Raws li kev tsom mus rau yav dhau los ntawm qhov yuav tsum tau ua kom raug qhov tseeb ntawm kev kho kub khiav thermocouples raws li cov txheej txheem txheej txheem, cov teeb meem tshwm sim hauv cov txheej txheem pov thawj no yog raws li hauv qab no:
Ib puag ncig siv tsis raug: Cov dej khov tsis txaus hauv cov dej khov - dej sib tov, tsis muaj lub thawv rwb thaiv tsev, thiab kev nkag mus sai ntawm cov cua sov hauv ib puag ncig ua rau qhov ntsuas kub ntawm qhov sib txawv ntawm 0 degree, ncaj qha ua rau muaj qhov sib txawv ntawm qhov kev pov thawj.
Kev Txhim Kho Tsis Zoo: Thermocouple sojntsuam tsis tag rau hauv dej khov -dej interface, kov lub thawv ntim phab ntsa, lossis ncaj qha tiv tauj cov dej khov tiv thaiv kom tsis txhob hnov qab qhov ntsuas kub ntawm 0 degree, ua rau muaj kev hloov pauv hauv kev nyeem ntawv.
Cold Junction Compensation Failure: Ib qho malfunction nyob rau hauv lub txias junction them nyiaj module ntawm qhov kub thiab txias tswj system tsis ua hauj lwm cuam tshuam ntawm chav tsev kub ntawm qhov ntsuas kub. Txawm hais tias lub thermocouple nws tus kheej yog qhov tseeb, qhov kawg tso tawm tus nqi tseem yuav pom qhov sib txawv tseem ceeb.
Cov Txheej Txheem Kev Ua Haujlwm Saib Xyuas: Lub sijhawm tsis txaus, kev nyeem ntawv ntxov ua ntej qhov kub thiab txias yog qhov ruaj khov, thiab kev ua haujlwm tsis zoo thaum lub sijhawm rov ua pov thawj ua rau cov ntaub ntawv pov thawj tsis zoo.
Tus qauv ntsuas tsis muaj traceability. Cov phom kub siv rau kev sib piv tsis yog nyob rau hauv nws lub sij hawm metrological validity thiab inherently muaj qhov raug yuam kev, ncaj qha rendering tag nrho cov ntaub ntawv pov thawj tsis muaj nqis.
Cov teeb meem no cuam tshuam ncaj qha rau qhov ntsuas qhov ntsuas qhov ntsuas qhov tseeb thiab yooj yim ua rau kev txiav txim tsis raug ntawm qhov tseeb qhov tseeb ntawm cov thermocouple.
