He mea nui nā mea hana ana wela o nā Thermocouples ma nā ʻoihana like ʻole. Ma waena o nā ʻano like ʻole, kū nā platinum-rhodium thermocouples no kā lākou hana wela kiʻekiʻe a me ka pololei. E ʻeli kēia ʻatikala i nā kikoʻī o nā platinum-rhodium thermocouples, me kā lākou hoʻohana ʻana, ka uea thermocouple maikaʻi loa, a me ka haku mele ʻana o nā thermocouples ʻano S.
He aha nā ʻano o nā thermocouples platinum-rhodium?
ʻEkolu mau ʻano nui onā thermocouples platinum-rhodiumʻAno-B, ʻano-R, a me ke ʻano-S. Ua ʻike ʻia kēia mau thermocouples no ko lākou kūpaʻa wela kiʻekiʻe a hoʻohana pinepine ʻia i nā noi e pono ai ke ana pololei o ka mahana.
1. ʻAno B (Platinum 30% Rhodium/Platinum 6% Rhodium): Pae mahana: 0°C a i 1700°C, Nā Hiʻohiʻona: He paʻa loa nā thermocouples ʻAno B a hiki ke ana i nā mahana kiʻekiʻe loa. Hoʻohana pinepine ʻia i loko o nā umu a me nā umu wela kiʻekiʻe.
2. ʻAno R (Platinum 13% Rhodium/Platinum): Pae mahana: -50°C a i 1600°C, Nā Hiʻohiʻona: Hoʻokō nā thermocouples ʻAno R i kahi kaulike maikaʻi ma waena o ke kumukūʻai a me ka hana. Hoʻohana ʻia lākou i nā ʻano hana ʻoihana like ʻole e like me ka hana aniani a me ka hana metala.
3. ʻAno S (Platinum 10% Rhodium/Platinum): Pae mahana: -50°C a i 1600°C, Nā Hiʻohiʻona: Ua ʻike ʻia nā thermocouples ʻAno S no ko lākou pololei a me ke kūpaʻa. Hoʻohana pinepine ʻia lākou i loko o nā keʻena hoʻokolohua a me nā ʻoihana kahi e koʻikoʻi ai ka kaohi ʻana i ka mahana pololei.
He aha ka uea thermocouple maikaʻi loa?
ʻO ke kumu hoʻohālikelike no ka hoʻoholo ʻana i ka maikaʻi o kahi huahana aia i kona ʻano. He ʻokoʻa nā kūlana maikaʻi o nā huahana like ʻole, a hiki ke hoʻoholo ʻia ke ʻano o ka uea thermocouple platinum-rhodium mai nā waiwai ʻehā aʻe. ʻO ka mea mua, he paʻa kiʻekiʻe ka mahana o ka uea platinum-rhodium a hiki ke kū i nā mahana kiʻekiʻe loa me ka ʻole o ka hōʻino ʻana. Hōʻoia kēia kūpaʻa i ke ana pololei ʻana o ka mahana ma luna o kahi ākea ākea. ʻO ka lua, hāʻawi nā thermocouple platinum-rhodium i ke ana pololei ʻana o ka mahana, e kūpono ai lākou no nā noi e pono ai ka pololei. Eia kekahi, he kiʻekiʻe ke kūpaʻa o ka platinum a me ka rhodium i ka palaho, e hōʻoia ana i ke ola lawelawe a me ka hilinaʻi o ka uea thermocouple i nā ʻano ʻino. ʻO ke kūpaʻa o ka uea thermocouple platinum-rhodium e kūpono ia no ka hoʻohana lōʻihi i nā noi ʻoihana, e hōʻemi ana i ka pono no ka hoʻololi pinepine. Inā kiʻekiʻe loa nā koi no ka pololei o ke ana ʻana, ke kūpaʻa, ke kūpaʻa oxidation, a me nā mea ʻē aʻe, ʻo ka uea thermocouple platinum-rhodium ke koho maikaʻi loa.
He aha ka hoʻohana ʻana o ka uea thermocouple platinum?
Uea thermocouple Platinumhe ʻāpana koʻikoʻi ia i ke kūkulu ʻana i nā thermocouple platinum-rhodium. ʻO kona mau waiwai kūikawā e hoʻolilo i ka uea thermocouple platinum-rhodium i kūpono no nā ʻano hana wela kiʻekiʻe. I ka ʻoihana aerospace, hoʻohana ʻia ka uea thermocouple platinum e ana i ka mahana o nā mīkini jet a me nā ʻāpana wela kiʻekiʻe ʻē aʻe. He mea koʻikoʻi ke ana ʻana o ka mahana pololei no ka palekana a me ka hana o nā lako aerospace. Hoʻohana ʻia ka uea thermocouple platinum i nā umu ʻoihana e nānā a kāohi i nā mahana kiʻekiʻe. ʻO ko lākou kūpaʻa a me ka pololei e hōʻoia i ka hana ʻana o ka umu i loko o ka pae mahana e pono ai, no laila e hoʻomaikaʻi ana i ka pono a me ka maikaʻi o ka huahana. Eia kekahi, pono ke kaʻina hana aniani i ka kaohi mahana pololei, a hoʻohana ʻia ka uea thermocouple platinum e nānā i ka mahana o nā umu aniani e hōʻoia i ka hana aniani kūlike a kiʻekiʻe. I ka noiʻi ʻepekema, he mea nui ke ana ʻana o ka mahana pololei no nā hoʻokolohua a me ka hōʻiliʻili ʻikepili. Hoʻohana ʻia ka uea thermocouple platinum e ana i ka mahana i nā hoʻokolohua like ʻole i loko o ka hale hana, e hāʻawi ana i ka ʻikepili hilinaʻi a pololei.
He mea hana koʻikoʻi nā thermocouples Platinum-rhodium (me nā ʻano B, R, a me S) no ke ana pololei ʻana i ka mahana i nā noi wela kiʻekiʻe. I ke koho ʻana i ka uea thermocouple maikaʻi loa, ʻo nā thermocouples platinum-rhodium ka koho mua no ka mea hana maikaʻi lākou i nā ʻano ʻino. He kuleana koʻikoʻi ko nā thermocouples Platinum-rhodium i nā ʻoihana like ʻole, e hāʻawi ana i ka pololei a me ke kūpaʻa e pono ai no nā noi wela kiʻekiʻe.
