Kev piav qhia txog khoom
Hom R Thermocouple Hlau
Txheej Txheem Cej Luam Khoom
Hom R thermocouple hlau yog ib qho thermocouple hlau muaj nqis siab uas muaj cov hlau platinum-rhodium 13% alloy (ceg zoo) thiab platinum ntshiab (ceg tsis zoo). Nws yog ib feem ntawm tsev neeg platinum-rhodium thermocouple, muab kev ruaj khov thiab raug zoo hauv qhov chaw kub siab, tshwj xeeb tshaj yog nyob rau hauv qhov ntau ntawm 1000 ° C txog 1600 ° C. Piv rau Hom S thermocouples, nws muaj cov ntsiab lus rhodium siab dua hauv ceg zoo, muab kev ua tau zoo dua hauv kev siv kub siab ntev.
Cov Qauv Txheem
- Hom Thermocouple: R-hom (Platinum-Rhodium 13-Platinum)
- IEC Txheem: IEC 60584-1
- ASTM Tus Qauv: ASTM E230
Cov Nta Tseem Ceeb
- Kev Ruaj Ntseg Kub Siab: Kub ua haujlwm ntev txog li 1400 ° C; siv luv luv txog li 1700 ° C
- Kev Ua Tau Zoo Tshaj Plaws: Chav Kawm 1 kam rau siab ntawm ±1.5 ° C lossis ±0.25% ntawm kev nyeem ntawv (qhov twg loj dua)
- Tus Nqi Qis Tshaj: ≤0.05% thermoelectric muaj peev xwm hloov pauv tom qab 1000 teev ntawm 1200 ° C
- Kev Tiv Thaiv Oxidation: Kev ua tau zoo heev hauv oxidizing thiab inert atmospheres (tsis txhob txo qhov chaw ib puag ncig)
- Lub Hwj Chim Thermoelectric Siab Dua: Tsim 10.574 mV ntawm 1500 ° C (qhov chaw sib txuas ntawm 0 ° C)

Cov Lus Qhia Txog Khoom
| Khoom | Cov Lus Qhia Tshwj Xeeb |
|---|---|
| Ntev ib lub Spool | 5m, 10m, 20m, 50m (cov khoom siv hlau muaj nqis) |
| Qhov Chaw Tiav | Annealed, daim iav ci (tsis muaj txheej oxide) |
| Ntim Khoom | Ntim nrog lub tshuab nqus tsev kom kaw rau hauv cov thawv uas muaj argon kom tiv thaiv kev ua qias tuaj |
| Kev kho kom raug | NIST-traceable nrog daim ntawv pov thawj ntawm thermoelectric potential |
| Cov Kev Xaiv Tshwj Xeeb | Kev ntxuav tshwj xeeb rau kev siv purity siab heev, txiav kom ntev |
Cov Ntawv Thov Ib Txwm Muaj
- Kev sim cav aerospace (chambers kub hnyiab)
- Cov cub tawg ua kom muaj kev kub siab (sintering ntawm cov khoom siv ceramics siab heev)
- Kev tsim khoom siv semiconductor (silicon wafer annealing)
- Kev tshawb fawb txog hlau (kev sim cov ntsiab lus yaj ntawm superalloy)
- Kev tsim cov iav fiber (cheeb tsam cua sov kub siab)
Peb kuj muab cov khoom siv ntsuas kub hom R, cov khoom sib txuas, thiab cov xov hlau txuas ntxiv. Vim tias cov hlau muaj nqis muaj nqis ntau, cov qauv pub dawb muaj nyob rau hauv qhov ntev tsawg (≤1m) thaum thov, nrog rau daim ntawv pov thawj khoom siv thiab cov ntawv qhia txog kev tshuaj xyuas cov khoom tsis huv.
