Dab tsi yog lub hauv paus ntsiab lus ntawm infrared tus pas ntsuas kub?
Dab tsi yog lub hauv paus ntsiab lus ntawm infrared thermometers? Txhua yam khoom uas muaj qhov kub siab tshaj qhov xoom yuav tsis tu ncua emit infrared hluav taws xob hluav taws xob rau hauv qhov chaw nyob ib puag ncig nws. Qhov loj ntawm lub zog hluav taws xob infrared ntawm lub hom phiaj thiab nws qhov kev faib tawm ntawm lub wavelength muaj kev sib raug zoo nrog qhov kub thiab txias ntawm lub hom phiaj. Yog li, los ntawm kev ntsuas lub zog infrared radiated los ntawm cov khoom nws tus kheej, qhov kub thiab txias ntawm cov khoom tuaj yeem ntsuas qhov tseeb, uas yog lub hom phiaj ntawm kev ntsuas qhov ntsuas kub infrared.
Lub cev dub yog lub tshuab hluav taws xob zoo tshaj plaws, nws tuaj yeem nqus cov hluav taws xob hluav taws xob ntawm txhua lub wavelengths, thiab nws qhov emissivity yog
1. Nws tuaj yeem pom los ntawm daim duab faib tawm ntawm lub cev dub hluav taws xob spectrum nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias uas tag nrho cov hluav taws xob hluav taws xob nce sai heev thaum qhov kub thiab txias (tag nrho cov hluav taws xob hluav taws xob nyob hauv cheeb tsam ncig los ntawm qhov sib thooj nkhaus thiab lub wavelength kev sib koom ua ke nce sai heev. ); lub monochromatic hluav taws xob flux muaj Thaum qhov kub thiab txias nce, tus nqi huab hwm coj mus rau lub wavelength txav mus rau qhov kev taw qhia luv-yoj. Yog li ntawd, cov hlua uas tsim los rau qhov ntsuas ntawm qhov kub thiab txias sib txawv.
Tus pas ntsuas kub infrared txais ib txoj kev tsom xam point-by-point, uas yog, lub hauv paus thermal hluav taws xob ntawm lub hom phiaj yog concentrated nyob rau hauv ib tug detector, thiab lub hwj chim hluav taws xob hloov mus rau hauv qhov kub thiab txias los ntawm kev paub txog cov emission tus nqi ntawm lub hom phiaj. Nws cov qauv yooj yim yog tsim los ntawm optical system, photodetector, teeb liab amplifier, teeb liab ua, tso zis tso zis thiab lwm yam.
Tom qab cov hluav taws xob infrared tso tawm los ntawm lub tshuab hluav taws xob nkag mus rau hauv qhov muag pom, cov hluav taws xob infrared yog hloov mus rau hauv cov hluav taws xob hloov hluav taws xob los ntawm lub tshuab hluav taws xob, uas tau hloov mus rau hauv cov teeb liab hluav taws xob sib txuas los ntawm tus ntes. Tom qab lub amplifier thiab teeb liab ua Circuit Court, nws raug kho raws li lub internal algorithm ntawm lub ntsuas thiab lub hom phiaj emissivity, thiab hloov mus rau hauv tus nqi kub ntawm lub hom phiaj ntsuas.
Infrared thermometers feem ntau muaj peb series: portable, on-line thiab scanning, thiab yog nruab nrog ntau yam kev xaiv thiab computer software. Txhua series muaj txawv qauv thiab specifications. Kev xaiv cov ntsuas kub infrared tau muab faib ua ob yam: ib qho yog cov ntsuas kev ua haujlwm, xws li qhov kub thiab txias, qhov loj me, ua haujlwm wavelength, ntsuas qhov tseeb, thiab lub sijhawm teb; lwm yam yog ib puag ncig tej yam kev mob, xws li ambient kub, qhov rais, tso zis tso zis, thiab tiv thaiv accessories tos.
