Yuav ua li cas xaiv Txoj Cai Thermocohople Khoom Siv los txo cov thermal inertia ntawm thermocouple?

Txhawm rau xaiv cov khoom siv thermocouple tsim nyog los txo cov thermal inertivity, nws yog qhov tsim nyog los ua kom sov, nws yog cov ntsuas cua sov, tshuaj lom neeg ruaj khov thiab tus nqi ntawm cov khoom siv. Cov hauv qab no yog qhov kev tshawb fawb tshwj xeeb:
Siab thermal conductivity: cov ntaub ntawv nrog hi thermal conductivity tuaj yeem ua sai sai ua kom sai li kub, cia cov thermocouple los teb rau qhov kub hloov pauv sai dua. Piv txwv li, cov thermal conductivity ntawm tungsten-rhoy alloy yog tus siab. Hauv kev ntsuas kub siab, siv tungsten-rhoy alloy ua ib qho khoom siv thermocouple muaj peev xwm txo cov thermal inertia thiab ntsuas kub sai thiab raug.
Tsawg qhov cua sov tshwj xeeb: thaum cov ntaub ntawv nrog cov kub me me nqus tib lub cua sov, qhov kub thiab txias dua, uas yog qhov ua kom txo thermal inertia. Piv txwv li, cov lus sov tshwj xeeb ntawm platinum-rhodium alloy yog me me. Hauv kev ntsuas kub siab, nws tuaj yeem ua raws li qhov ntsuas kub hloov pauv, txhim kho lub sijhawm thiab qhov tseeb ntawm kev ntsuas.
Qhov tsim nyog ua kom haum kub: Cov coefficent kub yuav tsum muaj qhov kub thiab txias, yog li thaum qhov ntsuas kub hloov pauv, uas yooj yim rau kev ntsuas thiab kev tswj hwm. Piv txwv li, cov kev ua kom sov coefficient ntawm Nickel-Chromium-Npib-Silicon Thermocouple kub nyob rau hauv qhov dav dav, thiab muaj me me thermal inertia.
Cov tshuaj ruaj khov zoo: cov khoom yuav tsum muaj cov tshuaj ruaj khov xws li oxidation thiab corrosion nyob rau hauv qhov ntsuas kev ntsuas kom ntseeg tau thiab kev pabcuam lub neej ntawm thermocouple. Piv txwv li, hauv ib puag ncig nrog cov roj corrosive, xaiv ib qho khoom siv thorkocouple los ntawm kev ua kom huv si los ntawm kev ua kom huv si tuaj yeem teb rau qhov ntsuas kub hloov pauv thiab sai.
Tus nqi tau zoo: nyob rau hauv lub rooj sib tham ntawm lub rooj sib tham ua tau zoo, tus nqi ntawm cov khoom yuav tsum tau txiav txim siab. Piv txwv li, txawm hais tias cov ntaub ntawv hlau muaj nqis xws li platinum alloys muaj qhov ua tau zoo, lawv feem ntau siv nyob rau hauv cov sijhawm uas ntsuas tau muaj peev xwm tsawg; Thaum cov ntaub ntawv xws li Nickel-Chromium-Npib-Silicon yog qhov pheej yig thiab tau siv dav hauv kev lag luam kub zoo.
Ib qho ntxiv, hauv cov ntawv thov siv, cov khoom thermocouple yuav tsum tau xaiv raws li kev ntsuas ib puag ncig, qhov ntsuas qhov ntsuas tau thiab lwm yam. Piv txwv li, hauv qhov chaw tsawg-ib puag ncig, tooj-constantan thermocoumles muaj ntau dua, nrog me me thermal inertia thiab tuaj yeem ntsuas qhov ntsuas qis; Nyob rau hauv kev kub-ib puag ncig, cov ntaub ntawv xws li tungsten-rhoy alloys uas tiv taus kub thiab muaj tsawg thermal inertia tuaj yeem xaiv.
