Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm platinum thiab rhodium thermocouple piv rau cov thermocouple zoo tib yam?
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm platinum thiab rhodium thermocouple piv rau cov thermocouple zoo tib yam?
Kev hais lus ntawm platinum thiab rhodium thermocouple yuav muaj ntau ntawm cov neeg tsis paub nws yog dab tsi, peb muaj kev nkag siab txog thermocouple, tiam sis platinum thiab rhodium thermocouple neeg tsis paub dab tsi cov yam ntxwv, qhov tseeb, platinum thiab rhodium yog ib qho precious hlau, thiab platinum thiab rhodium thermocouple yog ua los ntawm platinum thiab rhodium, nram qab no peb tuaj ua ke kom paub txog nws
Platinum-rhodium thermocouple, tseem hu ua kub kub thermocouple, platinum thiab rhodium muaj ib lub platinum thiab rhodium (platinum rhodium 10 platinum thiab rhodium) thiab ob platinum thiab rhodium (platinum thiab rhodium 30-platinum rhodium 6) ntsiab lus, lawv siv los ua qhov ntsuas kub, Transmitter, tus saib xyuas thiab cov khoom ntsuas, thiab lwm yam, los tsim cov txheej txheem tswj kev tswj ncaj qha los sis kev tswj cov txheej txheem ntau yam hauv cov ntau ntawm 0- 1800 ℃, dej thiab roj nruab thiab .
Platinum thiab rhodium thermocouple yog tsim ntawm ob qhov sib txawv ntawm tus neeg xyuas pib ntawm ob hnub ntawm qhov Circuit Court rau hauv lub voj, thaum ob qhov sib txig ntawm ob qhov sib txawv, nws yuav ua kom kub hauv qhov Circuit Court. Yog tias muaj qhov sib txawv ntawm kev ua hauj lwm kawg ntawm lub thermocouple thiab qhov kawg, daim duab ntsuas yuav qhia tau tias qhov ntsuas kub sib haum rau qhov thermoelectric peev xwm tau tsim los ntawm lub thermocouple. Lub thermoelectric tshav kub ntawm lub platinum thiab rhodium thermocouple yuav nce nrog qhov nce ntawm qhov kub ntawm qhov ntsuas kawg. Qhov luaj li cas tsuas yog ntsig txog qhov kub ntawm cov thermocouple khoom thiab ob qho tag nrho, tsis hais qhov ntev thiab txoj kab uas hla hluav taws xob kub. Cov tsos ntawm platinum thiab rhodium thermocouples feem ntau txawv heev vim qhov kev xav tau, tab sis lawv cov qauv yooj yim yog roughly tib yam, feem ntau yog los ntawm thermal electrode, thaiv kev tiv thaiv thaiv tes thiab qhov nruab nrab kem thiab lwm yam loj yam.
Zoo: Platinum thiab rhodium thermocouple nyob rau hauv lub thermocouple series nrog siab tshaj plaws, qhov zoo tshaj plaws stability, kub ntau, ntev lub neej, high kub qis txwv zoo. Haum siv nyob rau hauv oxidizing thiab inert atmospheres, tab sis kuj siv sij hawm luv luv nyob hauv lub tshuab nqus tsev, tab sis tsis nyob rau hauv ib qho chaw cua los yog hauv cov cua los yog hlau tsis sib haum xeeb. Ib qho tseem ceeb ntawm hom B thermocouple yog qhov nyiaj uas tsis yog yuav tsum tau ua nrog compensating ua vim tias thermoelectric zog tsawg dua 3μV ntawm qhov ntau ntawm 0 txog 50 ° C.
Disadvantages: Platinum thiab rhodium thermocouple tsis muaj thermoelectric fais fab tuag yog me me, tsis tshua muaj siab, kev kho siab kub siab, hlau kim tsho, thiab yog li kev siv nyiaj ib zaug. Platinum thiab rhodium thermocouple yog tsim ntawm ob yam sib txawv ntawm tus neeg xyuas pib ntawm ob hnub ntawm qhov Circuit Court rau hauv lub voj, thaum ob qhov sib hloov ntawm ob qhov sib txawv, nws yuav ua kom kub hauv lub voj. Yog tias muaj qhov sib txawv ntawm kev ua hauj lwm kawg ntawm lub thermocouple thiab qhov kawg, daim duab ntsuas yuav qhia tau tias qhov ntsuas kub sib haum rau qhov thermoelectric peev xwm tau tsim los ntawm lub thermocouple.
