiratidzo chemagetsi chakanangana nekusangana kweanalyte.Nekuenzanisa chiratidzo kune calibration curve kana kushandisa inozivikanwa maitiro eanalyte, kutarisisa kwayo kunogona kutsanangurwa.

4. Mhando dzeElectrochemical Sensors:

* Potentiometric Sensors: Edza mutsauko ungangoita pakati peanoshanda uye mareferenzi emagetsi.pH metres mienzaniso yakajairika.
* Amperometric Sensors: Edza iyo yazvino inokonzerwa ne electrochemical reaction yeanalyte pane inoshanda electrode.Glucose metres anowanzo shandisa amperometric sensors.
* Impedimetric Sensors: Edza iyo impedance kana kuramba shanduko mu electrochemical cell pakubatana neanalyte.
* Conductometric Sensors: Edza shanduko mukufambiswa kwemhinduro ye electrolyte pakusangana neanalyte.

5. Zvakanakira zveElectrochemical Sensors:

* High senitivity uye kusarudza.
* Inokurumidza kupindura nguva.
* Kugona kushanda mumvura uye gasi zvikamu.
* Kugona kushanda mune turbid kana mavara masampuli.
* Kazhinji inotakurika uye yakakodzera kuongororwa-nguva chaiyo.

6. Zvisingakwanisi:

* Masensor anogona kusvibiswa kana kucherwa nezvinosvibisa, zvichikanganisa kuita kwavo.
* Drift mune referensi electrode inogona kutungamira kune zvikanganiso.
* Zvimwe zvinoda kugadziriswa nguva nenguva kuti zvirambe zvakarurama.

Pakazere, kushanda kwe electrochemical sensors kunoenderana nedhizaini chaiyo, zvinhu zvinoshandiswa, uye chimiro che electrochemical reaction yeanonangidzira analyte.Kuwanda kwavo kwakasiyana-siyana kwekushandisa kunobva pakutarisa kwezvakatipoteredza uye kuongororwa kwezvokurapa kusvika kuhutano hwekudya uye mberi.
