Yuav Ua Li Cas Thermocouples Hloov Kho rau Kev Siv Hauv Chaw Ua Haujlwm Siab?

Ib txoj hauv kev yog siv cov tshuaj uas tuaj yeem ntsib mus rau qhov qis qis thiab qhov kub thiab txias uas tau pom nyob rau qhov siab tshaj. Tshwj xeeb alloys los yog ceramics nrog txoj cai thermal tshuav nyiaj li cas thiab txhua yam hluav taws xob yuav raug txiav txim siab rau kev tsim kho thermocouple. Piv txwv li, paub tseeb tias cov hlau refractory tuaj yeem dhau qhov xwm txheej nyuaj thiab muab qhov ntsuas kub kom raug. Nyob rau hauv qhov chaw siab tshaj qhov kev tshawb fawb qhov chaw, ib lub thermocouple tsim los ntawm cov hlau uas tsim nyog tuaj yeem ua kom pom qhov ntsuas kub ntawm gadget uncovered rau cov tawv nqaij thiab tsis muaj ntshav.
Lwm qhov kev hloov kho yog los kho cov rwb thaiv tsev ntawm cov thermocouple. Ntawm qhov siab tshaj, tej zaum yuav muaj kev phom sij ntxiv ntawm kev cuam tshuam hluav taws xob thiab kev rwb thaiv tsev vim tias huab cua tsis zoo. Siv cov tshuaj tiv thaiv zoo heev thiab kev tiv thaiv zoo tuaj yeem pab tiv thaiv cov thermocouple los ntawm cov hluav taws xob sab nraud. Piv txwv li, nyob rau hauv ib lub dav hlau khiav ntawm qhov siab tshaj plaws, lub thermocouple nrog cov rwb thaiv tsev zoo dua tuaj yeem ua rau qee qhov kev ntsuas kub siab rau kev saib xyuas lub cav.
Thermocouples kuj tuaj yeem tsim nrog cov ntim tshwj xeeb lossis cov ntaub thaiv npog los tiv thaiv lawv ntawm lub cev kev ntxhov siab ntawm qhov chaw siab tshaj qhov chaw. Qhov no tej zaum yuav xav kom muaj kev poob siab-resistant casings los yog khoov mounts uas tuaj yeem ua raws li kev vibrations thiab kev ua haujlwm ntawm qhov siab tshaj. Piv txwv li, nyob rau hauv lub satellite TV rau pc los yog cheeb tsam sojntsuam, ib tug ceev faj ntim cov thermocouple tuaj yeem ntsib qhov kev tso tawm vibrations thiab cov xwm txheej hnyav ntawm cheeb tsam.
Calibration rau kev siv ntau tshaj qhov siab yog qhov tseem ceeb. Tag nrho cov kev ua tau zoo ntawm cov thermocouples tuaj yeem muab tso rau hauv qis qis nrog qhov txo qis thiab qhov tshwj xeeb thermal nyob ntawm qhov siab tshaj. Cov txheej txheem calibration tshwj xeeb thiab gadget yuav raug siv los ua qee qhov ntsuas kub kom raug. Piv txwv li, ib lub thermocouple yuav tsum tau siv nyob rau hauv qhov siab tshaj plaws huab cua balloon kuj yuav xav kom calibrated hauv qab simulated ntau-qhov siab qhov xwm txheej kom paub tseeb tias nws qhov tseeb.
