Kev txiav txim siab ib puag ncig rau infrared thermometers
Cov ntsuas hluav taws xob ib puag ncig uas tus pas ntsuas kub yog qhov cuam tshuam rau kev ntsuas ntsuas thiab txwv tsis pub nws muaj kev puas tsuaj rau tus pas ntsuas kub. Thaum qhov kub thiab txias dhau lawm thiab muaj plua plav, haus luam yeeb, thiab cov tshuab cua txias muab los ntawm cov khw muag khoom tau raug xaiv. Cov ntawv txuas no tuaj yeem ua rau muaj kev cuam tshuam ib puag ncig ib puag ncig thiab tiv thaiv tus pas ntsuas kub, ua tiav qhov ntsuas kub. Thaum txiav txim kev txuas, cov kev pabcuam qauv yuav tsum tau thov kom ntau li ntau tau los txo tus nqi teeb tsa. Thaum haus luam yeeb, hmoov av, lossis lwm cov lus txo qhov ntsuas hluav taws xob lub zog yog qhov kev xaiv zoo tshaj plaws. Fiber ntau Optic Dual Xim Cov thermometers yog qhov kev xaiv zoo tshaj plaws rau cov chaw uas muaj suab nrov, electromagnetic teb, kev co, lossis lwm yam mob hnyav.
Nyob rau hauv hnyav thiab txoj kev ib puag ncig ib puag ncig, ib txoj kab ke nrog cov khoom siv kub thiab cov khoom siv tau xaiv tau yooj yim thiab kev teeb tsa. Lub teeb liab tso zis daim ntawv uas phim cov khoom tswj tam sim no tuaj yeem xaiv tau.
Txheeb xyuas wavelength ntau yam
Lub Emissivity Emissivity thiab cov khoom saum npoo ntawm cov khoom siv hauv lub hom phiaj txiav txim siab qhov kev teb zoo nkauj lossis yoj ntawm tus pas ntsuas kub. Txog kev xav txog cov ntaub ntawv alloy, muaj qhov qis lossis sib txawv lossis sib txawv. Hauv cov chaw kub-thaj chaw, cov wavelengtength rau ntsuas cov khoom siv hlau yog ze li {2}} hli wavelength. Lwm qhov kub thiab txias thiab siv wavelengths ntawm 1.6mm, 2.2mm, thiab 3.9mm. Vim qee cov ntaub ntawv tau pob tshab rau qee lub zog, lub zog tshwj xeeb tuaj yeem xaiv cov khoom siv no, thiab cov wavel tshwj xeeb yuav tsum tau xaiv rau cov ntaub ntawv no. Yog hais tias ntsuas ntsuas qhov kub ntawm lub khob, xaiv wavelengths ntawm 1. {4}} hnab yuav tsum yog tuab heev, nws yuav dhau mus dhau los); Ntsuas qhov kub hauv lub khob uas siv lub wavelength ntawm 5. 0 hli; Nws raug nquahu kom siv nthwv dej ntawm 8-14 hli rau ntsuas cov chaw qis; Piv txwv li, thaum ntsuas Polyethylene yas zaj duab xis, nthwv cua ntawm 3.43mm yog siv, thaum lub siab tawv ntawm 4.3mm lossis 7.9mm yog siv. Xaiv wavelengths ntawm {{26} pa rau thicknesses tshaj 0. 4mm; 4mm; Piv txwv li, CO2 hauv cov nplaim taws tau ntsuas siv lub ntsej muag nqaim ntawm 4.}}}}}.}}}.}}}
Txiav txim siab teb lub sijhawm
Lub sijhawm teb sawv cev rau cov tshuaj tiv thaiv ceev ntawm tus pas ntsuas kub infrared los hloov ntawm 95% ntawm lub zog uas yuav tsum tau mus txog kev nyeem ntawv kawg. Nws muaj feem xyuam rau lub sijhawm tas li ntawm cov photodetector, teeb liab kev ua Circuital, thiab Display System. Yog tias lub hom phiaj txav ntawm lub nrawm nrawm lossis thaum ntsuas qhov ntsuas kub sai sai, txwv tsis pub nws yuav txo qis kev ntsuas qhov raug. Tab sis tsis yog txhua daim ntawv thov yuav tsum tau teb nrawm infrared thermometers. Thaum muaj thermal inertia nyob rau hauv ib qho chaw nyob lossis phiaj txheej txheem thermal, lub sijhawm teb ntawm tus pas ntsuas kub tuaj yeem so. Yog li ntawd, kev xaiv ntawm lub sijhawm teb rau lub ntsuas kub infrared yuav tsum tau yoog raws li qhov xwm txheej ntawm lub hom phiaj ntsuas.
