Ambient Radiation ntawm Infrared Thermometers

 

Hauv kev tshawb nrhiav infrared ntawm cov cuab yeej siv hluav taws xob sab nraum zoov, cov hluav taws xob infrared tau txais los ntawm cov cuab yeej tshawb nrhiav suav nrog tsis yog tsuas yog cov hluav taws xob tawm los ntawm cov khoom sib txuas ntawm cov cuab yeej ntsuas nws tus kheej, tab sis kuj muaj kev xav los ntawm lwm qhov chaw ntawm cov khoom siv thiab cov keeb kwm yav dhau, thiab. direct tuaj hnub ci hluav taws xob. Cov hluav taws xob no yuav cuam tshuam rau qhov kub thiab txias ntawm ib feem ntawm lub cuab yeej yuav tsum tau kuaj, thiab ua rau muaj kev ua yuam kev hauv kev kuaj pom. Txhawm rau txo qhov cuam tshuam ntawm ib puag ncig thiab hluav taws xob tom qab, yuav tsum tau ua raws li cov kev tiv thaiv nram qab no: Kev kuaj pom ntawm cov khoom siv hluav taws xob sab nraum zoov yuav tsum tau ua rau hnub huab cua lossis yav tsaus ntuj thaum tsis muaj lub teeb nyob ib puag ncig hnub poob. Nyob rau hauv txoj kev no, qhov xwm txheej ncaj qha, cuam tshuam thiab tawg tawg ntawm hnub ci hluav taws xob tuaj yeem tiv thaiv. Rau cov khoom siv sab hauv tsev, teeb pom kev zoo tuaj yeem raug tua, thiab lwm yam kev cuam tshuam hluav taws xob tuaj yeem zam tau.


Rau cov khoom siv uas muaj kev cuam tshuam zoo heev, kev ntsuas tsim nyog yuav tsum tau coj los txo qhov cuam tshuam ntawm hnub ci hluav taws xob thiab hluav taws xob los ntawm ib puag ncig cov khoom kub. Los yog hloov lub kaum sab xis nrhiav kom pom lub kaum sab xis zoo tshaj plaws kom tsis txhob muaj kev cuam tshuam rau kev tshawb pom.


Txhawm rau txo cov hluav taws xob hluav taws xob ntawm lub hnub ci hluav taws xob thiab qhov chaw nyob ib puag ncig qhov kub thiab txias tom qab, kev tiv thaiv kev tiv thaiv tsim nyog tuaj yeem raug coj los siv thaum kuaj pom, los yog cov lim dej infrared tsim nyog tuaj yeem ntsia tau rau ntawm cov cuab yeej hluav taws xob infrared thermal imaging los lim tawm lub hnub thiab lwm yam hluav taws xob tom qab.


Xaiv ib qho cuab yeej uas tsim nyog thiab qhov kev ncua deb ntawm kev tshawb nrhiav, kom cov khoom siv kuaj pom muaj nyob rau hauv qhov kev pom ntawm qhov ntsuas, yog li txo qhov cuam tshuam ntawm cov hluav taws xob tom qab.


Tus pas ntsuas kub infrared yog tsim los ntawm optical system, photoelectric detector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm yam. Lub tshuab kho qhov muag sib sau ua ke cov hluav taws xob sab nraud ntawm lub hom phiaj hauv nws qhov chaw saib, thiab qhov loj ntawm qhov kev pom yog txiav txim siab los ntawm qhov chaw kho qhov muag ntawm tus pas ntsuas kub thiab nws txoj hauj lwm. Lub zog infrared yog tsom rau lub photodetector thiab cov teeb liab hluav taws xob sib raug tau hloov mus rau qhov ntsuas kub ntawm lub hom phiaj sab tom qab dhau los ntawm amplifier thiab teeb liab processor Circuit Court, thiab raws li lub built-in algorithm ntawm lub ntsuas thiab lub hom phiaj emissivity kho thiab ambient. kub them nyiaj. Thaum siv lub ntsuas hluav taws xob hluav taws xob infrared los ntsuas qhov ntsuas kub ntawm lub hom phiaj, nws yog thawj zaug uas yuav tsum ntsuas qhov hluav taws xob hluav taws xob ntawm lub hom phiaj nyob rau hauv nws qhov band, thiab tom qab ntawd qhov ntsuas kub ntawm lub hom phiaj ntsuas yog xam los ntawm tus pas ntsuas kub. Monochromatic thermometers yog proportional rau tus nqi ntawm cov hluav taws xob nyob rau hauv band: dual-xim ntsuas kub yog proportional rau tus nqi hluav taws xob nyob rau hauv ob band.
