Standardized Comparison ntawm Peb Hom Gas Detector
Lub semiconductor sensor gas detector yog tsim los ntawm kev hloov pauv hauv kev ua haujlwm. Tin dioxide ntsib qhov txo qis hauv kev tiv thaiv sai thaum raug cov pa roj cawv ntawm qhov kub thiab txias, thiab lub ntsuas dej cawv tau tsim los ntawm txoj cai no. Hom sensor no muaj cov yam ntxwv ntawm tus nqi qis thiab yog qhov tsim nyog rau kev kuaj xyuas cov pa phem hauv pej xeem. Ib puag ncig yam muaj feem cuam tshuam rau cov khoom siv hluav taws xob semiconductor sensor gas detectors, ua rau cov txiaj ntsig tsis ruaj khov. Thiab qhov tso zis tsis tau ntawm lub ntsuas roj no tsis tuaj yeem txiav txim siab, ua rau nws tsis tsim nyog rau qhov chaw uas yuav tsum tau ntsuas qhov tseeb.
2, Cov yam ntxwv tsom xam ntawm combustion Sensors
Lub combustion sensor yog siab - kub resistant catalyst txheej npaj rau saum npoo ntawm platinum resistor. Thaum qhov kub thiab txias txaus, combustible gases yuav undergo catalytic combustion, uas tsub kom lub kub ntawm lub platinum resistor thiab qhia txog cov concentration ntawm combustible gases los ntawm lub resistor. Kev tshawb nrhiav ntau yam ntawm cov catalytic combustion sensor gas detector tsuas yog suav nrog cov pa roj carbon monoxide, thiab yog tias cov roj tsis tuaj yeem hlawv, lub sensor yuav tsis tsim cov tshuaj tiv thaiv. Catalytic combustion gas detector muaj qhov tseeb, nrawm thiab ntev - cov tshuaj tiv thaiv ntev.
3, Kev soj ntsuam ntawm hom Electrochemical Sensors
Ib feem tseem ceeb ntawm nws cov nplaim taws, muaj kuab lom, thiab cov pa phem muaj cov khoom siv hluav taws xob thiab tuaj yeem ua rau electrochemically oxidized lossis txo. Lub hauv paus ntsiab lus ntawm thawj lub roj teeb hom roj sensor yog roughly tib yam li cov roj teeb qhuav. Kev tshawb pom tam sim no ntawm cov pa phem thiab cov pa phem feem ntau yog nyob ntawm qhov muaj peev xwm electrolytic cell gas sensors tas li. Lub roj teeb concentration hom roj sensor tuaj yeem tsim kom muaj qhov sib txawv ntawm lub zog electromotive thiab ntes cov roj concentration, xws li oxygen sensor siv hauv tsheb.
