Taw qhia rau Hom Sensor rau Hydrogen Sulfide Gas Detectors
Hydrogen sulfide detector yog ib qho cuab yeej tshawb nrhiav roj uas feem ntau tshawb pom cov roj concentration hauv ib puag ncig tam sim no los ntawm cov sensors thaum siv. Hydrogen sulfide detectors tuaj yeem siv ntau hom sensors kom pom cov roj hydrogen sulfide zoo dua hauv ib puag ncig. Hauv qab no, peb yuav qhia txog hom sensors siv hauv hydrogen sulfide detectors.
Hydrogen sulfide ntes sensor hom
1. Cov roj teeb tseem ceeb hom roj teeb: Nws txoj hauv kev ua haujlwm yog tib yam li cov roj teeb uas nquag siv, tshwj tsis yog cov roj hluav taws xob hloov cov roj carbon manganese electrode ntawm lub roj teeb, xws li oxygen sensor. Tom qab cov pa oxygen txo ntawm lub cathode, electrons ntws mus rau lub anode los ntawm ammeter, thiab cov hlau lead yog oxidized ntawm lub anode. Qhov loj ntawm qhov tam sim no muaj feem xyuam rau qhov concentration ntawm cov pa. Kev siv lub roj teeb thawj hom roj teeb tuaj yeem kuaj pom ntau yam roj.
2. Tsis tas li muaj peev xwm electrolytic cell type gas sensor: Nws plays lub luag haujlwm zoo heev hauv kev kuaj xyuas cov pa roj carbon monoxide, thiab nws lub hauv paus ntsiab lus txawv ntawm cov roj teeb thawj hom sensor. Nws undergoes electrochemical cov tshuaj tiv thaiv nyob rau hauv lub zog ntawm tam sim no. belongs rau qhov tseeb Coulomb tsom xam sensor. Hom sensor no tuaj yeem siv tsis tau tsuas yog siv los ntsuas cov pa roj carbon monoxide, tab sis tseem tuaj yeem tshawb xyuas ntau yam roj xws li carbon monoxide, hydrogen, ammonia, hydrazine, thiab lwm yam. Nws yog tam sim no lub ntsiab sensor rau kev kuaj cov pa phem thiab cov pa phem.
3. Concentration roj teeb hom roj sensor: Nws muaj electrochemical active gases tam sim no ntawm ob sab ntawm lub electrochemical roj teeb, uas yuav cia li tsim concentration electromotive quab yuam thaum lub sij hawm ua hauj lwm. Qhov loj ntawm lub zog electromotive muaj feem xyuam rau cov roj concentration. Hom sensor no tsuas yog siv nyob rau hauv oxygen sensors rau tsheb thiab khoom electrolyte hom carbon dioxide sensors.
4. Hom roj tam sim no siab heev: Nws yog ib qho sensor siv los ntsuas cov roj concentration. Cov pa roj concentration sensor yog npaj raws li lub hauv paus ntsiab lus hais tias cov huab tam sim no nyob rau hauv lub electrochemical pas dej ua ke muaj feem xyuam rau cov carrier concentration. Nws tuaj yeem siv rau kev tshawb nrhiav roj concentration hauv kev lag luam tsheb thiab kev tshawb nrhiav roj concentration hauv cov hlau molten.
