Distinguishing ntawm tib neeg thiab industrial thermometers
Tib neeg tus pas ntsuas kub infrared feem ntau yog siv los ntsuas qhov kub ntawm tib neeg lub cev, thaum lub ntsuas kub infrared muaj, raws li lub npe qhia, feem ntau yog siv hauv kev lag luam. Txawm li cas los xij, nws yuav tsum tau qhia meej tias tsis muaj qhov sib txawv ntawm cov kws kho mob tshwj xeeb lossis cov khoom siv hluav taws xob infrared, vim tias cov qauv tsim khoom ntawm cov ntsuas kub infrared zoo ib yam. Tsuas muaj qhov sib txawv ntawm qhov siab precision, siab nyob deb coefficient piv, thiab high-performance infrared tus pas ntsuas kub thiab tsawg precision, tsis tshua muaj coefficient piv, thiab tsis tshua muaj kev ua tau zoo infrared tus pas ntsuas kub. Ntev npaum li qhov emissivity ntawm tus pas ntsuas kub infrared tau teem rau 0.95 (qhov emissivity ntawm tib neeg daim tawv nqaij feem ntau yog tus nqi no, thiab txawm tias muaj qhov sib txawv, qhov cuam tshuam tsuas yog nyob rau hauv 0.2 degrees), nws ua tau raws li qhov yuav tsum tau ua rau tib neeg ntsuas kub.
Ib qho yog tias tib neeg tus pas ntsuas kub infrared muaj qhov ntsuas kub me me ntawm 30-42.5 degrees, tab sis qhov tseeb qhov tseeb yog siab. Cov ntsuas kub infrared muaj ntau yam, xws li tuaj yeem ntsuas -50 txog 2200 degrees.
Qhov thib ob yog tias tib neeg tus pas ntsuas kub infrared yuav tsum nyob ze rau tib neeg lub cev, tsis pub dhau 1-15cm, thiab cov ntsuas kub infrared yuav tsum siab dua 1M. Yog tias ntsuas qhov kub ntawm cov hlau molten, tib neeg tsis tuaj yeem nyob ze, thiab qee qhov xav tau txog 10M. Kev ntsuas ze thiab deb feem ntau yog hais txog qhov siv ntawm infrared nthwv dej tawm los ntawm tus pas ntsuas kub. Lub infrared nthwv dej ntawm tib neeg lub cev infrared tus pas ntsuas kub muaj zog heev thiab muaj kev phom sij rau tib neeg lub cev, yog li nws tsis tsim nyog.
Yog li ntawd, peb tuaj yeem xaiv lub ntsuas kub kom haum raws li qhov xav tau, uas tuaj yeem muab faib ua peb yam: ntsuas kev ua haujlwm, xws li qhov kub thiab txias, qhov loj me, ua haujlwm wavelength, ntsuas qhov tseeb, lub sijhawm teb, thiab lwm yam; Nyob rau hauv cov nqe lus ntawm ib puag ncig thiab kev ua haujlwm, xws li ib puag ncig kub, qhov rais, tso saib thiab tso zis, thiab cov khoom siv tiv thaiv; Lwm cov kev xaiv, xws li kev yooj yim ntawm kev siv, kev saib xyuas thiab calibration kev ua tau zoo, thiab tus nqi, kuj muaj qee yam cuam tshuam rau kev xaiv cov ntsuas kub infrared.
