Analysis ntawm Distance Coefficient ntawm Infrared Thermometer
Qhov kev ncua deb coefficient ntawm tus pas ntsuas kub infrared yog txiav txim los ntawm D: S, D yog nruab nrab ntawm qhov kev sojntsuam ntawm tus pas ntsuas kub thiab lub hom phiaj, thiab S sawv cev rau txoj kab uas hla ntawm qhov chaw.
Analysis ntawm Distance Coefficient ntawm Infrared Thermometer
Kom nkag siab yooj yim, siv lub teeb nyem ua piv txwv. Lub teeb ntawm lub teeb yog qhov sib txawv, thiab qhov deb ntawm nws yog, qhov loj dua qhov chaw ntawm qhov khoom yuav yog. D yog qhov kev ncua deb ntawm lub teeb nyem mus rau qhov khoom, S yog txoj kab uas hla ntawm qhov chaw, thiab lawv qhov piv yog hu ua qhov sib txawv coefficient. Qhov txawv yog tias tus pas ntsuas kub infrared ntshiab absorbs infrared nthwv dej radiated los ntawm cov khoom, thaum lub teeb nyem emits pom lub teeb.
Thaum siv lub ntsuas kub infrared, lub hom phiaj ntsuas yuav tsum ua kom tiav qhov kev pom, feem ntau yog 1.5 npaug ntawm kev sib raug zoo.
Analysis ntawm Distance Coefficient ntawm Infrared Thermometer
Rau ib tug pyrometer nrog ib tug taag focal ntev, lub focal point ntawm optical system yog qhov tsawg kawg nkaus qhov chaw, thiab qhov chaw yuav nce nyob ze thiab deb ntawm lub focal point, thiab muaj ob tug nyob deb coefficients. Yog li ntawd, txhawm rau txhawm rau ntsuas qhov ntsuas kub ntawm qhov chaw nyob ze thiab deb ntawm qhov ua kom pom tseeb, qhov loj ntawm lub hom phiaj ntsuas yuav tsum loj dua qhov chaw loj ntawm qhov tsom; lub ntsuas kub zoom muaj qhov ua kom pom tseeb yam tsawg kawg nkaus, uas tuaj yeem hloov kho raws li qhov kev ncua deb ntawm lub hom phiaj.
Yog hais tias tus pas ntsuas kub yuav tsum tau muab ntsia kom deb ntawm lub hom phiaj vim yog ib puag ncig, thiab nws yog ib qho tsim nyog los ntsuas lub hom phiaj me me, tus pas ntsuas kub uas muaj kev daws teeb meem siab yuav tsum tau xaiv. Qhov siab dua qhov kev daws teeb meem kho qhov muag, qhov siab dua qhov D: S piv. Tus nqi ntawm tus pas ntsuas kub kuj tseem siab dua.
Muaj ib lub laser liab taw tes rau ntawm tus pas ntsuas kub, uas yog siv rau lub hom phiaj qhia. Ntau tus neeg uas tsis paub qhov chaw xav tias qhov ntsuas kub yog qhov ntsuas kub ntawm qhov chaw ntawd. Qhov tseeb, qhov no yog kev nkag siab yuam kev. Qhov ntsuas kub nyeem yog ua tau raws li qhov taw tes ntawd. Qhov taw tes yog qhov nruab nrab ntawm lub voj voog, qhov nruab nrab kub ntawm lub voj voog nrog txoj kab uas hla ntawm S, uas yog vim li cas qhov ntsuas kub ntsuas ntawm tib lub ntsiab lus txawv thaum nws nyob deb thiab ze rau nws, vim qhov S tau hloov pauv (tus nrug sib txawv, lub zog ntawm infrared nthwv dej Attenuation kuj plays lub luag hauj lwm).
