Oxygen sensors yog ib qho tseem ceeb ntawm cov tshuab tsheb niaj hnub. Cov sensors no tau tsim los ntsuas cov pa oxygen hauv cov pa tawm thiab muab cov ntaub ntawv tseem ceeb rau lub cav tswj qhov system. Muaj peb hom oxygen sensors feem ntau siv nyob rau hauv combustion engines: zirconia sensors, titanium dioxide sensors, thiab broadband sensors.
Zirconia sensors yog hom kev siv ntau tshaj plaws ntawm oxygen sensor. Nws txoj haujlwm ua haujlwm yog siv ceramic oxides ua los ntawm zirconia. Qhov ntsuas no siv qhov sib txawv ntawm qhov sib txawv ntawm ob lub electrodes los ntsuas cov pa oxygen hauv cov pa tawm. Hom sensor no yog dav siv nyob rau hauv ntau lub tsheb thiab yog heev txhim khu kev qha.
Titanium dioxide sensor yog ib qho oxygen sensor uas siv titanium dioxide ua lub ntsiab lus. Tsis zoo li zirconia sensors, hom sensor no siv cov kev hloov pauv hauv sensor tsis kam ntsuas oxygen concentration. Hom sensor no yog siv rau hauv cov ntawv thov uas lub cav tswj qhov system yuav tsum ua haujlwm nyob rau hauv qhov kub thiab txias.
Broadband sensors yog hom tshiab ntawm oxygen sensors ntawm lub khw. Nws siv cov txheej txheem sensor txheej txheej txheej nrog cov khoom muaj tswv yim uas tuaj yeem hnov mob rau cov pa oxygen hauv cov pa tawm. Piv nrog rau lwm yam ob hom sensors, hom sensor no tuaj yeem ntsuas cov pa oxygen ntau dua. Qhov ntsuas no muab qhov ntsuas dav dua thiab tuaj yeem kuaj pom ntau dua ntawm cov concentration lossis dilution.
Zuag qhia tag nrho, oxygen sensors ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub cav los ntawm kev muab cov ntaub ntawv rau lub cav tswj qhov system. Txawm hais tias muaj peb hom sensors, txhua tus nrog nws qhov tshwj xeeb zoo, cov sensors no yog txhua tus tsom rau kev txhim kho lub cav, kev ua haujlwm, thiab kev ntseeg siab. Yog li, tom ntej no koj pom lub cav kuaj lub teeb los ntawm, thov nco ntsoov tias lub ntsuas pa tsis zoo yuav yog qhov teeb meem, tsis yog qhov teeb meem me me xwb!
