Raws li peb txhua tus paub, lub luag haujlwm tseem ceeb ntawm cov thermocouples yog ntsuas thiab tswj qhov kub. Lawv siv dav hauv kev lag luam xws li petrochemical, tshuaj thiab kev tsim khoom. Hauv cov txheej txheem kev lag luam, kev saib xyuas qhov kub thiab txias kom raug yog qhov cuam tshuam nrog kev tswj xyuas cov khoom zoo thiab kev txhim kho cov txheej txheem ua haujlwm zoo. Yog li ntawd, platinum-rhodium thermocouple hlau yog qhov kev xaiv txhim khu kev qha thiab raug ntawm ntau hom khoom.
Tiam sis yog dab tsiplatinum-rhodium thermocouple hlauNws yog ib lub thermocouple uas muaj ob hom hlau muaj nqis, platinum thiab rhodium, uas tau tsim tshwj xeeb los tiv taus qhov kub siab thiab muab kev ntsuas kub kom raug hauv qab qhov xwm txheej hnyav. Ob hom hlau no tau xaiv zoo rau lawv cov ntsiab lus yaj siab, tiv taus corrosion thiab ntau qhov kub thiab txias. Cov hom hlau thermocouple platinum-rhodium feem ntau uas peb pom yog S-hom (platinum-10% rhodium/platinum) thiab R-hom (platinum-13% rhodium/platinum) thermocouples.
Hlau thermocouple Platinum-rhodium muaj ntau yam ntxwv tseem ceeb. Ua ntej, hlau thermocouple platinum-rhodium tuaj yeem tiv taus qhov kub txog li 1600 ° C (2912 ° F), ua rau nws tsim nyog rau cov ntawv thov kub xws li kev ua haujlwm kub, kev saib xyuas lub cub tawg thiab kev tsim khoom siv hauv aerospace. Qhov thib ob, kev sib xyaw ua ke ntawm platinum thiab rhodium hauv hlau thermocouple ua kom muaj kev ruaj khov zoo heev thiab rov ua dua ntawm kev ntsuas kub, txawm tias nyob rau hauv cov xwm txheej ua haujlwm hnyav. Tsis tas li ntawd, hlau thermocouple platinum-rhodium kuj muaj kev tiv thaiv corrosion muaj zog, nrog rau lub sijhawm teb sai, thiab hlau tuaj yeem ua tiav kev ntsuas kub sai thiab raug, uas yog qhov tseem ceeb hauv cov txheej txheem kev lag luam dynamic.
Cov hlau thermocouple platinum-rhodium yog siv dav hauv cov teb kev lag luam uas muaj qhov yuav tsum tau ntsuas thiab tswj qhov kub siab heev. Piv txwv li, hauv kev lag luam kho cua sov, cov hlau thermocouple platinum-rhodium yog siv los saib xyuas thiab tswj qhov kub ntawm cov cub tawg, qhov cub thiab cov txheej txheem kho cua sov kom ntseeg tau tias cov khoom siv xav tau tau ua tiav. Tsis tas li ntawd, kev lag luam aerospace vam khom cov hlau platinum-rhodium rau kev saib xyuas qhov kub thiab txias thaum lub sijhawm tsim cov khoom siv dav hlau, cov khoom siv cav thiab lwm yam khoom siv aerospace tseem ceeb. Kev lag luam tsim iav thiab ceramic siv nws los saib xyuas qhov kub ntawm cov kilns thiab cov cub tawg siv hauv kev tsim cov khoom siv iav, ceramics thiab cov ntaub ntawv refractory.
Hauv luv luv,platinum-rhodium thermocouple hlauyog ib qho cuab yeej tseem ceeb rau kev ntsuas qhov kub thiab txias kom raug thiab tswj tau hauv kev lag luam kub siab. Nws qhov kev ua tau zoo heev, qhov kub thiab txias dav thiab kev ntseeg siab ua rau nws yog thawj qhov kev xaiv rau cov lag luam uas muaj qhov xav tau siab heev rau qhov tseeb thiab ruaj khov. Txawm hais tias koj koom nrog kev kho cua sov, kev tsim khoom siv dav hlau, kev ua cov khoom siv roj av, lossis lwm yam lag luam uas xav tau kev ntsuas kub siab, platinum-rhodium thermocouple hlau muab qhov tseeb thiab ruaj khov uas xav tau los xyuas kom meej tias cov txheej txheem ua tau zoo tshaj plaws thiab cov khoom zoo.
