Cov yam ntxwv cuam tshuam rau Emissivity thiab Infrared System Taw Qhia rau Infrared Thermometers
Lub ntsiab tseem ceeb cuam tshuam rau emissivity yog: hom khoom, nto roughness, lub cev thiab tshuaj qauv, thiab cov khoom thickness.
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 pyrometers yog proportional rau tus nqi ntawm hluav taws xob nyob rau hauv ib tug band; dual-xim pyrometers yog proportional rau qhov piv ntawm tus nqi hluav taws xob hauv ob pawg.
Infrared system: Lub ntsuas kub infrared yog tsim los ntawm kev kho qhov muag, photodetector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm qhov chaw. Lub tshuab kho qhov muag sib sau ua ke lub hom phiaj infrared hluav taws xob hluav taws xob hauv nws qhov chaw saib, thiab qhov loj ntawm qhov kev pom yog txiav txim 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 hloov mus rau hauv cov teeb liab hluav taws xob sib xws. Lub teeb liab dhau los ntawm lub amplifier thiab teeb liab ua Circuit Court, thiab hloov mus rau hauv tus nqi kub ntawm qhov ntsuas lub hom phiaj tom qab raug kho raws li algorithm ntawm kev kho sab hauv ntawm lub ntsuas thiab emissivity ntawm lub hom phiaj.
