E like me kā kākou e ʻike nei, ʻo ka hana nui o nā thermocouples ke ana a me ka hoʻomalu ʻana i ka mahana. Hoʻohana nui ʻia lākou i nā ʻoihana e like me ka petrochemical, nā lāʻau lapaʻau a me ka hana ʻana. I nā kaʻina hana ʻoihana, pili pono ka nānā ʻana i ka mahana pololei i ka kaohi ʻana i ka maikaʻi o ka huahana a me ka hoʻomaikaʻi ʻana i ka pono o ke kaʻina hana. No laila, ʻo ka uea thermocouple platinum-rhodium kahi koho hilinaʻi a pololei hoʻi i waena o nā ʻano huahana he nui.
Akā he aha ka meauea thermocouple platinum-rhodiumʻIke loa, he thermocouple ia i haku ʻia me ʻelua metala makamae, platinum a me rhodium, i hoʻolālā kūikawā ʻia e kū i nā mahana kiʻekiʻe a hāʻawi i ke ana wela pololei ma lalo o nā kūlana koʻikoʻi. Ua koho pono ʻia nā metala ʻelua no ko lākou mau kiko heheʻe kiʻekiʻe, ke kūpaʻa i ka pala a me ka laulā o ka mahana. ʻO nā ʻano maʻamau o ka uea thermocouple platinum-rhodium a mākou e ʻike nei he S-type (platinum-10% rhodium/platinum) a me R-type (platinum-13% rhodium/platinum) thermocouples.
He nui nā ʻano koʻikoʻi o ka uea thermocouple platinum-rhodium. ʻO ka mea mua, hiki i ka uea thermocouple platinum-rhodium ke kū i nā mahana a hiki i 1600°C (2912°F), e kūpono ai no nā noi wela kiʻekiʻe e like me ka hana wela, ka nānā ʻana i ka umu a me ka hana ʻana i ka aerospace. ʻO ka lua, ʻo ka hui pū ʻana o ka platinum a me ka rhodium i loko o ka uea thermocouple e hōʻoiaʻiʻo ana i ka paʻa maikaʻi loa a me ka hana hou ʻana o ke ana ʻana o ka mahana, ʻoiai ma lalo o nā kūlana hana paʻakikī. Eia kekahi, loaʻa i ka uea thermocouple platinum-rhodium ke kūpaʻa ikaika i ka pala, a me ka manawa pane wikiwiki, a hiki i ka uea ke hoʻokō i ke ana wela wikiwiki a pololei, he mea nui ia i nā kaʻina hana ʻoihana ikaika.
Hoʻohana nui ʻia ka uea thermocouple Platinum-rhodium ma nā kahua ʻoihana me nā koi kiʻekiʻe loa no ke ana ʻana a me ka kaohi ʻana i ka mahana kiʻekiʻe. No ka laʻana, ma ka ʻoihana mālama wela, hoʻohana ʻia ka uea thermocouple platinum-rhodium e nānā a kaohi i ka mahana o nā umu, nā umu a me nā kaʻina hana mālama wela e hōʻoia i ka hoʻokō ʻia ʻana o nā waiwai mea e pono ai. Eia kekahi, hilinaʻi ka ʻoihana aerospace i ka uea platinum-rhodium no ka nānā pono ʻana i ka mahana i ka wā o ke kaʻina hana o nā ʻāpana mokulele, nā ʻāpana mīkini a me nā mea aerospace koʻikoʻi ʻē aʻe. Hoʻohana ka ʻoihana hana aniani a me ka keramika iā ia e nānā i ka mahana o nā umu a me nā umu i hoʻohana ʻia i ka hana ʻana i nā mea aniani, nā keramika a me nā mea refractory.
I ka pōkole,uea thermocouple platinum-rhodiumhe mea hana koʻikoʻi no ke ana ʻana a me ka kaohi ʻana i ka mahana pololei ma ke kahua ʻoihana wela kiʻekiʻe. ʻO kāna hana maikaʻi loa, ka laulā o ka mahana a me ka hilinaʻi e lilo ia i koho mua no nā ʻoihana me nā koi kiʻekiʻe loa no ka pololei a me ke kūpaʻa. Inā ʻoe e komo ana i ka mālama wela, ka hana aerospace, ka hana petrochemical, a i ʻole nā ʻoihana ʻē aʻe e koi ana i nā ana wela kiʻekiʻe, hāʻawi ka uea thermocouple platinum-rhodium i ka pololei a me ke kūpaʻa e pono ai e hōʻoia i ka hana hana maikaʻi loa a me ka maikaʻi o ka huahana.
