Gas detector yog ib qho transducer uas hloov cov ntim feem ntawm cov roj mus rau hauv cov teeb liab hluav taws xob. Xav paub cov roj sensor ntes, koj yuav tsum kawm txog lub ntsiab lus ntawm cov kev txwv thaum xub thawj.
Teb sijhawm
Nws yog hais txog lub sij hawm los ntawm lub detector tiv tauj cov roj ntsuas kom ncav cuag tus nqi ruaj khov nyob rau hauv qee yam kev sim. Feem ntau, nws yog lub sij hawm teb thaum nyeem tus nqi ruaj khov yog 90%, uas yog T90. Cov txheej txheem ntawm cov pa samplingmuaj a zoo heev cawvntawm lub sijhawm teb ntawm lub sensor. Txoj kev ua piv txwv feem ntau yog qhov yooj yim diffusion lossis rub cov pa rau hauv lub ntsuas. Ib qho txiaj ntsig ntawm diffusion yog qhia cov qauv roj ncaj qha rau hauv lub sensor yam tsis muaj kev hloov pauv ntawm lub cev thiab tshuaj lom neeg. Txoj kev ntsuas ntawm HENGKO taag gas detector yog diffusion.
Skev ruaj ntseg
Hais txog kev ruaj ntseg ntawm cov lus teb yooj yim ntawm lub sensor thaum lub sijhawm ua haujlwm tag nrho. Nws nyob ntawm xoom drift thiab Interval drift. Zero drift yog hu ua kev hloov pauv hauv cov lus teb cov lus teb rau lub sijhawm ua haujlwm tag nrho thaum tsis muaj lub hom phiaj roj. Lub caij nyoog drift yog xa mus rau qhov tso zis teb hloov pauv ntawm lub sensor txuas ntxiv tso rau hauv lub hom phiaj roj, uas yog tshwm sim raws li qhov txo qis ntawm cov teeb liab tawm ntawm lub sijhawm ua haujlwm.
Hais txog qhov sib piv ntawm qhov ntsuas qhov tso zis hloov pauv mus rau qhov ntsuas kev hloov pauv hloov pauv.Cov qauv tsim yog Biochemistry, Electrochemistry,physicsthiab Optics rau ntau cov pa sensors.
Kev xaiv
Nws kuj hu ua Cross rhiab heev. Nws tuaj yeem txiav txim siab los ntawm kev ntsuas cov lus teb sensor tsim los ntawm qee qhov concentration ntawm cov pa cuam tshuam. Cov yam ntxwv no tseem ceeb heev hauv kev taug qab ntau daim ntawv thov roj, vim tias qhov kev sib tw hla yuav txo qhov rov ua dua thiab kev ntseeg siab ntawm kev ntsuas.
Hais txog lub peev xwm ntawm lub sensor kom raug rau ib tug siab ntim feem ntawm lub hom phiaj roj. Thaum muaj cov pa paug ntau, qhov kev sojntsuam yuav tsum tuaj yeem tiv taus 10-20 npaug ntawm qhov xav tau roj ntim feem. Muajib me muaj peev xwmrau sensor drift thiab xoom kho thaum nws rov qab los ua haujlwm zoo. Qhov kev tiv thaiv corrosion ntawm qhov kev sojntsuam yog qhov tseem ceeb heev vim tias ntau zaus peb pom cov pa xau hauv ib puag ncig tsis zoo. HENGKO stainless hlau lim vaj tsev muaj qhov zoo ntawm qhov tawg, nplaim hluav taws thiab tawg-pov thawj, tsim nyog rau qhov hnyav hnyav heev. Dustproof, anti-corrosion, IP65 qib waterproof, tuaj yeem tiv thaiv cov roj sensor module los ntawm plua plav tau zoo dua. Cov pa phem ntawm micro-particles thiab oxidative los ntawm cov tshuaj lom neeg feem ntau txo qhov zaus ntawm sensor lom, xyuas kom meej tias nws tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev, muaj kev ntseeg siab dua thiab ua kom lub neej zoo, thiab nyob ze rau lub neej theoretical ntawm lub sensor.
Gas sensor feem ntau tuaj yeem xaiv los ntawm cov pa rhiab heev. Nws yog tsuas yog muab faib ua Semiconductor gas sensor, Electrochemical gas sensor, Photochemical gas sensor, Polymer gas sensor thiab thiaj li on.HENGKO gas sensor feem ntau yog Electrochemical gas sensor thiab Catalytic combustion gas sensor.
Lub tshuab hluav taws xob hluav taws xob hluav taws xob yog lub ntsuas hluav taws xob uas oxidizes lossis txo cov roj los ntsuas ntawm cov electrode los ntsuas qhov tam sim no thiab tau txais qhov concentration ntawm cov pa. Cov roj diffuses mus rau hauv kev ua hauj lwm electrode ntawm lub sensor los ntawm sab nraum qab ntawm lub porous membrane, qhov twg cov roj yog oxidized los yog txo, thiab cov tshuaj electrochemical no ua rau ib tug tam sim no ntws los ntawm lub sab nraud Circuit Court. HENGKO co gas sensor yog Electrochemical gas sensor.
Catalytic combustion gas sensor
Catalytic combustion gas sensor yog ua raws li lub hauv paus ntsiab lus thermal nyhuv ntawm catalytic combustion. Cov khoom kuaj pom thiab cov nyiaj them poob haujlwm yog khub los ua tus choj ntsuas. Nyob rau hauv tej yam kev mob kub, combustible gas yuav undergone flameless combustion nyob rau saum npoo ntawm lub detection ntsiab cab kuj thiab cov catalyst. Cov cab kuj kub Nws nce, thiab cov platinum hlau tsis kam nyob rau hauv nws nce raws li, kom tus choj tshuav nyiaj li cas yog tsis tshuav, thiab ib tug hluav taws xob teeb liab proportional rau lub concentration ntawm combustible gas yog tso zis. Los ntawm kev ntsuas qhov kev hloov pauv ntawm cov hlau platinum, qhov concentration ntawm cov pa taws tuaj yeem paub tau. Feem ntau yog siv rau kev tshawb pom ntawm cov pa roj carbon monoxide. Nws tsuas yog siv rau kev tshawb nrhiav cov pa roj carbon monoxide.Piv txwv li, Hengge combustible gas sensor, Hengge hydrogen sulfide sensor, thiab lwm yam. yog cov thermal nyhuv ntawm catalytic combustion.
HENGKO muaj 10 xyoo OEM / ODM cutomized experiance, 10 xyoo kev sib koom tes tsim / pab tsim muaj peev xwm.Our cov khoom muag zoo nyob rau hauv ntau precision muaj lub teb chaws nyob rau hauv lub ntiaj teb no. Muaj ntau tshaj 100,000 qhov ntau thiab tsawg thiab hom khoom xaiv los ntawm, thiab peb tuaj yeem kho thiab ua ntau yam khoom lim nrog cov qauv nyuaj raws li kev xav tau.
