Dab tsi yog qhov sib txawv tseem ceeb ntawm cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv tshuaj lom neeg?
Lub combustible gas detector yog ib tug detector uas teb rau cov concentration ntawm ib los yog ntau combustible gases. Muaj ob hom kev ntsuas roj hluav taws xob: hom catalytic thiab infrared optical hom. Thaum cov roj combustible nkag mus rau hauv lub ntes, nws ua rau oxidation cov tshuaj tiv thaiv (flameless combustion) nyob rau saum npoo ntawm platinum hlau, thiab lub tshav kub generated tsub kom qhov kub ntawm lub platinum hlau, ua rau ib tug hloov nyob rau hauv nws cov hluav taws xob resistivity.
Cov cuab yeej siv tshuaj lom neeg tuaj yeem siv los txheeb xyuas qhov concentration ntawm cov pa phem hauv cov roj av, tshuaj lom neeg, thiab tshuaj kev lag luam hauv lub sijhawm tiag tiag los xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm! Lub tshuab kuaj xyuas roj toxic yog ib qho kev cuam tshuam dawb "ntse" detector tsim, uas tuaj yeem kuaj xyuas cov pa roj carbon monoxide thiab qhov dav ntawm nws qhov kev tshawb nrhiav ntau yam, uas yog qhov thib ob hauv kev lag luam.
Cov khoom siv hluav taws xob hluav taws xob thiab cov khoom siv tshuaj lom neeg yog cov cuab yeej siv hauv kev lag luam, thiab ntau tus neeg tsis paub txog qhov sib txawv ntawm ob. Kab lus hauv qab no yuav piav qhia rau koj:
1. Kev kuaj pom roj
Lub combustible gas detector feem ntau pom cov roj combustible, thiab siv methane raws li tus qauv los xyuas qhov concentration ntawm combustible gases. Raws li qhov sib txawv combustible gases nyob rau hauv tus neeg siv qhov chaw, qhov concentration ntawm cov roj tseem ceeb yuav siv tau raws li tus qauv nrhiav kom tau roj teeb.
Lub tshuab kuaj xyuas roj toxic yuav tsum paub seb cov pa roj tshwj xeeb lossis cov pa phem los kuaj xyuas. Nws tuaj yeem xaiv lub tswb ntsuas tshuaj lom neeg sib cais lossis cov khoom siv tshuaj lom neeg sib xyaw, nyob ntawm seb cov pa tshuaj lom hauv qhov chaw siv yuav tsum tau kuaj pom tias yog ib qho roj lossis ntau cov roj.
2. Gas sensor
Lub combustible gas detector siv catalytic combustion gas sensors, thaum lub toxic gas detector siv electrochemical sensors, infrared sensors, PID sensors, thiab lwm yam. Lub chav tsev concentration ntawm cov kuaj pom roj yog txawv, thiab ib tug series ntawm cov qauv yuav tsum tau hloov dua siab tshiab.
