Yuav ua li cas xaiv ntau hom thermocouples?

Thermocouple yog ib qho ntsuas kub feem ntau ntsuas ntsuas hauv cov twj paj nruag ntsuas. 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). Cov tsos ntawm ntau thermocouples feem ntau sib txawv heev vim lawv cov kev xav tau, tab sis lawv cov qauv yooj yim yog ntxig tib yam. Lawv feem ntau yog tsim cov khoom loj xws li cov ntaub ntawv kub, thiab feem ntau yog siv rau cov twj paj nruag, kaw cov twj paj nruag, thiab cov neeg siv hluav taws xob, thiab cov neeg siv hluav taws xob. 1. Platinum platinum Rhodium thermocouple (s-hom) nplai lb} muaj bermocouple xaim:}}}}}. Zoo ECDODE: Platinum Rhodium Alloy Hlau, Ua los ntawm Smelting 90% Platinum thiab 10% piv rau). Tsis zoo electrode: Platinum xaim. Kev ntsuas kub: Ntev lub sij hawm: 1300 Qib, luv luv: 1600 degree. Cov yam ntxwv: (1) Cov khoom siv ruaj khov thiab ntsuas siab qhov tseeb; Tuaj yeem ua rau hauv cov qauv thermocouples lossis siv cov thermocouples. Lub Hom Phiaj: Kuaj lossis pov thawj ntawm lwm cov thermocouples. (2) Qhov ntsuas kub yog qhov kub thiab feem ntau siv los ntsuas kev ntsuas kub siab dua 1000 degree. (3) Kev txo cov roj cua txias (xws li gases uas muaj cov, h2, thiab lwm yam), lawv yuav tsum tau tes tsho thiab tiv thaiv kev tiv thaiv. (4) Cov khoom siv rau cov hlau uas muaj nqis thiab tus nqi yog tus muaj siab. (5) Lub peev xwm Thermoelectric yog qhov tsis muaj zog. 2. Platinum Rhodium {19} platinum rhodium rho tawm: Platinum Rhodium allloy (ua los ntawm smelting 70% platinum thiab 30% rhodium). Cov Hluav Taws Xob Tsis Zoo: Platinum Rhodium Alloy (ua los ntawm Smelting 94% Platinum thiab 6% Rhodium). Cov ntsuas kub ntsuas: Lub sijhawm ntev tau ncav cuag 1600 degree, luv luv luv tuaj yeem ncav cuag 1800 degree.

Cov yam ntxwv: (1) ruaj khov cov khoom siv thiab ntsuas ntsuas siab yog. (2) yooj yim corroded hauv kev txo cov roj. (3) Qhov tsawg-kub thermoelectric muaj peev xwm yog qhov tseem ceeb heev, thiab txias txias kawg hauv qab 50 degree tuaj yeem nyob tsis tau. (4) tus nqi siab. 3. Ntau ob peb qhov tshwj xeeb thermocouples (1), iRidium alloy thermoco thermoco thermocoal, tuaj yeem ntsuas qhov kub siab txog 2100 degree hauv oxidizing huab cua. (2) Tungsten Rhenium Thermocouple tau tsim nyob rau xyoo 1960 thiab tam sim no yog ib qho ntawm qhov zoo dua-kub thermocouples. Nws tuaj yeem siv rau hauv cov pa nqus pa roj av lossis hydrogen media lossis hydrogen media, tab sis muaj cov pa taws kub siab tiv thaiv. Lub domestically products rungsten rhenium tungsten rhenium 20 thermocouple muaj kub ntau ntawm {16} degree thiab calibration qhov tseeb ntawm 1%. (3) Tus kub hlau nickel chromium thermocouple ntsuas thiab tuaj yeem siv nyob rau hauv ntau ntawm {}} k, nrog ib tug rhiab heev ntawm 10 μ v / degree. (4) Cov Palladium Platinum Iridium 15 Thermocouple Thermocoupricle nrog ib lub zog thermocoupric uas muaj Platinum Platinum ntawm qhov kub tib yam. Yog li ntawd, nws tuaj yeem siv nrog cov ntsuas ntsuas ntsuas qhov ntsuas tsis ntau thiab siv tau hauv kev lag luam aviation. (5) Cov hlau Constantan Thermocouple muaj qhov siab rhiab nrog ib qho kev faib tawm ntawm kwv yees li 53 μ v / degree, zoo linearity, thiab yog pheej yig. Nws tuaj yeem siv rau hauv txo cov xov xwm hauv qab 800 degree. Lub ntsiab tsis zoo yog tias hlau yog tus mob oxidation, thiab kev siv bluing kev kho mob tuaj yeem txhim kho nws corrosion tsis kam. (6) Lub thermoelectric muaj peev xwm ntawm tooj liab constantan thermocouple nrog faib chromium npib tsib xee silicon thickocolokhople, kwv yees li 43 μ v / degree. Zoo reprucibility, kev ruaj khov zoo, muaj qhov raug, thiab pheej yig tus nqi. Qhov tsis zoo yog tias tooj liab yog siv rau oxidation thiab yog dav siv nyob rau hauv cov ntsuas kub tsawg dua li 20k txog 473k. 4. Zirconium diboride ceramic theramcasle muaj qhov ntsuas kub ntawm ± 10 degree ntawm 1900-2200 degree. Tab sis nws tseem tsis tau tau txais kev lees paub thoob plaws hauv kev ua lag luam.
