Kev kub siab thiab kub siab tungsten-rhenium thermocouples yog cov khoom siv hluav taws xob zoo tshaj plaws ntawm cov thermocouples muaj nyob rau tam sim no. Lawv feem ntau yog siv rau hauv lub tshuab nqus tsev, hydrogen thiab inert gas atmospheres, nrog lub siab tshaj plaws kev khiav hauj lwm kub mus txog 2300℃.Lawv feature zoo linear thermoelectric yam ntxwv, siab thermoelectric zog npaum li cas, ultra- kub tsis kam thiab tsis tshua muaj nqi.Cov hom muaj xws li WRe5-WRe26 (Type C) thiab WRe3-WRe25 (Type .5%.
Peb lub tuam txhab tau coj tus thawj coj hauv kev txhawb nqa thiab siv tungsten-rhenium thermocouples thoob teb chaws pib xyoo 1997, thiab yog ib qho ntawm cov tuam txhab tseem ceeb ntawm tungsten-rhenium thermocouples hauv Suav teb. Peb tuav txoj haujlwm tseem ceeb hauv kev lag luam raws li cov khoom tsim tawm thiab kev ua lag luam sib koom.Peb tau koom nrog tsim lub teb chaws tus qauv Tungsten-Rhenium Thermocouple Wires thiab Reference Tables thiab cov txheej txheem kev lag luam Technical Specifications rau Tungsten-Rhenium Thermocouples.
Our tungsten‑rhenium thermocouples are constructed with protective tubes made of specially processed molybdenum, tantalum, tungsten and alumina, densely filled with high‑temperature insulating materials suitable for corresponding temperatures, and hermetically sealed in a vacuum environment.
Tshwj xeeb, peb qhov kub thiab txias siab tungsten-rhenium thermocouples muaj peev xwm tiv taus qhov kub siab tshaj 1900℃thiab siab siab tshaj 6 MPa yog thawj zaug ua tiav hauv Suav teb. Lub teb chaws patent tau thov rau lub Kaum Ob Hlis 10, 2012 (Patent No. ZL 2012 2 0676417.6).
Ob lub tsho tungsten-rhenium thermocouple nrog alumina thiab molybdenum kuj tseem tuaj yeem siv rau hauv oxidizing cua mus txog 1600 degree, tsim cov txheej txheem rau tungsten-rhenium thermocouples los hloov cov hlau zoo nkauj thermocouples hauv ntau daim ntawv thov.
Tam sim no, daim ntawv thov tseem ceeb ntawm tungsten-rhenium thermocouples yog lub tshuab nqus tsev vacuum kev lag luam. "Nqus" yog hais txog lub xeev uas lub siab nyob rau hauv ib qho chaw muab qis dua tus qauv atmospheric siab.Tus qauv atmospheric siab yog 101325 Pa. Feem ntau:
- 10⁵–10² Pa: lub tshuab nqus tsev vacuum
- 10²–10⁻¹ Pa: nruab nrab lub tshuab nqus tsev
- 10⁻¹–10⁻⁵ Pa: lub tshuab nqus tsev siab
- <10⁻⁵ Pa: ultra‑high vacuum
Tungsten-rhenium thermocouples rau lub tshuab nqus tsev vacuum muaj qhov yuav tsum tau sib khi siab heev. Peb lub tuam txhab tau txais kev kho tshwj xeeb los xyuas kom meej tias qhov tso tawm ntawm cov thermocouple hauv lub tshuab nqus tsev vacuum yog qis dua qhov siab ntawm qhov cub tawg tag nrho.
Hom kev xaiv hom rau tungsten-rhenium thermocouples yog teev nyob rau hauv Hom Tsim Method rau Thermocouples thiab Resistance Temperature Detectors.Cov yam ntxwv tseem ceeb rau kev xaiv muaj nyob rau hauv cov lus hauv qab no:
