Raws li peb txhua tus paub, lub luag haujlwm tseem ceeb ntawm thermocouples yog ntsuas thiab tswj qhov kub thiab txias. Lawv tau siv dav hauv kev lag luam xws li petrochemical, tshuaj thiab kev tsim khoom. Hauv cov txheej txheem kev lag luam, kev ntsuas qhov kub thiab txias yog ze ze rau kev tswj xyuas cov khoom zoo thiab kev txhim kho cov txheej txheem. Yog li ntawd, platinum-rhodium thermocouple hlau yog ib qho kev xaiv zoo thiab raug ntawm ntau hom khoom.
Tab sis yog dab tsiplatinum-rhodium thermocouple hlau? Obviously, nws yog ib tug thermocouple uas muaj xws li ob precious hlau, platinum thiab rhodium, uas yog tshwj xeeb uas tsim los tiv taus kub kub thiab muab qhov tseeb ntsuas kub nyob rau hauv tej yam kev mob. Ob leeg hlau yog ua tib zoo xaiv rau lawv cov ntsiab lus melting siab, corrosion kuj thiab dav kub ntau yam. Feem ntau hom platinum-rhodium thermocouple hlau peb pom yog S-hom (platinum-10% rhodium / platinum) thiab R-hom (platinum-13% rhodium / platinum) thermocouples.
Platinum-rhodium thermocouple hlau muaj ob peb yam tseem ceeb. Ua ntej, platinum-rhodium thermocouple hlau tuaj yeem tiv taus qhov kub txog li 1600 ° C (2912 ° F), ua rau nws tsim nyog rau cov kev siv kub xws li kev kub kub, kev soj ntsuam lub cub tawg thiab kev tsim hluav taws xob. Qhov thib ob, kev sib xyaw ua ke ntawm platinum thiab rhodium hauv cov thermocouple xaim ua kom muaj kev ruaj ntseg zoo thiab rov ua dua ntawm qhov ntsuas kub, txawm tias nyob rau hauv kev ua haujlwm hnyav. Tsis tas li ntawd, platinum-rhodium thermocouple hlau kuj muaj zog corrosion kuj, nrog rau lub sij hawm teb ceev, thiab cov hlau tuaj yeem ua tiav qhov ntsuas kub ceev thiab raug, uas yog qhov tseem ceeb hauv kev lag luam kev lag luam.
Platinum-rhodium thermocouple hlau yog dav siv hauv kev lag luam nrog cov kev xav tau siab heev rau kev ntsuas kub thiab tswj. Piv txwv li, nyob rau hauv kev lag luam kev kho cua sov, platinum-rhodium thermocouple hlau yog siv los saib xyuas thiab tswj qhov kub ntawm qhov cub, qhov cub thiab cov txheej txheem kev kho cua sov kom ntseeg tau tias cov khoom yuav tsum tau ua tiav. Tsis tas li ntawd, kev lag luam aerospace cia siab rau platinum-rhodium hlau rau kev ntsuas qhov kub thiab txias thaum lub sij hawm tsim cov khoom siv dav hlau, cav qhov chaw thiab lwm yam khoom siv dav hlau tseem ceeb. Kev lag luam iav thiab ceramic siv nws los saib xyuas qhov kub ntawm cov kilns thiab furnaces siv hauv kev tsim cov iav, ceramics thiab cov ntaub ntawv refractory.
Hauv luv luv,platinum-rhodium thermocouple hlauyog ib qho cuab yeej tseem ceeb rau kev ntsuas qhov ntsuas kub kom raug thiab tswj tau nyob rau hauv high-temperature industrial field. Nws cov kev ua tau zoo heev, qhov kub thiab txias ntau thiab kev ntseeg tau ua rau nws yog thawj qhov kev xaiv rau kev lag luam nrog cov kev xav tau siab heev rau qhov raug thiab ruaj khov. Txawm hais tias koj koom nrog hauv kev kho cua sov, kev tsim hluav taws xob, kev lag luam petrochemical, lossis lwm yam kev lag luam uas xav tau kev ntsuas kub, platinum-rhodium thermocouple hlau muab qhov tseeb thiab ruaj khov uas yuav tsum tau ua kom ntseeg tau tias cov txheej txheem kev ua tau zoo thiab cov khoom zoo.
