Tus Tus Kab Mob Infrared Yog Puas Yog? Vim li cas ho tsis zoo rau hauv lub nplai loj los?

Koj cov tawv nqaij feem ntau tau hais tias, "Kuv tsis kam thermometer thermometer, tus ntiv tes thooj me me ntiv tes, qhov ntsuas me me, qhov ntsuas, qhov muag ntsuag qhov muag ntsuas kub." Tab sis yog tias koj mus rau tom tsev kho mob rau kev kuaj mob , tus nais maum thiab tus muam tsis tshua siv lub tshuab ntsuas hluav taws xob los saib xyuas koj lub hauv pliaj. Mercury cov thermometers thiab cov thermometers hluav taws xob feem ntau yog qhov kev xaiv thawj zaug. Cov thermometer uas yog "siab tshaj plaws" tsis muaj peev xwm hloov tau tus pas ntsuas kub, thiaj li nrov? tau pib nrog nws txoj haujlwm ua haujlwm ...

Raws li lub npe siv, qhov tseem ceeb ntawm tus pas ntsuas kub muaj qhov ci yog qhov muag teeb ci, uas yog qhov muag tsis pom qhov muag.

Ib hom npe ntawm LCT-600 qhov kub thiab txias thermometer

Infrared tus pas ntsuas kub (network daim duab)

Thaum ntsuas qhov kub ntawm qhov khoom yog siab tshaj qhov kev xoom xoom [1], vim lub zog ntawm cov khoom siv hluav taws xob, lub zog tsim los ntawm nws tawm sab nraud hauv daim ntawv ntawm electromagnetic tsis, feem ntau yog cov duab liab qab. Raws li txoj cai Stein-Boltzmann, tag nrho lub zog tawm ntawm tus neeg dub [2] hauv chav tsev yog qhov sib npaug ntawm plaub lub hwj chim ntawm nws qhov chaw kub.

Ntawm lawv, A yog daim ntawv qhia emissivity [3], σ yog ib qho tas mus li, raws li lub ntsiab cai no, tus pas ntsuas kub muaj peev xwm indirectly ntsuas qhov thermodynamic kub ntawm qhov khoom los ntawm kev sau tag nrho cov hluav taws xob ntawm qhov ntsuas.

Yog li ntawd, qhov tseem ceeb npaum li cas hauv hluav taws xob pauv mus rau hauv tib neeg ntsuas kub? Txoj kev no tsis yog qhov nyuaj. Ua ntej tshaj plaws, koj tsuas xav muab lub ntsuas ntawm tus pas ntsuas kub ncaj qha rau ntawm qhov khoom ntsuas, thiab infrared rays generated los ntawm cov khoom yuav nquag "xa thiab tuav". Tom qab dhau los ntawm lub lim, nws yuav tsum tau sau los ntawm qhov systemelectric system thiab xa mus rau lub photodetector. Lub photodetector yuav nws hloov mus ua hluav taws xob lub teeb liab, xa mus rau lub teeb liab processor, kho los ntawm lub teeb liab processor, xa mus rau qhov system tso tawm qhov system, thiab thaum kawg hloov dua siab tshiab rau hauv qhov ntsuas kub.
