Kev sib piv ntawm peb hom gasdetectors
1, Kev txheeb xyuas cov yam ntxwv ntawm Semiconductor Sensors
Lub semiconductor sensor gas detector yog tsim los ntawm kev hloov pauv hauv kev ua haujlwm. Tin dioxide sai txo nws txoj kev tiv thaiv thaum ntsib cov pa roj cawv ntawm qhov kub thiab txias, thiab lub ntsuas dej cawv tau npaj siv 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, 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 cov chaw uas muaj qhov ntsuas qhov tseeb.
2, Kev txheeb xyuas cov yam ntxwv ntawm combustion Sensors
Ib hom combustion sensor yog txheej txheej catalyst uas tiv taus qhov kub thiab txias 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 cov kuj. Kev tshawb nrhiav ntau yam ntawm catalytic combustion sensor gas detector tsuas yog suav nrog cov roj combustible. Yog tias cov roj tsis tuaj yeem hlawv, lub sensor yuav tsis tsim cov tshuaj tiv thaiv. Lub catalytic combustion gas detector teb kom raug, sai, thiab siv sijhawm ntev.
3, Kev soj ntsuam ntawm hom Electrochemical Sensors
Ib feem ntawm nws cov nplaim hluav taws kub, cov pa phem thiab cov pa phem muaj cov khoom siv hluav taws xob thiab tuaj yeem ua rau electrochemically oxidized los yog txo. Lub hauv paus ntsiab lus ntawm lub roj teeb thawj hom roj teeb 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 type gas sensors. Concentration roj teeb hom roj sensors tuaj yeem tsim kom muaj kev sib haum xeeb nyob ntawm electromotive quab yuam thiab ntes roj concentration, xws li oxygen sensors siv hauv tsheb.
