Kev soj ntsuam ntawm kev siv niaj hnub ntawm infrared thermometer technology
Infrared tus pas ntsuas kub los ntawm qhov system optical, photodetector, teeb liab amplifier thiab teeb liab ua, tso zis tso zis thiab lwm yam khoom. Optical system convergence ntawm nws daim teb ntawm kev pom ntawm lub hom phiaj infrared hluav taws xob hluav taws xob, qhov loj ntawm qhov chaw saib los ntawm tus pas ntsuas kub qhov muag qhov chaw thiab lawv qhov chaw los txiav txim. Lub zog infrared yog tsom rau lub photodetector thiab hloov mus rau hauv cov teeb liab hluav taws xob sib xws. Cov teeb liab no tau hloov mus rau qhov ntsuas kub ntawm lub hom phiaj tom qab dhau los ntawm amplifiers thiab teeb liab ua circuits thiab raug kho rau lub hom phiaj emissivity raws li algorithm ntawm qhov ntsuas qhov kev kho sab hauv.
Nyob rau hauv qhov xwm txheej, tag nrho cov khoom uas muaj qhov kub thiab txias tshaj xoom yog tas li emitting infrared hluav taws xob hluav taws xob mus rau qhov chaw nyob ib puag ncig. Qhov loj ntawm cov khoom lub zog hluav taws xob infrared thiab nws qhov kev faib tawm los ntawm lub wavelength muaj kev sib raug zoo nrog nws qhov kub thiab txias. Yog li ntawd, los ntawm kev ntsuas ntawm lub zog infrared radiated los ntawm cov khoom nws tus kheej, nws yuav muaj peev xwm txiav txim siab nws qhov kub thiab txias, uas yog lub hom phiaj rau kev ntsuas kub ntawm infrared radiation.
Blackbody yog qhov zoo tshaj plaws radiator, uas absorbs tag nrho cov wavelengths ntawm radiant zog, tsis muaj zog xav txog thiab kis tau tus mob, nws nto emissivity ntawm 1. Txawm li cas los xij, qhov muaj nyob ntawm cov khoom tiag tiag hauv qhov xwm txheej, yuav luag txhua tus tsis yog lub cev dub, txhawm rau kom paub meej thiab tau txais kev faib tawm ntawm infrared radiation txoj cai, hauv kev tshawb fawb theoretical yuav tsum xaiv cov qauv tsim nyog, uas yog Planck muab tso rau hauv lub cev kab noj hniav hluav taws xob. quantization vibronic qauv, uas coj mus rau Planck txoj cai ntawm lub blackbody hluav taws xob, uas yog, lub wavelength ntawm lub blackbody spectral radiance, qhov no yog tag nrho cov infrared hluav taws xob txoj kev xav ntawm qhov taw tes ntawm kev tawm mus, nws yog hu ua Blackbody hluav taws xob Qhov no yog qhov pib taw tes rau tag nrho cov. txoj kev xav ntawm infrared tawg, yog li nws yog hu ua txoj cai ntawm blackbody hluav taws xob. Tag nrho cov khoom siv hluav taws xob tiag tiag ntxiv rau kev cia siab rau lub wavelength ntawm cov hluav taws xob thiab qhov kub thiab txias ntawm cov khoom, tab sis kuj nrog cov khoom ntawm cov khoom siv, kev npaj, txheej txheem thermal, nrog rau lub xeev saum npoo thiab ib puag ncig thiab lwm yam. .
Kev ntsuas kub infrared siv qhov ntsuas qhov taw tes-los ntawm-taw tes, nyob rau hauv uas cov hluav taws xob hluav taws xob los ntawm ib cheeb tsam hauv cheeb tsam ntawm ib qho khoom yog tsom rau ntawm ib qho kev ntes thiab lub zog hluav taws xob hloov mus rau qhov kub los ntawm qhov paub emissivity ntawm cov khoom. Vim tias cov khoom yuav raug kuaj pom, qhov kev ntsuas ntau thiab kev siv ntau zaus, cov ntsuas kub infrared zoo li tus qauv tsim thiab cov qauv sab hauv tsis zoo ib yam, tab sis cov qauv yooj yim zoo sib xws, feem ntau suav nrog optical systems, photodetectors, teeb liab amplifiers thiab teeb liab ua. , tso zis tso zis thiab lwm yam khoom. Infrared hluav taws xob emitted los ntawm lub radiator. Nyob rau hauv lub kho qhov muag system, lub modulator rau modulate lub infrared radiation turnover hluav taws xob, los ntawm lub detector mus rau hauv lub coj hluav taws xob teeb liab. Lub teeb liab los ntawm lub amplifier thiab teeb liab ua circuits, thiab nyob rau hauv raws li lub algorithm nyob rau hauv lub ntsuas thiab lub hom phiaj emissivity kho mus rau hauv lub kub tus nqi ntawm lub hom phiaj yuav tsum tau ntsuas.
Kev ua haujlwm yooj yim, siv yooj yim: tus pas ntsuas kub infrared yuav tsum intuitive, yooj yim ua haujlwm, yooj yim rau siv los ntawm tus neeg teb xov tooj, uas portable infrared tus pas ntsuas kub yog ib txheej ntsuas kub thiab tso zis tso zis ua ib qho me me, hnav, nqa los ntawm tus neeg mus nqa cov cuab yeej rau kev ntsuas qhov kub thiab txias hauv vaj huam sib luag tuaj yeem tso saib qhov kub thiab txias ntawm cov ntaub ntawv kub ntau, thiab qee qhov tuaj yeem ua haujlwm remotely lossis los ntawm lub khoos phis tawj software.
Nyob rau hauv cov ntaub ntawv ntawm hnyav thiab complex ib puag ncig, ib tug system nrog nyias ntsuas kub ntsuas lub taub hau thiab cov lus qhia yuav xaiv tau yooj yim ntawm installation thiab configuration. Cov ntawv tso zis hluav taws xob tuaj yeem raug xaiv kom phim cov cuab yeej tswj tam sim no. Calibration ntawm infrared hluav taws xob pyrometer: Lub infrared pyrometer yuav tsum tau calibrated thiaj li yuav kom nws pom qhov kub ntawm lub hom phiaj ntsuas. Yog tias lub pyrometer siv tau siv thiab ntsuas qhov ntsuas kub tsis zoo, nws yuav tsum tau xa rov qab mus rau cov chaw tsim khoom lossis chaw saib xyuas kom rov ntsuas dua.
