Classification ntawm sensors rau gas detectors
Gas sensors yog ib pawg loj ntawm cov tshuaj sensors. Los ntawm lub hauv paus ntsiab lus ntawm kev ua hauj lwm, cov yam ntxwv tsom xam mus rau kev ntsuas technology, los ntawm cov ntaub ntawv siv rau cov txheej txheem tsim, los ntawm cov khoom tshawb nrhiav mus rau daim ntawv thov teb, lawv tuaj yeem tsim cov qauv kev faib tawm ywj siab, thiab muab tau ntau yam kev faib tawm, tshwj xeeb tshaj yog nyob rau hauv qhov teeb meem ntawm kev faib tawm. qauv. Tseem tsis tau muaj kev sib koom ua ke, nws yog qhov nyuaj heev los ua kom muaj kev sib cais nruj heev.
1. Muab faib raws li qhov xwm txheej ntawm cov roj yuav tsum tau kuaj
Raws li cov kev coj ntawm cov roj kom pom, nws tuaj yeem faib ua: sensors rau cov roj av, roj carbon monoxide, pa roj caratile, thiab lwm yam; sensors rau kev soj ntsuam cov pa phem, xws li chlorine, hydrogen sulfide, arsine, thiab lwm yam.;
2. Muab faib los ntawm daim ntawv thov teb
Raws li daim ntawv thov daim teb, nws tuaj yeem muab faib ua: sensors rau kev kuaj xyuas cov txheej txheem kev lag luam, xws li cov pa oxygen hauv steelmaking furnaces thiab carbon dioxide nyob rau hauv qhov cub kho cua sov; sensors rau kev soj ntsuam huab cua muaj kuab paug, xws li NOx, CH4, O3 uas tsim kua qaub nag; Sensors uas ntes cov pa phem hauv tsev xws li formaldehyde, thiab lwm yam.
3. Raws li cov qauv ntawm cov roj sensor
Raws li cov qauv ntawm cov roj sensor, nws tuaj yeem muab faib ua ob hom: hom qhuav thiab ntub hom.
4. Raws li cov zis ntawm lub sensor
Raws li cov zis ntawm lub sensor, nws tuaj yeem muab faib ua ob hom: resistive thiab non-resistive.
5. Muab faib los ntawm txoj kev tshawb nrhiav
Raws li txoj cai tshawb nrhiav, nws tuaj yeem muab faib ua: electrochemical method, hluav taws xob txoj kev, optical method thiab chemical method.
Kev tshawb fawb ntawm cov roj sensors muaj ntau qhov chaw thiab nyuaj, thiab yog cov ntsiab lus tshawb fawb ntau yam. Txhua tus neeg muaj kev nkag siab meej txog lub tswv yim, cov yam ntxwv thiab cov qauv kev faib tawm ntawm cov roj sensors. Tsuas yog los ntawm kev nkag siab tag nrho cov cuab yeej siv tau cov cuab yeej siv tau zoo dua rau kuv thiab ua kom nws muaj nuj nqis.
