Yuav ua li cas kom ntseeg tau qhov tseeb ntawm qhov ntsuas kub ntawm qhov ntsuas kub tsis tshua muaj siab?

Nyob rau hauv ib puag ncig uas tsis tshua muaj kub, qhov ntsuas kub zoo yog qhov tseem ceeb rau ntau yam kev pab cuam ua ke nrog cov kev tshawb fawb cryogenic thiab cov txheej txheem lag luam. Muaj ntau ntau yam uas yuav tsum nco ntsoov kom paub tseeb tias qhov ntsuas kub zoo.
Thermocouples tuaj yeem siv rau qhov ntsuas qhov ntsuas kub hauv qhov kub tsis tshua muaj siab. Ib qho tseem ceeb tivthaiv yog xaiv cov khoom siv thermocouple haum. Tshwj xeeb thermocouple alloys yog tsim los ua haujlwm ntawm qhov kub thiab txias thiab khaws lawv qhov tseeb. Piv txwv li, zoo ntau yam ntawm tooj liab-constantan thermocouples yog tsim nyog rau cov kev pab cuam uas tsis muaj kub.
Lwm qhov kev saib xyuas yog qhov rwb thaiv tsev thiab kev nyab xeeb ntawm cov thermocouple. Nyob rau hauv qhov kub tsis tshua muaj siab, condensation thiab icing tuaj yeem tshwm sim, uas tuaj yeem cuam tshuam rau qhov tseeb ntawm qhov ntev. Kev rwb thaiv tsev tsim nyog thiab kev tiv thaiv tuaj yeem txuag koj cov dej noo thiab cov kab mob sib txawv los ntawm kev ua tiav cov thermocouple thiab ua kom ntseeg tau tias kev nyeem ntawv.
Calibration kuj tseem ceeb heev rau qhov tseeb qhov kub thiab txias. Thermocouples yuav tsum tau calibrated nyob rau hauv qis kub kom account rau tej deviations los yog tsis raug. Qhov no tuaj yeem ua tiav qhov kev siv cov kev cai siv los yog calibration da dej tshwj xeeb uas tsim los rau cov kev pab cuam kub qis.
Kev teeb tsa ntawm lub thermocouple kuj tuaj yeem cuam tshuam nws qhov tseeb. Kev tso kawm kom raug thiab kho ntawm cov thermocouple nyob rau hauv qhov chaw nyob ib puag ncig yog qhov tseem ceeb kom paub tseeb tias qhov kev xav tau thermal kov thiab txwv kev hloov pauv qhov tsis raug. Tsis txhob muaj kev sib tsoo thiab kev vibration ntawm lub thermocouple kuj tuaj yeem pab khaws nws qhov tseeb.
