Taw qhia rau kev ua tau zoo thiab thov kev txheeb xyuas ntawm tus ntsuas kub infrared
Hais lus ntawm infrared thermometers, Kuv ntseeg tias txhua tus paub nrog lawv. Cov khoom lag luam no, uas ntsuas qhov chaw nyob ntawm qhov chaw ntawm cov khoom ntsuas ntawm lawv cov kev tsim tawm, tsis tau hais tawm hauv lawv cov kev tsim tawm, thiab tuaj yeem hais tau tias yog cov khoom lag luam uas yog "ntau tshaj li ib txwm muaj".
Puas yog cov khoom lag luam ib txwm muaj yooj yim?
1. Cov nyiaj them rau ib puag ncig
Nyob rau hauv cov xwm txheej twg yog ib puag ncig qhov kub yuav tsum tau?
Feem ntau hais lus, thaum lub ambient kub tshaj qhov ntsuas qhov ntsuas kub, kev them nyiaj ib puag ncig muaj nuj nqi yuav tsum tau siv. Feem ntau, cov khoom lag luam siab muaj cov txuj ci no. Qhov xwm txheej ib qho yog ntsuas ntsuas qhov kub ntawm cov hlau ntim hlau hauv cov cub hluav taws xob hauv lub cub tawg. Hauv hom ntawv thov no, peb feem ntau siv marathon series boilometers kom ncaj qha ntsuas ntsuas kub ntawm cov cua sov los ntsuas qhov ntsuas kub ntawm cov phab ntsa cub. Los ntawm kev ua kom sov phab ntsa kub hauv lub sijhawm tiag tiag hauv lub sijhawm tiag tiag li {2}} v teeb liab, ntsuas kub thiab kub thiab txias.
2. Sab Nraud ntawm Emissivity
Qhov emissivity ntawm cov khoom sib txawv yuav txawv, thiab txhawm rau tau txais qhov ntsuas kub tiag tiag, nws yog feem ntau yuav tsum tau teeb tsa lub emissivity ntawm cov khoom siv.
Tus pas ntsuas kub nrog cov ntsuas hluav taws xob sab nraud rau kev ua emissivity tuaj yeem tswj hwm tus nqi 0.1} {{} {} {{{{{}} emissivity. Los ntawm kev tswj cov teeb liab los ntawm kev teeb liab sab nraud, peb tuaj yeem ua tiav kev hloov kho tsis siv neeg ntawm kev tshwm sim emissivity, yog li tau txais ntau qhov tseeb kub ntsuas.
