Thermocouple raug raug txhais los ntawm cov qauv thoob ntiaj teb, tshwj xeeb tshaj yog IEC 60848, uas tsim ob chav kawm ua haujlwm siab: Chav 1 thiab Chav Kawm 2. Cov chav kawm no sawv cev rau qhov siab tshaj plaws kev ntsuas qhov yuam kev raws li tus qauv qauv, thiab lawv qhov sib txawv tsis yog tsuas yog cov txuj ci xwb - nws cuam tshuam ncaj qha rau ib feem zoo, kev ua tau zoo, kev tsim khoom, thiab kev tswj hwm tus nqi. Nkag siab txog cov chav kawm kam rau ua yog qhov tseem ceeb rau kev xaiv cov thermocouple kom raug rau ib daim ntawv thov.
Rau Hom K thermocouples, feem ntau siv hauv cov neeg khiav dej num kub, Chav Kawm 1 muaj qhov yuam kev ntau tshaj plaws ntawm ± 1.5℃ntawm 0℃thiab 1000 degree, thaum Class 2 tso cai rau qhov dav dav ntawm ± 2.5℃hauv tib qhov ntau. Ntawm qhov kub thiab txias ua haujlwm ntau dua hauv engineering polymer molding, cov kev zam no nthuav dav ntxiv, tsim kom muaj txiaj ntsig sib txawv hauv qhov tiag - tswj cov txheej txheem ntiaj teb. Thaum Chav Kawm 2 thermocouples tuaj yeem tshwm sim nyiaj txiag txaus siab vim lawv cov nqi qis dua, lawv qhov raug txo qis tsim cov nqi zais suav nrog cov nqi seem ntau dua, nce cov txheej txheem hloov kho, qhov tsis sib xws ntawm qhov ntev, thiab muaj kev pheej hmoo ntau dua ntawm qhov xwm txheej zoo.
Feem ntau -Lub hom phiaj molding nrog cov khoom siv resins xws li PP, PE, lossis PS, Chav Kawm 2 sensors yuav txaus, vim tias cov ntaub ntawv no muaj qhov ua haujlwm dav dua thiab tsis tshua muaj qhov kub thiab txias. Txawm li cas los xij, nyob rau hauv precision, technical, los yog tswj molding ib puag ncig-nrog rau cov khoom siv kho mob, cov khoom siv kho qhov muag, qhov chaw ruaj ntseg tsheb, cov khoom siv hluav taws xob, thiab cov khoom siv kho kom zoo nkauj pom kev zoo nkauj-Class 1 qhov tseeb yog tsis xaiv; nws yog qhov yuav tsum tau ua. Cov ntawv thov no yuav tsum muaj kev tswj xyuas nruj ntawm yaj viscosity, ntws tus cwj pwm, thiab cov khoom ruaj khov kom ua tau raws li qhov nruj me ntsis, pom, thiab kev ua haujlwm tshwj xeeb. Qhov kub tsis raug ntawm tsuas yog 2 degree, zoo nyob rau hauv qhov ntau ntawm Chav Kawm 2 thermocouple, tuaj yeem ua rau pom qhov tsis xws luag, vuam kab tsis muaj zog, ntim tsis txaus, lossis cov khoom siv degradation.
Tshaj li qhov ua tau zoo tam sim ntawd, thermocouple kam rau ua thiab qhov tseeb ua lub luag haujlwm tseem ceeb hauv kev ua raws cai. Kev lag luam xws li cov cuab yeej kho mob (ISO 13485), automotive (IATF 16949), thiab aerospace yuav tsum muaj tag nrho traceability ntawm cov txheej txheem tsis, nrog rau qhov kub thiab txias. Tsuas yog Chav Kawm 1 thermocouples uas siv tau, nce mus txog - txog - hnub tim daim ntawv pov thawj calibration muab cov kev ntsuas kev ncaj ncees uas yuav tsum tau rau kev tshuaj xyuas thiab ntawv pov thawj. Kev siv nyob rau hauv - cov ntsuas ntsuas siab nyob rau hauv cov haujlwm no tuaj yeem ua rau kev tshawb xyuas ua tsis tiav, cov neeg siv khoom tsis lees paub, lossis txawm tias raug cai raug cai yog tias tsis yog- cov khoom ua raws li nkag mus rau hauv cov khoom siv.
Ntev - lub sij hawm ruaj khov kuj tseem txuas nrog rau cov chav kawm kam rau ua. Thermocouples tsim los rau Chav Kawm 1 cov qauv siv ntau dua - cov khoom siv purity, kev tswj xyuas nruj dua, thiab kev sib txuas ntau dua. Yog li ntawd, lawv tuav lawv qhov tseeb ntev dua nyob rau hauv thermal cycling, siab -kub raug, thiab mechanical stress. Chav kawm 2 thermocouples zoo li drift sai dua, yuav tsum tau calibration ntau zaus lossis hloov.
Hauv cov ntsiab lus, kev xaiv ntawm Chav Kawm 1 thiab Chav Kawm 2 thermocouples tsis yog tus nqi xwb -txuag kev txiav txim siab. Nws yog ib qho kev xaiv zoo uas cuam tshuam rau qhov zoo, tawm los, kev ua raws, kev saib xyuas, thiab kev ua haujlwm ntev - tus nqi ua haujlwm. Rau ib qho molder hnyav txog qhov tseeb, kev ruaj ntseg, thiab kev tswj hwm kev nyab xeeb, Class 1 ntxhia-insulated thermocouples sawv cev rau qhov kev xaiv tiv thaiv nkaus xwb.
