Nws txhais li cas thaum tus pas ntsuas kub infrared qhia lo?
Tus pas ntsuas kub infrared muaj qhov kub thiab txias ntawm -50 degree rau 550 degree. Thaum lo pom, nws txhais tau tias kev tshawb nrhiav qhov kub yog qis dua qhov kev txwv qis, uas txhais tau tias qhov khoom koj ntsuas tau muaj qhov kub tsawg dua {2}} degree! Nws kuj yuav yog vim muaj roj teeb tsawg.
Kev Ntsuam Xyuas Qhov Ntsuas Ntsuas Tus Phov
Vim yog qhov tsis muaj kev sib cuag ntawm infrared thermometers, lawv ntsuas tau los ntawm ntau yam. Los ntawm qhov kev pom ntawm cov twj paj nruag ntawm cov ntsuas nws tus kheej, muaj ntau qhov: siv cov tsis yog qhov chaw ntsuas hluav taws xob, ntsuas hluav taws xob lossis hnav cov iav ci ntsa iab thiab cov cuab yeej siv hluav taws xob, thiab lwm yam; Los ntawm qhov kev pom ntawm sab nraud yam, ntsuas tau cuam tshuam los ntawm cov khoom siv tau ntsuas, ntsuas ntsuas nrug deb, thiab ntsuas kub ntawm sab nraud ib puag ncig.
Kev daws rau qhov yuam kev ntawm infrared thermometers
Hauv cov ntawv thov, rau ntawm thaj chaw sib piv thiab ntsuas hluav taws xob feem ntau siv los txo cov teebmeem no. Nyob ntawm seb qhov ntsuas kub tiag tiag xav tau, ntau txoj kev ntsuas kub tau xaiv raws li, thiab kev ntsuas hluav taws xob yog los ntawm qhov kub tsawg rau qhov kub thiab txias. Ua ntej, teeb tsa emissivity ε =1}}} ε hloov kho qhov kub thiab txias nrog kev ntsuas kub. Nyeem qhov tseem ceeb ntawm ε {2}} thiab hloov kho tau ntau dua lossis sib npaug ntawm txhua lub calibration taw tes, thiab tom qab ntawd coj cov ntaub ntawv kev ua haujlwm. Rau qhov ntsuas kub uas nws qhov ntsuas yuam kev thiab kev rov ua kom tau raws li qhov yuav tsum tau ua, cim nws tus nqi.
