Yuav ua li cas siv Platinum rhodium thermocouples kom raug?

Yuav ua li cas yog qhov kev raug txim yog tias cov hlau hlau tuaj rau hauv huab cua? Firstly, peb yuav tsum tau muab cov lus qhia luv luv rau thermocouples. Thermocouples yog qhov tseeb kub sensing ntsiab thiab seev. Nws ntsuas ncaj qha kub thiab hloov cov teeb liab kub rau hauv qhov kub thiab txias ntawm cov twj ntsuas hluav taws xob (theem nrab seev). Thermocoples, raws li ntsuas cov cuab yeej rau thermal saib xyuas thiab kuaj, ua lub luag haujlwm tseem ceeb hauv kev siv.

Hauv cov txheej txheem tam sim no, nrhiav kev siv tshuab thiab nws cov cuab yeej ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv cov khoom tsis muaj kev puas tsuaj, ntsuas thiab metrology ntawm ntau yam khoom thiab cov khoom siv. Ceramic thermocuples ua lub luag haujlwm tsis tseem ceeb hauv kev txhim kho qhov zoo thiab kev lag luam muaj txiaj ntsig ntawm cov lag luam.
Tus txheej txheem ua hauj lwm ntawm thermocouple yog thaum ob qho kev sib txawv tau txuas rau hauv Circuit Court, lub peev xwm thermoelectric sib txawv yog qhov kub ntawm ob lub taub hau sib txawv. Yog tias muaj qhov sib txawv kub ntawm qhov ntsuas tau xaus ntawm thermocouple (kawg ntawm kev ntsuas kub yog hu ua ntsuas qhov ntsuas kub tau ua rau lub peev xwm ntsuas kub ua ke rau lub peev xwm thermoelectric uas yog thermocouple.

Platinum Rhodium thermocouple yog ib txwm ntsuas sov ntsuas kub thiab cov khoom siv oxidation ruaj khov, haum rau kev siv txuas ntxiv mus hauv oxidizing thiab inert atmospheres. Lub sijhawm siv ntev ntev yog 1600 degree, thiab lub sijhawm luv siv kub yog 1800 degree.
Cov txiaj ntsig zoo ntawm Platinum Rhodium Throdoco Thermoco

Platinum Rhodium thermoco thermocots muaj qhov zoo ntawm kev ntsuas, ntsuas dav ntau, thiab ntsuas kub ntev ntev hauv cov kev txwv sab sauv hauv cov thermocouple koob. Haum rau oxidizing thiab inert atmospheres, thiab kuj tseem siv tau rau lub tshuab nqus tsev rau lub sijhawm luv luv, tab sis tsis haum rau kev txo cov cua nab kuab lossis cov cua sov uas muaj cov hlau tsis sib xws. Ib qho txiaj ntsig tseem ceeb ntawm B-ntaus thermocouples yog tias lawv tsis tas yuav tsum them nyiaj, raws li lub peev xwm them nyiaj tsawg dua 3 μ {3}} degree.

Qhov tsis zoo ntawm Platinum Rhodium thermoco thermoco

Tus shortcomed yog thermoelectric peev xwm, tsawg rhiab dhuav kev nyeem ntawv, muaj cov khoom siv hlau qis, thiab yog li ntawd kev nqis peev hlau loj, thiab yog li ntawd kev nqis peev hlau loj, thiab yog li ntawd kev nqis peev ntau. Tus qauv ua hauj lwm ntawm Platinum Rhodium Rhodium Thermocohople yog qhov sib xyaw ua ke yog txuas rau hauv Circuit Court yog qhov ntsuas kub ntawm ob lub taub hau sib txawv. 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.

Daim ntawv thov ntau yam ntawm Platinum Rhodium throdium thermocouple

Platinum rhodium thermocouple yog qhov tseeb uas siv cov yam ntxwv kub uas nws tau hloov kho qhov ntsuas kub thaum nruab nrab yog qhov ntsuas kub nyob rau hauv nruab nrab qhov ntsuas kub nyob. Lub transmitter yog tsuas yog siv nyob rau hauv cov liaj teb xws li petrochemicals, metallurging, thiab qib siab, interface, thiab ntom ntawm cov kua. Thaum siv nrog cov khoom siv throttling, nws tuaj yeem siv los ntsuas tus nqi txaus. Nws hloov cov teeb liab ntsuas rau hauv 4-20 Madc thiab kis tau nws, uas tuaj yeem tsim ntau tus kheej tswj cov tshuab.

Xaiv Cov Platinum Rhodium Thermoco Thermoco

Thaum ntsuas ntsuas kub yog ib txwm nyob nruab nrab ntawm 1000 ~ 1300 degree, nws raug nquahu kom siv ib tus platinum rhodium recocouple (platinum rhodium 10 platinum). Thaum ntsuas kub yog ib txwm nyob nruab nrab ntawm 1200 ~ 1600 Qib, nws raug nquahu kom siv cov platinum rhodium ribocouple (platinum rhodium 6). Qhov no ua kom cov kev pabcuam lub neej ntawm cov platinum rhodium throdium thermocouple nyob rau hauv qhov kub thiab txias siv.

Lub thermoelectric muaj peev xwm ntawm thermocouple yuav nce raws li qhov ntsuas kub ntawm kev ntsuas maj mam nce. Qhov ntau ntawm thermoelectric muaj peev xwm tsuas yog cuam tshuam nrog cov khoom ntawm cov thermocouple tus neeg xyuas thiab qhov kub thiab muaj kev ywj pheej thiab cov taub ntawm cov thermoelectric electrode.

Kev siv hluav taws xob kom tsim nyog yuav tsis tsuas yog kom tau cov khoom kub thiab ntseeg tau tias cov khoom lag luam zoo, tab sis kuj tsis txuag cov nyiaj tab sis kuj ua kom cov khoom lag luam zoo. Kev teeb tsa tsis raug, thermal conductivity, thiab lub sijhawm lag ua yog qhov yuam kev tseem ceeb hauv kev siv thermocouples.
