E like me kā mākou e ʻike ai, ʻo ka hana nui o nā thermocouple ke ana a mālama i ka mahana. Hoʻohana nui ʻia lākou i nā ʻoihana e like me ka petrochemical, pharmaceutical a me ka hana ʻana. I nā kaʻina hana ʻoihana, pili pono ka nānā ʻana i ka wela me ka hoʻokele maikaʻi o ka huahana a me ka hoʻomaikaʻi ʻana i ka hana. No laila, ʻo ka platinum-rhodium thermocouple wire he mea hilinaʻi a pololei hoʻi i waena o nā ʻano huahana.
Akā he ahauea thermocouple platinum-rhodium? ʻIke loa, he thermocouple i haku ʻia i ʻelua metala makamae, platinum a me rhodium, i hoʻolālā kūikawā ʻia e kū i nā wela kiʻekiʻe a hāʻawi i ke ana wela kūpono ma lalo o nā kūlana koʻikoʻi. Ua koho pono ʻia nā metala ʻelua no ko lākou mau wahi hoʻoheheʻe kiʻekiʻe, ka pale ʻana i ka corrosion a me ka laulā ākea. ʻO nā ʻano mea maʻamau o ka uea thermocouple platinum-rhodium a mākou e ʻike nei he ʻano S-type (platinum-10% rhodium/platinum) a me R-type (platinum-13% rhodium/platinum) thermocouple.
He mau hiʻohiʻona koʻikoʻi ka uea thermocouple Platinum-rhodium. ʻO ka mea mua, hiki i ka platinum-rhodium thermocouple uea ke kū i nā mahana a hiki i 1600 ° C (2912 ° F), kūpono ia no nā noi wela kiʻekiʻe e like me ka hana wela, ka nānā ʻana i ka umu a me ka hana aerospace. ʻO ka lua, ʻo ka hui pū ʻana o ka platinum a me ka rhodium i ka uea thermocouple e hōʻoia i ka paʻa maikaʻi a me ka hoʻihoʻi hou ʻana o ke ana wela, ʻoiai ma lalo o nā kūlana hana paʻakikī. Eia kekahi, ʻo ka platinum-rhodium thermocouple uea he ikaika ka corrosion resistance, a me ka manawa pane wikiwiki, a hiki i ka uea ke hoʻokō i ke ana wela wikiwiki a pololei, he mea koʻikoʻi i nā kaʻina hana ʻenehana.
Hoʻohana nui ʻia ʻo Platinum-rhodium thermocouple uea i nā ʻoihana ʻoihana me nā koi kiʻekiʻe loa no ke ana wela a me ka hoʻomalu. No ka laʻana, i ka ʻoihana mālama wela, hoʻohana ʻia ka uea platinum-rhodium thermocouple e nānā a mālama i ka mahana o nā umu, nā umu a me nā kaʻina hana wela e hōʻoia i ka loaʻa ʻana o nā waiwai waiwai. Eia kekahi, ke hilinaʻi nei ka ʻoihana aerospace i ka uea platinum-rhodium no ka nānā pono ʻana i ka mahana i ka wā o ka hana ʻana o nā ʻāpana mokulele, nā ʻāpana ʻenekini a me nā mea nui aerospace. Hoʻohana ka ʻoihana aniani a me ka ceramic e nānā i ka mahana o nā kilns a me nā kapuahi i hoʻohana ʻia i ka hana ʻana i nā kīʻaha aniani, nā seramika a me nā mea refractory.
I ka pōkole,uea thermocouple platinum-rhodiumhe mea hana koʻikoʻi no ke ana wela kūpono a me ka hoʻomalu ʻana i ke kahua ʻoihana wela kiʻekiʻe. ʻO kāna hana maikaʻi loa, ka laulā ākea ākea a me ka hilinaʻi e lilo ia i koho mua no nā ʻoihana me nā koi kiʻekiʻe loa no ka pololei a me ka paʻa. Inā ʻoe e pili ana i ka mālama ʻana i ka wela, ka hana aerospace, ka hana petrochemical, a i ʻole nā hana ʻē aʻe e koi ana i nā ana wela kiʻekiʻe, ʻo ka platinum-rhodium thermocouple wire e hāʻawi i ka pololei a me ka lōʻihi e pono ai e hōʻoia i ka hana kaʻina hana maikaʻi loa a me ka maikaʻi o ka huahana.
