Kev thov ntawm Infrared Thermometers hauv Kev Lag Luam Hlau
Kev ntsuas kub yuav tsum tau ua hauv ntau cov txheej txheem ntawm kev lag luam steel. Thermocouples yog siv nyob rau hauv feem ntau. Txawm li cas los xij, kev ntsuas kev sib cuag tsis muaj peev xwm ua tau rau qee yam kev siv, vim yog txav cov hlau tsis zoo lossis qhov chaw hnyav tsis haum rau kev sojntsuam. Cov ntawv thov tshwj xeeb no tuaj yeem tau txais txiaj ntsig zoo los ntawm kev ntsuas qhov ntsuas ntawm cov duab uas siv cov duab ntsuas kub kub pyrometers.
Kev ntsuas qhov ntev thiab ntsuas qhov ntsuas kub tsis sib cuag tuaj yeem ua ke zoo rau qee cov txheej txheem steel, xws li cov cua sov rauv thiab dov mills. High-temperature imaging pyrometers flexibly integrate tshwj xeeb video imaging nrog infrared ntsuas kub, ua ib tug zoo heev cuab tam rau optimized xyuas thiab ntsuas kub functions. Qhov kev sib koom ua ke no qhib txoj hauv kev tshiab rau cov hlau mills uas tsis tau siv lub koob yees duab yav dhau los, tshwj xeeb tshaj yog pab txhawb kev kho cua sov. Cov hauv qab no tsom mus rau cov chaw muaj peev xwm siv cov duab ntsuas kub siab pyrometers hauv cov nroj tsuag steel, thiab qhia txog qhov ntsuas kub rau cov khoom thiab cov kua hlau.
Kev Lag Luam Hlau & Kev Ntsuas Kub
Feem ntau hais lus, nws yog ib qho nyuaj rau kev ntsuas kub ntawm cov hlau nrog cov ntsuas kub infrared vim cov hlau tsis tshua muaj emissivity. Emissivity yog ib yam khoom vaj khoom tsev uas qhia tau hais tias ntau npaum li cas infrared tawg yog emission piv nrog ib tug blackbody (ib yam khoom uas muaj emissivity ntawm 1, sawv cev rau ib tug zoo tagnrho radiator). Qhov siab dua tus nqi emissivity, qhov ntau dua lub zog ncav cuag lub ntes. Yeej, emissivity ntau dua ua rau qhov ntsuas kub ntawm lub hom phiaj yooj yim dua.
Rau cov khoom siv steel, emissivity sib txawv nrog qhov kub thiab txias, qhov chaw saum npoo thiab steel tshuaj muaj pes tsawg leeg. Surface condition yog ib qho txawv txav uas cuam tshuam rau emissivity. Piv txwv li, unoxidized stainless hlau (raws li ua nyob rau hauv factories) muaj ib tug emissivity ntawm kwv yees li 0.4. Rau qhov hnyav oxidized (tsaus) qhov chaw, tus nqi no nce mus rau 0.8. Rau polished (ci) nto, emissivity poob rau 0.2. High-temperature imaging pyrometers tso cai hloov pauv hloov pauv ntawm emissivity rau cov cheeb tsam tus cursor xaiv ntawm txhua lub davhlau ya nyob twg screen. Kev nyeem ntawv ntsuas kub zoo tuaj yeem tau txais ntev npaum li qhov tsis muaj thiab cov cim qhia ntawm cov khoom siv raw tau paub.
