Kev Sib Tw ntawm Nitrogen oxide sensor
Ib puag ncig hnyav
Vim yog qhov kub ntawm qhov chaw combustion, tsuas yog qee yam ntawm cov khoom tuaj yeem ua haujlwm hauv situCov. Feem coob ntawm TSIS MUAJx sensors tsim tau los ntawm ceramic hom hlau oxides, nrog rau feem ntau yog ytria- ruaj khov zirconia (YSZ), uas yog tam sim no siv nyob rau hauv lub xyoo caum-laus oxygen sensor. YSZ yog compacted rau hauv ib tug ntom ceramic thiab ua cov pa oxygen ions (O2 ib) ntawm qhov kub siab ntawm lub tailpipe xws li ntawm 400 ° C thiab siab dua. Kom tau txais lub teeb liab los ntawm lub sensor ib khub ntawm high-temperature electrodes xws li noble hlau (platinum, kub, los yog palladium) los yog lwm yam hlau oxides muab tso rau saum npoo thiab hluav taws xob teeb liab xws li qhov kev hloov ntawm qhov hluav taws xob los yog tam sim no yog ntsuas raws li kev ua haujlwm ntawm TSIS MUAJx mloog zoo.
High rhiab heev thiab durability yuav tsum tau
Cov qib NO yog nyob ib ncig ntawm 100-2000 ppm (qhov chaw ib lab) thiab NO2 20-200 ppm ntawm 1-10% O2. Lub sensor yuav tsum tau rhiab heev los khaws cov qib no.
Cov teeb meem tseem ceeb hauv kev txhim kho sensor yog kev xaiv, rhiab heev, ruaj khov, rov tsim dua tshiab, lub sijhawm teb, txwv tsis pub kuaj pom, thiab tus nqi. Tsis tas li ntawd vim qhov hnyav ntawm kev sib xyaw ua ke cov roj ntws siab tuaj yeem txias lub sensor uas hloov cov teeb liab lossis nws tuaj yeem delaminate cov electrodes dhau sijhawm thiab soot particles tuaj yeem degrade cov ntaub ntawv.
Ib qho ntawm cov teeb meem loj uas tau ntsib los ntawm cov pa roj carbon monoxide yog cov av noo. Qhov txheeb ze cuam tshuam rau cov teeb liab teb yog qhov ua tau zoo rau hom sensor. Electrochemical sensors feem ntau tiv thaiv los ntawm cov av noo vim cov dej molecules pab tswj cov electrolyte concentration tab sis ntev ntev raug rau cov roj qhuav tuaj yeem txo qhov hnyav ntawm cov electrolyte. Qhov siab ntawm tus ntoo khaub lig rhiab heev tau pom nyob rau hauv cov pa sensors vim qhov zoo sib xws hauv electron exchange mechanism ntawm lub hom phiaj gases thiab dej molecules.
