Kev Tsim Kho thiab Siv Cov Thermocouple
Kev tsim kho ntawm hom galvanic thiab nws siv?
Thermocouple K hom (nickel-chromium-nickel-silicon) WRN series, N-hom (nickel-chromium-nickel-silicon-magnesium) WRM series, E-hom (nickel-chromium-tooj liab nickel) WRE series, J hom (hlau - WRF Series, T-type (tooj liab-tooj liab-nickel) WRC series, S-type (platinum thiab rhodium 10-platinum) WRP series, R hom (platinum thiab rhodium 13-platinum) WRQ series, B hom ( platinum rhodium 30-platinum rhodium 6) WRR series Tos.
① High precision measurement: thermocouple thiab cov khoom ntsuas tsis ncaj ncaj, tsis cuam tshuam los ntawm ob qhov kev tawm xov xwm.
③ kev ntsuas ntau: thermocouple los -40 ~ +600 ℃ tuaj yeem sov mus ntxiv.
1, qhov zoo ntawm thermocouple:
④ muaj zog muaj nuj nqi, zoo txhua yam muaj zog.
② lub sij hawm kub lub caij sov: thermocouple rau qhov hloov ntawm qhov kub hloov.
⑤ ntev lub neej, yooj yim rau nruab.
2, thermocouple ntau yam thiab qauv:
K-hom thermocouple yog lub ntsuas kub kub, uas hloov cov teeb liab kub rau hauv lub thermoelectromotive quab yuam teeb liab, los ntawm kev ntsuas hluav taws xob hauv nruab nrab ntsuas kub. Lub hauv paus ntsiab lus ntawm thermocouple kub ntsuas yog homogeneous conductor ntawm ob yam sib txawv los ua ib lub voj kev kaw, thaum qhov kub gradient ntawm ob hnub, lub Circuit Court yuav muaj ib qho tam sim no, ces ob hnub nrog Seebeck electromotive force - thermoelectromotive force, Uas yog qhov no hu ua Sebeck cov nyhuv. Ob tug sib txawv ntawm cov neeg ua haujlwm homogeneous rau cov kub electrode, qhov siab dua ntawm qhov kawg ntawm kev ua hauj lwm sab, qhov kawg ntawm qhov ntsuas kub yog dawb kawg, dawb kawg yog feem ntau ntawm qhov kub. Raws li thermoelectromotive quab yuam thiab kub raws li ib tug muaj nuj nqi ntawm kev sib cuag, ua thermocouple indexing table; indexing lub rooj yog dawb sov ntawm 0 ℃ nyob rau hauv cov kev mob ntawm poob ntawm txawv thermocouples nrog txawv rooj indexing. Nyob rau hauv thermocouple Circuit Court nkag tau rau peb cov ntaub ntawv hlau, tsuas yog ob tug neeg ntawm qhov kub ntawm qhov ntxeev lus, lub thermocouple tshwm sim thermoelectric zog yuav nyob tsis hloov, uas tsis yog qhov txuas hlau hluav taws xob hauv qhov cuam tshuam rau qhov feem Ib Vim li no, ntsuas kub thermocouple, nkag mus rau kev ntsuas cov ntsuas, ntsuas cov thermoelectromotive kev quab yuam, koj tuaj yeem paub qhov ntsuas qhov nruab nrab ntawm kev ntsuas.
