Kev Ntsuas Cov Qauv Ntawm Cov Roj Thermocouple

Lub sijhawm teb ntawm cov roj cuathermocoupleyog nyuaj nyuaj. Cov kev sim sim sib txawv muaj cov qhab nia sib txawv ntawm cov cua sov thiab lub sijhawm sib txawv, thiab lub sijhawm tshav kub yog luv. Txhawm rau ua kom lub sijhawm thermal teb, lub teb chaws qauv, lub sijhawm teb chaws: Lub sijhawm teb thermal yuav tsum tau nqa tawm ntawm cov dej uas tshwj xeeb ntws. Cov dej ntws ntws ntawm lub cuab yeej yuav tsum tau tswj hwm los ntawm 0.4 ± 0.05 m / s, thiab qhov kub thiab txias hloov chaw, thiab kub hloov chaw, thiab kub hloov mus ± 1% ntawm qhov kub elongation. Qhov tob tob ntawm kev sim thermocouple yog 150 hli lossis cov tsim kev tsim (xaiv ib qho nqi me me thiab qhia hauv daim ntawv qhia xeem).
Vim tias cov cuab yeej no muaj ntau yam nyuaj, tsuas yog ob peb lub chaw tsim khoom siv, yog li cov qauv hauv tebchaws tau muab siv, tab sis cov ntaub ntawv yuav tsum tau qhia.
Txij li cov thermocoes hauv t-homthermocoupleyog me me ze chav sov, lub sijhawm teb kub tsis yooj yim rau kev ntsuas, yog li lub teb chaws txheem sib dhos ntawm S-hom thermocouple ntawm tib cov lus tshwj xeeb, thiab tom qab ntawv sim.

Thaum qhov kev ntsuas, cov zis ntawm Thermocouple yuav tsum tau sau rau lub sijhawm T0.5 sib haum rau lub sijhawm ntsuas kub T0.1 thiab yog qhov ntsuas kub ntawm 90% ntawm cov lus teb cua sov T0.9. Lub sijhawm thermal teb tau sau tseg yuav tsum yog tus nqi nruab nrab ntawm tsawg kawg peb qhov kev ntsuas. Txhua qhov ntsuas tau ua rau yuav tsum yog li ntawm ± 10% ntawm kev sib txawv ntawm qhov nruab nrab. Tsis tas li ntawd, lub sijhawm yuav tsum tau ua qhov ntsuas kub hloov chaw yuav tsum tsis pub tshaj ib feem kaum ntawm T0.5 ntawm kev sim thermocouple. Teev lub sijhawm teb ntawm lub ntsuas lossis twj paj nruag yuav tsum tsis pub tshaj ib feem kaum ntawm T0.5 ntawm kev simthermocouple.
