Kev piav qhia ntawm Temperature Calibration Technology rau High Temperature Annealing Furnace Thermometer

Nws tau tshaj tawm tias qhov kub-kub annealing rauv siv lub voj kaw kaw uas tsim los ntawm kev ceev cov digital PLD kub tswj, thermocouple, pyrometer, thiab qhov cua sov kom raug tswj qhov kub thiab txias. Los ntawm kev sib koom tes tswj cov teeb halogen nyob rau hauv cov cheeb tsam sib txawv, qhov sib txawv ntawm qhov kub thiab txias hauv txhua cheeb tsam tuaj yeem raug them nyiaj thaum lub sij hawm tswj qhov kub thiab txias, ua kom qhov kub ntawm cov cheeb tsam sib txawv ntawm cov substrate tsis hloov. Vim nws qhov kev teeb tsa hauv qab ntawm kab noj hniav, pyrometer tsuas tuaj yeem tau txais hluav taws xob los ntawm sab nraum qab ntawm lub substrate thiab tsis tuaj yeem tau txais hluav taws xob los ntawm lub teeb. Yog li, lub pyrometer tuaj yeem ntsuas qhov ntsuas kub ntawm lub substrate. Qhov kub thiab txias calibration txoj cai ntawm no pyrometer yog raws li nram no:
1. Taw qhia rau Pyrometer:
Lub pyrometer qhia hauv kab lus no yog lub thermal hluav taws xob hluav taws xob optical pyrometer. Thaum lub pyrometer tau txais hluav taws xob infrared los ntawm cov khoom ntsuas, lub teeb liab kho qhov muag tau lim, photoelectric hloov dua siab tshiab, thiab nthuav dav los ua lub teeb liab analog, uas yog tom qab ntawd xa mus rau lub teeb liab interface Circuit Court module ntawm lub sensor. Qhov module no ua A / D hloov dua siab tshiab ntawm lub teeb liab thiab hloov nws mus rau hauv lub teeb liab digital uas tuaj yeem lees paub los ntawm lub computer. Cov teeb liab digital pub rov qab rau lub computer yog hu ua pyrometer tawm tswv yim tus nqi hauv cov ntawv hauv qab no.
2. Temperature calibration table:
Raws li kev cai lij choj, qhov kub ntawm ib yam khoom muaj feem xyuam rau nws cov hluav taws xob thiab spectral emissivity. Rau qhov kub-kub annealing furnaces, tus nqi hluav taws xob tau txais los ntawm pyrometer feem ntau yog nyob ntawm cov khoom xws li cov khoom siv substrate, doping, ntuj oxide txheej ntawm qhov chaw, thiab kub substrate. Rau tib hom substrate (piv txwv li substrates nrog tib yam khoom, doping, thiab saum npoo ntuj oxide txheej), tus nqi hluav taws xob tau txais los ntawm pyrometer muaj feem xyuam rau lub substrate kub. Yog li ntawd, rau tib hom substrate, cov lus tawm tswv yim tus nqi ntawm pyrometer sib haum ib-rau-ib nrog rau qhov kub thiab txias substrate. Cov ntawv sau no suav nrog cov ntaub ntawv ntsuas kub ntsuas, thiab lub ntsuas kub ntsuas kub yog siv los khaws cov ntaub ntawv kev sib raug zoo ntawm ntau lub substrate kub thiab cov lus tawm tswv yim los ntawm pyrometer. Cov kub sib txawv sib txawv rau cov lus tawm tswv yim sib txawv ntawm cov pyrometer. Lub tshuab hluav taws xob kub kub annealing rauv lub computer tuaj yeem xam qhov ntsuas kub ntawm lub substrate raws li lub teeb liab tus nqi tawm tswv yim los ntawm pyrometer thiab cov lus ntsuas kub.
