Classification standard rau gas detectors
Gas Detector yog ib qho cuab yeej siv los ntsuas cov pa tawm ntawm cov pa tawm.
Gas detectors feem ntau yog siv roj sensors los xyuas cov hom gases tam sim no nyob rau hauv ib puag ncig, thiab roj sensors yog sensors siv los xyuas cov muaj pes tsawg leeg thiab cov ntsiab lus ntawm gases. Nws yog feem ntau ntseeg hais tias lub ntsiab lus ntawm cov pa sensors
Nws yog raws li kev faib tawm ntawm cov hom phiaj nrhiav pom, uas txhais tau hais tias txhua lub sensor siv los ntsuas cov roj muaj pes tsawg leeg thiab cov concentration yog hu ua gas sensor, tsis hais seb nws puas siv lub cev lossis tshuaj.
Muaj ntau cov qauv kev faib tawm rau cov khoom siv roj
1. Gas detectors raug cais los ntawm cov khoom tshawb nrhiav, suav nrog cov roj hluav taws xob (xws li methane) lub tswb ntsuas, lub tswb ntsuas roj toxic, thiab lub tswb ntsuas oxygen.
2. Raws li kev faib tawm ntawm cov qauv kev tshawb nrhiav, kev tshawb nrhiav cov roj combustible muaj xws li hom catalytic combustion, semi conductive type, thermal conductivity type, thiab infrared absorption type; Kev kuaj pom muaj pa phem xws li electrochemical thiab semiconductor hom; Oxygen detection
Muaj hom electrochemical, thiab lwm yam.
3. Muab faib los ntawm kev siv, muaj cov khoom txav tau yooj yim thiab ruaj khov.
4. Muab faib los ntawm qhov chaw siv, muaj cov pa thiab tawg-pov thawj hom.
5. Raws li kev ua haujlwm ntawm kev faib tawm, muaj cov khoom siv roj, lub tswb nrov, thiab lub tswb ntsuas roj.
6. Muab faib los ntawm txoj kev sampling, muaj hom diffusion thiab twj tso kua mis hom
