ʻO ka mea mua, he nui nā thermocouple i kala ʻia. ʻO kēia ʻōnaehana waihoʻoluʻu he ʻike wikiwiki, akā pono e hoʻokokoke me ka akahele. Eia kekahi laʻana, maʻano K thermocouple, Aia ma waena o nā thermocouple i hoʻohana nui ʻia ma muli o ko lākou ākea ākea ākea a me ka paʻa maikaʻi, hana maʻamau ka uea maikaʻi i ka chromel a he melemele pinepine ʻia, ʻoiai ʻo ka uea maikaʻi ʻole, i hana ʻia me ka alumel, he ʻulaʻula maʻamau. Eia nō naʻe, ʻokoʻa ke kala - coding standard ma nā wahi like ʻole a i ʻole e like me nā mea hana like ʻole. Ma kekahi mau hoʻonohonoho maʻamau ʻole a i ʻole nā ​​​​mea kahiko, ʻaʻole paha nā kala e hahai i ka ʻaha maʻamau. No laila, mai hilinaʻi wale i ke kala no ka ʻike ʻana; pono e hoohana ia i alakai mua.

ʻO kekahi ala hilinaʻi e nānā i nā mea uea. Hoʻokumu ʻia nā ʻano ʻano thermocouple i nā ʻāpana metala like ʻole, a ua wehewehe ʻia kēlā me kēia ʻano i kahi uea maikaʻi a maikaʻi ʻole e pili ana i kēia mau mea. No ka laʻana, inʻano J thermocouple, ua hana 'ia ka uea maika'i i ka hao, i 'ike 'ia no ka pane maika'i 'ana i kekahi mau pae wela, a 'o ka uea maika'i 'ole he constantan, e hā'awi ana i ka pa'a maika'i a me ka launa pū me ka hao. Ma ka kuhikuhi ʻana i nā kikoʻī ʻano thermocouple kūhelu, e kikoʻī i ka haku mele a me ka polarity o kēlā me kēia ʻano, hiki i nā mea hoʻohana ke hoʻoholo i nā polarities kūpono me ka maopopo loa. Eia kekahi, hele mai kekahi mau thermocouples holomua me nā ʻikepili ʻaʻole i papa inoa wale i nā mea akā hāʻawi pū i ka ʻike hou aku e pili ana i nā hiʻohiʻona uila i manaʻo ʻia e pili ana i nā uea maikaʻi a maikaʻi ʻole.

Hāʻawi nā huahana thermocouple wire o kā mākou hui i nā pono kūʻokoʻa ma kēia ʻano. Mākaʻikaʻi mākou i nā uwea maikaʻi a maikaʻi ʻole ma kā mākou huahana āpau, ʻaʻole wale ma o ke kala maʻamau - coding akā me nā lepili maopopo. Paʻi ʻia nā lepili me ka hoʻohana ʻana i ka inika kiʻekiʻe, ʻaʻole e mae a mae ʻole paha, ʻoiai ma nā wahi ʻoihana paʻakikī. Hoʻomaopopo kēia ʻōnaehana ʻike ʻelua e hiki i nā mea hoʻohana ke hoʻomaopopo wikiwiki a pololei i nā uea, mālama i ka manawa a hōʻemi i ka pilikia o nā pilina hewa.

Eia kekahi, hana ʻia kā mākou mau uea thermocouple mai nā ʻāpana metala kiʻekiʻe me ke kūpaʻa wela maikaʻi a me ka lōʻihi. ʻO ke kaʻina hana e pili ana i ka mana koʻikoʻi i kēlā me kēia pae, mai ke koho ʻana i nā mea maka a hiki i ka ʻeke hope. Inā paha no nā ʻoihana ʻenehana kiʻekiʻe, e like me ka hana kila kahi e hiki ai ke kiʻekiʻe kiʻekiʻe, a i ʻole nā ​​hoʻokolohua ʻepekema pololei e koi ana i ka pololei minuke, hiki i kā mākou huahana ke mālama i ka hana paʻa a me nā hopena ana pololei. Hana pū mākou i nā hoʻāʻo koʻikoʻi i kēlā me kēia pūʻulu o nā uea thermocouple, me nā hoʻāʻo no ka conductivity uila, thermal emf stability, a me ka ikaika mechanical. Me kēia mau kaʻina hoʻomalu koʻikoʻi koʻikoʻi, ke hōʻoiaʻiʻo nei mākou e hoʻokō nā uea maikaʻi a maikaʻi ʻole i kā mākou huahana thermocouple i nā kūlana ʻoihana kiʻekiʻe loa, e hāʻawi iā ʻoe i kahi hopena hilinaʻi no ke ana wela.

I ka hopena, ʻoiai he nui nā ala e ʻike ai i nā uea maikaʻi a maikaʻi ʻole o kahi thermocouple, ke koho ʻana i kā mākou huahana thermocouple kiʻekiʻe kiʻekiʻe e maʻalahi ke kaʻina hana a hōʻoia i ke ana wela kūpono a paʻa. ʻO kā mākou kūpaʻa i ka maikaʻi a me ka hoʻolālā hoʻohana hoʻohana iā mākou i ke koho maikaʻi loa no kāu pono kelepona thermocouple.
