Uea Thermocouple Type B
Nānā Huahana
ʻO ka uea thermocouple Type B he thermocouple metala makamae kiʻekiʻe i loaʻa i ʻelua mau ʻāpana platinum-rhodium: kahi wāwae maikaʻi me 30% rhodium a me 70% platinum, a me kahi wāwae maikaʻi ʻole me 6% rhodium a me 94% platinum. Hoʻolālā ʻia no nā kaiapuni wela kiʻekiʻe loa, ʻo ia ka wela wela loa ma waena o nā thermocouple metala makamae maʻamau, ʻoi aku ka maikaʻi o ke kūpaʻa a me ke kū ʻana o ka oxidation i nā mahana ma mua o 1500°C. ʻO kāna haku mele ʻelua-platinum-rhodium e hōʻemi i ka drift i hoʻokumu ʻia e ka evaporation platinum, e kūpono ia no ke ana wela kiʻekiʻe.
Hoʻokohu maʻamau
- ʻAno Thermocouple: B-type (Platinum-Rhodium 30-Platinum-Rhodium 6)
- IEC Kūlana: IEC 60584-1
- ASTM Kūlana: ASTM E230
- Hoʻopili kala: wāwae maikaʻi - hina; ʻAʻohe wāwae - keʻokeʻo (no IEC 60751)
Nā mea nui
- Kū'ē Kū'ē Kū'ē: Ka mahana hana lōʻihi a hiki i ka 1600 ° C; hoʻohana pōkole a hiki i 1800 ° C
- EMF haʻahaʻa ma nā wela haʻahaʻa: ʻoi aku ka liʻiliʻi o ka thermoelectric puka ma lalo o 50°C, e hōʻemi ana i ka hopena hewa o ka hui anuanu.
- ʻO ke kūpaʻa kiʻekiʻe kiʻekiʻe: ≤0.1% drift ma hope o 1000 mau hola ma 1600 ° C
- Kū'ē'Oxidation: Hana maika'i loa i nā'enewa oxidizing; kū'ē i ka platinum evaporation
- Ka ikaika o ka mīkini: mālama i ka ductility i nā wela kiʻekiʻe, kūpono no nā wahi ʻoihana paʻakikī.

| Hoʻopau ʻili | Hoʻopili ʻia, ʻālohilohi (ʻaʻohe ʻino o ka ʻili) |
| Hoʻopili ʻana | Hoʻopaʻa ʻia i loko o nā pahu titanium i hoʻopiha ʻia i ka argon e pale i ka oxidation |
| Hoʻolālikelike | Hiki ke ʻimi ʻia i nā kūlana wela honua me nā pihi EMF i hōʻoia ʻia |
| Nā koho maʻamau | ʻOki pololei, hoʻomaʻemaʻe kiʻekiʻe |
Nā noi maʻamau
- ʻO nā umu hoʻoheheʻe kiʻekiʻe (keramika a me nā mea refractory)
- ʻO ka hoʻoheheʻe metala (superalloy a me ka hana kila kūikawā)
- ʻO ka hana aniani (nā kapuahi hana aniani lana)
- ʻO ka hoʻāʻo aerospace propulsion (rocket engine nozzles)
- ʻOihana Nukelea (ka nānā ʻana i ka reactor kiʻekiʻe)
Hāʻawi mākou i nā hui thermocouple Type B me nā paipu pale seramika a me nā mea hoʻohui wela kiʻekiʻe. Ma muli o ka waiwai waiwai kiʻekiʻe, ua kaupalena ʻia ka lōʻihi o ka laʻana i ka 0.5-1m ma ke noi ʻana, i hui pū ʻia me nā palapala hōʻoia piha a me nā hōʻike loiloi haumia. Loaʻa nā hoʻonohonoho maʻamau no nā kaiapuni kapuahi kikoʻī.
