Kev taw qhia txog kev txiav txim siab wavelength ntau yam ntawm infrared thermometers
Lub emissivity thiab nto thaj chaw ntawm tus pas ntsuas kub infrared lub hom phiaj cov khoom txiav txim siab tus pas ntsuas kub lub spectral teb, los yog wavelength. Rau siab reflectivity alloy cov ntaub ntawv, muaj tsawg los yog sib txawv emissivity. Hauv qhov chaw kub kub, qhov zoo tshaj plaws wavelength rau ntsuas cov khoom siv hlau yog ze-infrared, thiab 0.18-1.0μm wavelength tuaj yeem siv tau. Lwm qhov chaw kub muaj nyob nrog 1.6μm, 2.2μm thiab 3.9μm wavelengths.
Tus pas ntsuas kub infrared Vim tias qee cov ntaub ntawv yog pob tshab ntawm qee qhov wavelengths, lub zog infrared yuav nkag mus rau cov ntaub ntawv no, yog li yuav tsum xaiv lub wavelength tshwj xeeb rau cov khoom siv no. Piv txwv li, thaum ntsuas qhov kub thiab txias ntawm iav, siv 10μm, 2.2μm thiab 3.9μm wavelengths (lub khob yuav tsum ntsuas yuav tsum yog tuab heev, txwv tsis pub nws yuav kis tau los ntawm); Thaum ntsuas qhov kub ntawm iav, siv 5.0μm wavelength; thaum ntsuas qhov ntsuas kub tsawg, nws tsim nyog siv 8-14μm wavelength; thiab piv txwv li Lub wavelength ntawm 3.43μm yog siv los ntsuas polyethylene yas zaj duab xis, thiab lub wavelength ntawm 4.3μm los yog 7.9μm yog siv rau polyester. Yog tias lub thickness ntau tshaj 0.4mm, lub wavelength ntawm 8-14μm raug xaiv; Piv txwv li, qhov nqaim 4.24-4.3μm wavelength yog siv los ntsuas C02 hauv nplaim taws, qhov nqaim 4.64μm wavelength yog siv los ntsuas C0 hauv nplaim taws, thiab 4.47μm wavelength yog siv los ntsuas N02 hauv qhov nplaim taws.
Lub hauv paus ntsiab lus ua haujlwm ntawm tus pas ntsuas kub infrared yog qhov yooj yim heev. Nws siv thev naus laus zis infrared kom sai thiab yooj yim ntsuas qhov kub ntawm cov khoom. Tau txais kev ntsuas kub sai sai yam tsis muaj kev sib cuag nrog cov khoom ntsuas. Tsuas yog tsom, nias lub cim thiab nyeem cov ntaub ntawv ntsuas kub ntawm LCD zaub. Cov ntsuas kub infrared yog lub teeb yuag, me me, siv tau yooj yim, thiab tuaj yeem ntsuas qhov kub, txaus ntshai, lossis nyuaj rau cov khoom tsis muaj paug lossis ua rau cov khoom raug ntsuas. Cov ntsuas kub infrared tuaj yeem siv sijhawm ntau nyeem ib ob, thaum tiv tauj cov ntsuas kub siv sijhawm ob peb feeb ib feeb. Nws tau txais lub zog infrared pom tsis pom los ntawm ntau yam khoom lawv tus kheej. Infrared tawg yog ib feem ntawm cov electromagnetic spectrum, xws li wireless microwaves, ultraviolet, xov tooj cua tsis, pom lub teeb, R-rays thiab X-rays. Infrared rays nyob nruab nrab ntawm lub teeb pom kev thiab xov tooj cua tsis muaj zog. Lub wavelength ntawm infrared rays feem ntau qhia nyob rau hauv microns, thiab lub wavelength ntau yog 0.7 microns-1000 microns. Qhov tseeb, 0.7 micron-14 micron band yog siv rau hauv cov ntsuas kub infrared. Nws raug nquahu kom siv Guangzhou Hongcheng CEM infrared tus pas ntsuas kub series cov khoom, uas tuaj yeem ntsuas qhov kub ntawm -50 thiab 2200 degrees. Kev ntsuas yog qhov tseeb thiab yooj yim rau kev khiav lag luam.
