Txoj cai yooj yim ntawm thermocouple
Ntawm no qhia rau koj txog txoj cai yooj yim ntawm thermocouple? Nyob rau hauv cov ntaub ntawv ntawm
Lub thermoelectric hwj chim ntawm lub thermocouple nyob ntawm qhov kub ntawm lub thermocouple thiab qhov kub ntawm ob txoj hlua, ywj siab ntawm qhov kub raws qhov faib rau cov kub electrode thiab cov duab ntawm lub thermal electrode, uas yog kev cai lij choj kub.
Lub thermocouple Circuit Court, thermocouple circuit ua rau tag nrho thermal muaj peev xwm sib npaug rau cov thermocouple ntawm T, Tn thaum lub thermoelectric Eab (T, Tn) thiab tib thermocouple hauv (Tn, To) Lub thermocouple Circuit, algebraic sum ntawm lub thermoelectric tsim tau Eab (Tn.To).
Siv cov mis li Eab (T, nTo) = Eab (T, To) + Eab (Tn, To) Cov kev cai kub ntawm nruab nrab yog lub hauv paus rau kev tsim cov thermocouple indexing. Raws li txoj cai lij choj ntawm nruab nrab kub cev, tsuas yog qhov txias txias ntawm 0 ℃ thaum ntsuas kub thiab thermal tej zaum ntawm lub rooj (sub-rooj), thaum lub qhov txias txias tsis yog 0 ℃, thermoelectric zog los ntawm lub mis
Tus neeg xyuas theem nrab Kev ntsuas kub thermocouple kub ntsuas yuav tsum tau nkag tau rau hauv lub voj ntsuas ntawm xov hlau thiab cov twj paj nruag (xws li cov amplifiers, millivolt, thiab lwm yam). Thaum cov hlau lead thiab instrumentation, yuav tsis cuam tshuam rau lub zog thermoelectric nws? Tus neeg tswj xyuas cov theem pib qhia tau hais tias nyob hauv thermocouple Circuit Court, yog tias ntev li ntawm kev nkag ntawm tus neeg zaum thib peb ntawm ob qho tib si ntawm tib qhov kev ntsuas kub, tag nrho thermal tej zaum ntawm Circuit Court tau tsis muaj dab tsi.
