PtRh13-Pt R-Type Thermocouple Ultra-Precise High-Temp Sensing & Steady Thermal Teb
Product Description
Hom R Thermocouple Hlau
Product Overview
Hom R thermocouple hlau yog cov hlau zoo tshaj plaws thermocouple uas muaj platinum-rhodium 13% alloy (zoo ceg) thiab ntshiab platinum (tsis zoo ceg). Nws belongs rau platinum-rhodium thermocouple tsev neeg, muab kev ruaj ntseg zoo dua thiab raug nyob rau hauv qhov chaw kub kub, tshwj xeeb tshaj yog nyob rau thaj tsam ntawm 1000 ° C txog 1600 ° C. Piv nrog rau Hom S thermocouples, nws muaj cov ntsiab lus rhodium ntau dua nyob rau hauv cov ceg zoo, muab kev ua tau zoo hauv cov ntawv thov kub mus ntev.
Standard Designations
- Thermocouple Hom: R-hom (Platinum-Rhodium 13-Platinum)
- IEC Txuj: IEC 60584-1
- ASTM Txuj: ASTM E230
Cov yam ntxwv tseem ceeb
- High-Temperature Stability: Lub sijhawm ua haujlwm ntev mus txog 1400 ° C; siv sijhawm luv txog li 1700 ° C
- Superior Accuracy: Chav Kawm 1 kam rau ntawm ± 1.5 ° C lossis ± 0.25% ntawm kev nyeem ntawv (qhov twg loj dua)
- Tsawg Drift Rate: ≤0.05% thermoelectric muaj peev xwm drift tom qab 1000 teev ntawm 1200 ° C
- Oxidation Resistance: Kev ua tau zoo heev hauv oxidizing thiab inert atmospheres (tsis txhob txo qhov ib puag ncig)
- Siab dua Thermoelectric Fais Fab: Tsim 10.574 mV ntawm 1500 ° C (siv kev sib tshuam ntawm 0 ° C)

Tej kev siv
- Aerospace cav kuaj (high-temperature combustion chambers)
- High-precision industrial furnaces (sintering ntawm advanced ceramics)
- Semiconductor manufacturing (silicon wafer annealing)
- Kev tshawb fawb metallurgical (superalloy melting point test)
- Kev tsim cov iav fiber ntau (qhov kub-kub rau qhov chaw)
Peb kuj muab R-hom thermocouple sojntsuam, txuas, thiab txuas txuas ntxiv. Vim tias muaj txiaj ntsig zoo ntawm cov hlau muaj txiaj ntsig zoo, cov qauv dawb muaj nyob rau hauv qhov ntev ntev (≤1m) raws li qhov kev thov, nrog rau cov ntaub ntawv pov thawj cov ntaub ntawv ntxaws thiab cov ntaub ntawv qhia txog impurity.
