Cov lus qhia kom paub tseeb qhov ntsuas qhov tseeb ntawm Infrared Thermometers
Lub hauv paus ntsiab lus tseem ceeb ntawm infrared tus pas ntsuas kub thev naus laus zis yog ua raws li lub zog emission infrared. Qhov tseem ceeb tshaj plaws yog emissivity, thaj tsam ntawm qhov pom, qhov deb ntawm qhov chaw thiab qhov chaw.
Emissivity: Txhua yam khoom muaj kev cuam tshuam, xa tawm thiab tawg lub zog, thiab tsuas yog lub zog hluav taws xob qhia qhov kub ntawm qhov khoom.
Thaum lub ntsuas kub infrared ntsuas qhov kub thiab txias, qhov ntsuas tau txais tag nrho peb hom zog. Yog li ntawd, tag nrho cov ntsuas kub infrared yuav tsum tau hloov kho kom nyeem tsuas yog lub zog hluav taws xob. Kev ntsuas qhov yuam kev feem ntau yog tshwm sim los ntawm lub zog infrared uas cuam tshuam los ntawm lwm qhov chaw teeb pom kev zoo. Qee qhov ntsuas kub infrared txhawb kho emissivity; emissivity qhov tseem ceeb rau ntau yam ntaub ntawv tuaj yeem pom nyob rau hauv cov ntawv luam tawm emissivity. Lwm cov cuab yeej muaj qhov ruaj khov preset emissivity ntawm 0.95. Tus nqi no siv rau qhov kub thiab txias ntawm feem ntau cov ntaub ntawv organic, xim los yog oxidized nto. Rau cov chaw zoo li no, siv daim kab xev lossis matte dub xim rau ntawm qhov ntsuas qhov chaw rau kev them nyiaj. Thaum cov ntaub nplaum los yog xim pleev xim rau qhov kub thiab txias tib yam li cov khoom siv hauv paus, ntsuas qhov kub ntawm daim kab xev los yog pleev xim rau saum npoo muab nws qhov kub thiab txias.
Distance-to-spot ratio: Lub tshuab kho qhov muag ntawm lub ntsuas kub infrared sau lub zog los ntawm qhov ntsuas qhov chaw thiab tsom nws mus rau qhov ntsuas. Kev daws teeb meem kho qhov muag txhais tau tias yog qhov piv ntawm qhov kev ncua deb ntawm lub ntsuas kub infrared mus rau qhov khoom thiab qhov ntsuas qhov loj me (D:S). Qhov sib piv ntau dua, qhov zoo dua qhov kev daws teeb meem ntawm tus pas ntsuas kub infrared thiab qhov ntsuas qhov chaw me me. Laser aiming tsuas yog siv los pab lub hom phiaj ntsuas ntsuas.
Qhov kev nce qib tshiab tshaj plaws hauv infrared optics qhia txog qhov muaj peev xwm ua kom pom tseeb, ua kom raug ntsuas ntawm cov phiaj xwm me me thiab tiv thaiv kev cuam tshuam ntawm qhov kub thiab txias.
Field of view: Xyuas kom lub hom phiaj loj dua qhov chaw loj ntawm lub ntsuas kub infrared thaum ntsuas. Lub hom phiaj me dua, qhov ze ntawm tus pas ntsuas kub yuav tsum yog rau nws. Thaum qhov tseeb yog qhov tseem ceeb, xyuas kom lub hom phiaj yog tsawg kawg ob zaug ntawm qhov chaw loj.
