Yuav Ua Li Cas Thermocouples Kov Cov Kub Kub Kub Kub Kub Ua Haujlwm Li Cas?

Thermal shock yog ib qho teeb meem loj tshaj plaws rau cov kub khiav thermocouples, tshwm sim thaum kub hloov pauv sai sai thiab hnyav thaum pib, hloov khoom siv, lossis kev kaw thaum muaj xwm txheej ceev. Tsis zoo li kev sib tw ua kom sov, thermal poob siab cov ntsiab lus rau kev nthuav dav sai thiab kev cog lus uas tuaj yeem tawg sheaths, puas tsuaj rau hauv cov rwb thaiv tsev, tawg hlau junctions, thiab tsim cov teeb liab mus tas li. Nyob rau hauv cov txheej txheem kub khiav, thermal shock feem ntau tshwm sim thaum cov yas txias yog txhaj rau hauv lub taub hau preheated, lossis thaum lub tshuab kub txias txias sai. Qhov kev sib txuas ntawm qhov sib txuas, ua los ntawm ob qhov sib txawv ntawm cov hlau sib txawv, teb rau qhov kub thiab txias ntawm cov nqi sib txawv, tsim kom muaj kev ntxhov siab sab hauv uas tuaj yeem cuam tshuam cov vuam lossis ua rau micro- tawg. Mineral-insulated (MI) thermocouples yog cov tiv taus thermal shock ntau dua li cov yas-insulated hom vim hais tias cov compacted magnesium oxide core absorbs kev ntxhov siab thiab stabilizes cov xov hlau sab hauv. High- qib sheath cov ntaub ntawv xws li Inconel 600 kuj tiv taus qhov kub thiab txias hloov tau zoo dua li cov qauv stainless hlau. Cov thermocouples tsim tsis zoo feem ntau ua tsis tau tam sim ntawd tom qab kev kub ntxhov hnyav, uas qhia qhib circuits, luv circuits, los yog irreversible drift. Txhawm rau txo cov thermal shock puas, cov tuam txhab lag luam yuav tsum siv cov cua sov ua kom sov, tsis txhob cia txias, thiab xaiv cov shocks{12}}resistant MI- hom sensors. Cov neeg ua haujlwm yuav tsum tsis txhob tso cov tshuaj tiv thaiv txias rau hauv cov khoom kub kub los yog nthuav tawm cov ntsuas kub rau huab cua txias lossis noo noo. Txawm tias cov thermocouples ruaj khov tshaj plaws muaj kev txwv, yog li kev nkag siab txog tus cwj pwm thermal shock pab txuas ntxiv kev pab cuam lub neej thiab tiv thaiv kev ua tsis tiav. Thaum lub sij hawm, rov ua thermal poob siab maj mam degrades sensor kev ua tau zoo, ua calibration thiab hloov qhov tseem ceeb rau ntev -lub sij hawm stability.
