Kev ua tau zoo ntawm Platinum-Rhodium Thermocoumles

Platinum-Rhodium thermoco thermocouples tseem hu ua high-aws cov hlau uas muaj nuj nqis hlau thermocots. Platinum-Rhodium thermoco thermocouples tau muab faib ua ib qho platinum-rhodium-rhodium-rhodium-rhodium-rhodium-Rhodium-Rhodium-Rhodium-Rhodium 6). Raws li qhov ntsuas kub ntsuas sensors, lawv feem ntau yog siv nrog cov khoom siv kub thiab ntsuas thiab tswj cov roj ntsha thiab cov pa roj ntsha thiab cov roj av tsis pub dhau ntawm thaj tsam ntau lawm.
Platinum-Rhodium thermoco thermocouples yog ua los ntawm ob tug neeg ntawm cov sib txawv sib txuas ntawm ob qho kawg los ua lub voj. Thaum lub ntsuas kub ntawm ob lub junctions muaj sib txawv, ib lub thermal tam sim no yuav tsim tawm hauv lub voj. Yog tias muaj qhov sib txawv kub ntawm qhov ua haujlwm kawg thiab qhov kawg ntawm thermocouple, cov zaub cov peev txheej yuav qhia tau tias muaj txiaj ntsig kub kom sib haum los ntawm thermocouple. Lub thermoelectric kub ntawm lub platinum-rhodium thermocouple yuav nce raws li qhov ntsuas kub nce ntxiv. Nws loj yog tsuas cuam tshuam nrog cov khoom thermocouple thiab ntsuas kub ntawm ob xaus, thiab tsis muaj dab tsi ua rau qhov ntev thiab txoj kab uas hla ntawm thermoelectrode. Cov tsos ntawm ntau platinum-Rhodium thermocouples feem ntau yog qhov sib txawv vim yog qhov xav tau, tab sis lawv cov qauv yooj yim, yog suav nrog lub tes tsho tiv thaiv lub raj thiab hlws ris tsho tiv thaiv lub thawv.
Cov txiaj ntsig zoo: Platinum-Rhodium thermocoumles muaj qhov zoo tshaj plaws, kev ntsuas kub nyob ntev thiab cov ntsuas kub siab thiab huab cua siab. Nws yog qhov haum rau oxidizing thiab inert atmospheres, thiab tseem siv tau rau lub tshuab nqus tsev rau lub sijhawm luv luv, tab sis tsis yog rau kev txo cov cua nab kuab lossis cov cua sov uas muaj cov hlau lossis tsis yog xim hlau. Ib qho txiaj ntsig pom tseeb ntawm hom b thermohou yog tias lawv tsis tas yuav them nyiaj los ntawm kev them nyiaj xov hlau, vim hais tias lub peev xwm thermoelectric muaj peev xwm tsawg dua 3μv nyob rau hauv thaj tsam ntawm {3}} ~ 50 degree.
