ʻAno R Thermocouple Uea
Nānā Huahana
ʻO ke kelepona thermocouple Type R he thermocouple metala makamae kiʻekiʻe i haku ʻia me kahi platinum-rhodium 13% alloy (wāwae maikaʻi) a me ka platinum maʻemaʻe (wāwae maikaʻi ʻole). No ka ʻohana thermocouple platinum-rhodium, e hāʻawi ana i ka paʻa a me ka pololei i nā wahi wela kiʻekiʻe, ʻoi aku ka nui o ka 1000 ° C a 1600 ° C. Hoʻohālikelike ʻia me Type S thermocouples, loaʻa iā ia kahi mea rhodium kiʻekiʻe ma ka wāwae maikaʻi, e hāʻawi ana i ka hana hoʻonui i nā noi wela kiʻekiʻe.
Hoʻokohu maʻamau
- ʻAno Thermocouple: R-type (Platinum-Rhodium 13-Platinum)
- IEC Kūlana: IEC 60584-1
- ASTM Kūlana: ASTM E230
Nā mea nui
- Paʻa Kūlana Kiʻekiʻe: ʻO ka mahana hana lōʻihi a hiki i 1400 ° C; hoʻohana pōkole a hiki i 1700 ° C
- ʻOi aku ka pololei: Papa 1 ka hoʻomanawanui ʻana o ±1.5°C a i ʻole ±0.25% o ka heluhelu ʻana (ʻoi aku ka nui)
- Haʻahaʻa Drift Rate: ≤0.05% thermoelectric hiki ke holo ma hope o 1000 hola ma 1200°C
- Kū'ē Oxidation: Hana maikaʻi loa i ka oxidizing a me ka inert ea (e hōʻemi i nā kaiapuni)
- ʻO ka mana Thermoelectric kiʻekiʻe: Hoʻokumu i 10.574 mV ma 1500°C (ka hui kuhikuhi ma 0°C)

Nā Kūlana Huahana
| 'ikamu | Hōʻike |
|---|---|
| Ka lōʻihi no ka Spool | 5m, 10m, 20m, 50m (mea metala makamae) |
| Hoʻopau ʻili | Hoʻopili ʻia, aniani-mālamalama (ʻaʻohe papa oxide) |
| Hoʻopili ʻana | Hoʻopaʻa ʻia i loko o nā pahu argon i hoʻopaʻa ʻia e pale aku i ka haumia |
| Hoʻolālikelike | NIST-traceable me ka palapala hōʻoia o ka thermoelectric hiki |
| Nā koho maʻamau | ʻOki-i-lōʻihi, hoʻomaʻemaʻe kūikawā no nā noi maʻemaʻe ultra-kiʻekiʻe |
Nā noi maʻamau
- ʻO ka hoʻāʻo ʻana i ka ʻenekini Aerospace (nā keʻena puhi wela kiʻekiʻe)
- ʻO nā kapuahi ʻoihana kiʻekiʻe (sintering of advanced ceramics)
- Ka hana semiconductor (silicon wafer annealing)
- Ka noiʻi metallurgical (superalloy melting point testing)
- Hana ʻia ka fiber aniani (nā ʻāpana umu wela wela)
Hāʻawi pū mākou i nā ʻimi thermocouple type R, nā mea hoʻohui, a me nā uea hoʻonui. Ma muli o ka waiwai kiʻekiʻe o nā metala makamae, loaʻa nā laʻana manuahi i nā lōʻihi palena (≤1m) ma ke noi, me nā palapala kikoʻī kikoʻī a me nā hōʻike loiloi haumia.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
