ʻO ka mea mua, ma ke ʻano o ka haku mele ʻana, J - type thermocouple wire i loko o kahi hui hao - constantan. Hana ʻia ka hao ma ke ʻano he wāwae maikaʻi, aʻo ka constantan (akeleawe - nickel alloy) lawelawe ʻo ia ka wāwae ʻino. ʻO ka ʻokoʻa, K - type thermocouple uea i hana ʻia me ka achromel- hui alumel. ʻO Chromel, ka mea nui i haku ʻia me ka nickel a me ka chromium, ʻo ia ka wāwae maikaʻi, a ʻo ka alumel, kahi nickel - aluminika - manganese - silicon alloy, ʻo ia ka wāwae ʻino. ʻO kēia ʻokoʻa i nā mea e alakaʻi ai i nā ʻano like ʻole o kā lākou ʻano hana.

ʻO ka lua, ʻokoʻa loa nā pae wela e hiki iā lākou ke ana.J - ʻano thermocoupleHiki ke ana maʻamau i nā mahana mai - 210°C a i 760°C. Ua kūpono lākou no nā ʻano noi like ʻole me nā koi wela haʻahaʻa. No ka laʻana, i ka ʻoihana hoʻoponopono meaʻai, hoʻohana maʻamau ʻia nā thermocouple ʻano J-type i nā umu kuke. I ka wā e kālua ai i ka berena, ʻo ka mahana o loko o ka umu mai 150°C a 250°C. Hiki i kā mākou mau uea thermocouple ʻano J-ʻano kiʻekiʻe ke nānā pono i kēia mau mahana, me ka hōʻoia ʻana e kālua ʻia ka palaoa a loaʻa i ke ʻano kūpono. ʻO kekahi noi ma ka hana lāʻau lapaʻau, kahi i hoʻohana ʻia ai nā thermocouple ʻano J-type e ana i ka mahana i ka wā o ka hoʻomaloʻo ʻana i kekahi mau lāʻau. Mālama pinepine ʻia ka mahana ma kēia kaʻina hana i loko o 50 ° C a 70 ° C, a hiki i kā mākou J - type thermocouple uea huahana hiki ke hāʻawi i ka ʻikepili wela hilinaʻi, e mālama ana i ka maikaʻi o nā lāʻau lapaʻau.

K - type thermocouple, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka nui o ke ana wela, mai - 200°C a 1350°C. ʻO kēia ka mea e pono ai lākou i nā noi wela kiʻekiʻe. I ka ʻoihana hana kila,K - ʻano thermocouplehoʻohana ʻia e nānā i ka mahana i loko o ka umu ahi. Hiki ke piʻi i ka 1200°C a i ʻole ke kiʻekiʻe o nā mahana i loko o ka umu ahi. Hiki i kā mākou mau uea thermocouple K - type ke kū i ka wela loa me ka mālama ʻana i ka pololei kiʻekiʻe, e ʻae ana i nā mea hana e hoʻomalu pono i ke kaʻina hana hoʻoheheʻe a hōʻoia i ka maikaʻi o ke kila. Ma ke kahua o ka aerospace, i ka wā o ka hoʻāʻo ʻana i nā ʻāpana mīkini jet, hoʻohana ʻia nā thermocouple K-type e ana i nā kinoea wela kiʻekiʻe i hana ʻia i ka wā e hana ai ka mīkini. Hiki i kēia mau kinoea ke hōʻea i nā mahana kokoke i 1300°C, a hiki i kā mākou huahana thermocouple uea K-type ke hāʻawi i nā heluhelu wela kūpono, he mea nui ia no ka hoʻomohala ʻana a me ka hoʻonui ʻana i nā ʻenekini jet.

ʻO ka pololei kekahi mea nui. Hāʻawi maʻamau nā ʻano thermocouple K-ʻano i ka pololei ʻoi aku ka maikaʻi ma luna o kahi ākea ākea e hoʻohālikelike ʻia me nā thermocouples ʻano J. ʻO ke kūpaʻa o nā thermocouple ʻano K i loko o nā kaiapuni paʻakikī e hāʻawi pū i ko lākou pololei kiʻekiʻe, e hoʻolilo iā lākou i koho makemake no ka noiʻi ʻepekema a me nā kaʻina hana ʻoihana kiʻekiʻe.

Ma Tankii, hana ʻia kā mākou huahana uea thermocouple J a me K me ka mana koʻikoʻi. ʻO kā mākou J - type thermocouple uea e hōʻoiaʻiʻo i ka hana pono i loko o kā lākou pae wela i ʻōlelo ʻia, aʻo kā mākou mau uea thermocouple K - type i hoʻolālā ʻia e kū i nā wela kiʻekiʻe me ka pololei a me ka paʻa. Inā pono ʻoe e ana i nā kaʻina hana refrigeration haʻahaʻa a i ʻole nā ​​hopena ʻenehana wela kiʻekiʻe, hiki i kā mākou huahana uea thermocouple ke hāʻawi iā ʻoe i ka ʻikepili wela kūpono a paʻa, e kōkua ana iā ʻoe e hoʻokō i kāu mau hana a hōʻoia i ka maikaʻi o ka huahana.
