ʻAno B Thermocouple Wire
ʻIke Huahana
ʻO ke kaula thermocouple ʻano B he thermocouple metala makamae hana kiʻekiʻe i haku ʻia me ʻelua mau mea hoʻohui 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 wahi wela kiʻekiʻe loa, ʻo ia ka mea kūpaʻa loa i ka wela ma waena o nā thermocouple metala makamae maʻamau, ʻoi aku ka maikaʻi ma ke kūpaʻa a me ke kūpaʻa oxidation i nā mahana ma mua o 1500°C. ʻO kona ʻano kū hoʻokahi dual-platinum-rhodium e hoʻemi i ka drift i hoʻokumu ʻia e ka platinum evaporation, e kūpono ai no ke ana wela kiʻekiʻe no ka wā lōʻihi.
Nā Hoʻonohonoho Maʻamau
- ʻAno Thermocouple: ʻAno-B (Platinum-Rhodium 30-Platinum-Rhodium 6)
- Kūlana IEC: IEC 60584-1
- Kūlana ASTM: ASTM E230
- Ke Kaʻina Waihoʻoluʻu: Wāwae maikaʻi - hina; Wāwae maikaʻi ʻole - keʻokeʻo (e like me IEC 60751)
Nā Hiʻohiʻona Koʻikoʻi
- Ke Kū'ē Mahana Loa: Ka mahana hana lōʻihi a hiki i ka 1600°C; ka hoʻohana pōkole a hiki i ka 1800°C
- EMF haʻahaʻa ma nā mahana haʻahaʻa: Ka hoʻopuka thermoelectric liʻiliʻi ma lalo o 50°C, e hōʻemi ana i ka hopena hewa o ka hui anu
- Kūlana Kiʻekiʻe Loa: ≤0.1% ka holo ʻana ma hope o 1000 mau hola ma 1600°C
- Ke Kū'ē ʻana i ka Oxidation: Hana maikaʻi loa i nā lewa oxidizing; kū'ē i ka platinum evaporation
- Ikaika Mechanical: Mālama i ka ductility i nā mahana kiʻekiʻe, kūpono no nā ʻano ʻoihana koʻikoʻi

| Hoʻopau ʻili | Hoʻoheheʻe ʻia, ʻālohilohi (ʻaʻohe haumia o ka ʻili) |
| Ka hoʻopili ʻana | Hoʻopaʻa ʻia i loko o nā pahu titanium i piha i ka argon i ka vacuum e pale aku i ka oxidation |
| Ka hoʻoponopono ʻana | Hiki ke hahai ʻia i nā kūlana mahana honua me nā piʻo EMF i hōʻoia ʻia |
| Nā Koho Maʻamau | ʻOki pololei, hoʻopili ʻili no nā noi maʻemaʻe kiʻekiʻe |
Nā Hoʻohana Maʻamau
- Nā umu sintering wela kiʻekiʻe (nā mea seramika a me nā mea refractory)
- Hoʻoheheʻe ʻana i ka metala (superalloy a me ka hana kila kūikawā)
- Hana ʻana i ke aniani (nā umu hana aniani lana)
- Hoʻāʻo hoʻoneʻe aerospace (nā nozzles mīkini rocket)
- ʻOihana nukelea (nānā ʻana i ka reactor wela kiʻekiʻe)
Hāʻawi mākou i nā ʻaha thermocouple ʻAno B me nā paipu pale seramika a me nā mea hoʻohui wela kiʻekiʻe. Ma muli o ke kumukūʻai waiwai kiʻekiʻe, ua kaupalena ʻia ka lōʻihi o ka laʻana i 0.5-1m ma ke noi ʻana, me nā palapala hōʻoia piha o nā mea a me nā hōʻike loiloi haumia. Loaʻa nā hoʻonohonoho maʻamau no nā wahi umu kikoʻī.
