Kev faib tawm ntawm cov khoom siv hluav taws xob combustible thiab qhov tseem ceeb ntawm kev saib xyuas
Semiconductor Gas Detector
Ntawm qhov kub thiab txias, cov conductivity hloov nrog kev hloov pauv ntawm cov pa roj ambient. Piv txwv li, lub ntsuas dej cawv tau npaj raws li lub hauv paus ntsiab lus uas thaum tin dioxide ntsib cov pa cawv ntawm qhov kub siab, qhov kev tiv thaiv yuav txo qis.
Semiconductor gas sensors tuaj yeem siv tau zoo los kuaj xyuas ntau cov pa roj xws li methane, ethane, propane, butane, cawv, formaldehyde, carbon monoxide, carbon dioxide, ethylene, acetylene, vinyl chloride, styrene, acrylic acid, thiab lwm yam. ntawm sensor yog tus nqi qis thiab tsim nyog rau kev tshawb nrhiav cov pa hluav taws xob hauv pej xeem.
Catalytic combustion gas detector
Lub chemical combustion sensor muaj ob lub taag resistors tsim ib tug Wheatstone nrhiav kom tau choj. Thaum cov roj sib xyaw flammable diffuses mus rau qhov kev tshawb pom, nws sai dhau los ntawm cov nplaim taws uas tsis muaj hluav taws xob thiab ua rau cov tshuaj tiv thaiv tshav kub, uas ua rau muaj kev tiv thaiv ntawm cov hlau kub thiab tus choj tawm qhov hloov hluav taws xob teeb liab. Qhov loj ntawm qhov teeb liab voltage no muaj feem xyuam rau qhov tsis kam ntawm cov pa taws. proportional rau qhov concentration. Nws qhov zoo yog: kev xaiv zoo, cov lus teb raug, kev ruaj ntseg zoo, muaj peev xwm ntawm kev tshawb nrhiav kom muaj nuj nqis, tsis ua rau lub tswb tsis raug, kev tswj xyuas kom ntseeg tau, thiab lub neej ntev li peb xyoos. Nws yog qhov tsim nyog rau kev tshawb nrhiav cov pa roj carbon monoxide. Tam sim no, feem ntau combustible gas detection nyob rau hauv lub ntiaj teb no siv hom sensor.
Qhov tseem ceeb ntawm kev saib xyuas ntawm Cov Hluav Taws Xob Hluav Taws Xob
Vim tias qhov chaw ua haujlwm ntawm cov khoom siv hluav taws xob hluav taws xob yog qhov hnyav, lawv feem ntau yuav tsum tau muab tso rau sab nraum zoov. Sab nraum zoov, lawv feem ntau raug cua thiab lub hnub, thiab lawv nyob ib puag ncig los ntawm ntau yam pa phem, uas tseem yuav nkag mus rau hauv lub tshuab ntes, thiab qhov no tsis tuaj yeem zam tau. Peb tuaj yeem suav qhov xwm txheej no raws li lub hom phiaj ntawm kev puas tsuaj. Cov kev puas tsuaj no yuav muaj qee yam cuam tshuam rau peb cov ntaub ntawv. Txhawm rau kom siv nws cov txiaj ntsig zoo dua, peb yuav tsum tau them nyiaj tshwj xeeb rau kev saib xyuas thiab kev saib xyuas kom txo qis qhov cuam tshuam ntawm cov khoom siv hluav taws xob hluav taws xob, yog li ua kom paub tseeb qhov tseeb. Tus nqi raug ntawm cov ntaub ntawv, yog li nws yog ib qho tseem ceeb heev rau kev ntxuav thiab tswj cov khoom siv hluav taws xob hluav taws xob, uas yog ib qho tseem ceeb rau kev tiv thaiv.
Ntawm chav kawm, yog tias lub tshuab hluav taws xob hluav taws xob tsis tu ncua tsis tu ncua, nws tseem yuav ua rau nws txoj kev laus nrawm dua. Rau cov lag luam, cov nqi poob ntawm cov khoom siv lag luam kuj yog siab heev. Cov lag luam yuav tsum nco ntsoov tias lawv yuav tsum tsis txhob hnov qab hloov cov khoom siv tom qab lub sijhawm kom tsis txhob poob rau lub lag luam.
