Kev Siv Platinum Sheaths Li Cas Txhim Kho Qhov Zoo ntawm Thermocouples hauv Precision Measurements?

Platinum sheaths muab cov tshuaj lom neeg ntau dhau. Nyob rau hauv precision dimension cov kev pab cuam, nws yog ib qho tseem ceeb heev uas yuav tsum muaj ib tug sheath ntaub uas tsis hnov ​​mob nrog lub encircling ib puag ncig. Platinum yog qhov tshwj xeeb pov thawj tiv thaiv corrosion thiab tshuaj tua kab mob, xyuas kom meej tias cov thermocouple nyob twj ywm tsis cuam tshuam nrog kev pab ntawm kev siv cov kab mob. Qhov kev sib npaug no ua kom yooj yim kom qhov tseeb ntawm qhov ntsuas kub ntawm lub sijhawm.
Lawv muaj cov thermal conductivity zoo heev. Platinum yog qhov zoo tshaj plaws ntawm kev ua kom sov, uas tso cai rau kev hloov pauv ntsuab ntawm qhov sov sov los ntawm ib puag ncig mus rau qhov sib txuas ntawm thermocouple. Qhov no tshwm sim nyob rau hauv lub sij hawm tshwm sim sai dua thiab zoo dua qhov ntsuas kub. Nyob rau hauv cov kev pab cuam precision nyob rau hauv uas txawm me me qhov kub hloov pauv xav kom kuaj tau sai, cov thermal conductivity ntau dhau ntawm platinum sheaths yog qhov zoo dua.
Platinum sheaths muab cov thermal o zoo ib yam. Hauv cov thermocouples, qhov sib txawv ntawm thermal o ntawm cov sheath thiab cov thermocouple xov hlau tuaj yeem ua yuam kev hauv kev ntsuas kub. Platinum muaj qhov tsawg kawg nkaus thiab qhov ntsuas qhov ntsuas qhov ntsuas qhov loj, uas txo qis qhov ua yuam kev. Qhov no tau lees tias lub thermocouple ua haujlwm ib txwm thiab raug thoob plaws qhov kub ntau yam.
Lawv yog cov tseem ceeb heev. Kev ntsuas Precision feem ntau xav tau cov thermocouples uas yuav ntsib kev rov siv dua thiab qhov chaw phem. Platinum yog cov ntaub uas muaj zog thiab ruaj khov uas tuaj yeem tiv taus kev ntxhov siab, kev puas tsuaj, thiab kev cuam tshuam. Qhov kev ruaj khov no ua kom yooj yim kom paub tseeb tias cov thermocouple nyob hauv qhov xwm txheej zoo thiab tswj xyuas kom muaj kev ntsuas raug nyob rau lub sijhawm ntev.
