Tuatahi, he maha ngā thermocouples he tae-kōwae. He tere te tirohanga o tēnei pūnaha tae-kōwae, engari he mea nui kia tupato. Hei tauira, i roto ingā takirua wera momo K, kei roto i ngā thermocouples e whakamahia whānuitia ana nā te whānui o te awhe pāmahana me te pumau pai, ko te waea pai he mea hanga ki te chromel, ā, he maha ngā tae kōwhai, ko te waea kino ia, he mea hanga ki te alumel, he whero te nuinga. Heoi, ka rerekē pea ngā paerewa waehere tae i ngā rohe rerekē, i runga rānei i ngā kaihanga rerekē. I ētahi whakaurunga kore-paerewa, tawhito rānei, kāore pea ngā tae e whai i te tikanga noa. Nō reira, kaua e whakawhirinaki noa ki te tae hei tautuhi; me whakamahi hei aratohu tuatahi.

Ko tētahi atu huarahi pono ko te tirotiro i ngā rauemi waea. He rerekē ngā momo thermocouples e titoa ana i ngā koranu whakarewa rerekē, ā, he waea pai me te waea kino kua tautuhia i ia momo i runga i ēnei rauemi. Hei tauira, i roto ingā hononga wera momo J, he rino te waea pai, e mōhiotia ana mō tōna urupare pai i roto i ētahi awhe pāmahana, ā, he constantan te waea kino, e tuku ana i te pumau me te hototahitanga pai ki te rino. Mā te titiro ki ngā whakatakotoranga momo thermocouple mana, e whakaatu ana i te hanganga tika me te polarity o ia momo, ka taea e ngā kaiwhakamahi te whakatau i ngā polarities tika me te tino mohio. Hei tāpiri, ka tae mai ētahi thermocouple matatau me ngā pepa raraunga e kore e whakarārangi noa i ngā rauemi engari e whakarato ana hoki i ētahi atu mōhiohio mō ngā āhuatanga hiko e tumanakohia ana e pā ana ki ngā waea pai me ngā waea kino.

He tino painga ngā hua waea thermocouple a tā mātou kamupene mō tēnei mea. Ka tohua mārama e mātou ngā waea pai me ngā waea kino i runga i ā mātou hua katoa, ehara i te mea mā te whakamahi i te waehere tae paerewa anake, engari mā te whakamahi hoki i ngā tapanga mārama. Ka tāia ngā tapanga mā te whakamahi i te waituhi kounga teitei, pakari, e kore e memeha, e memeha rānei, ahakoa i roto i ngā taiao ahumahi uaua. Mā tēnei pūnaha tautuhi takirua ka taea e ngā kaiwhakamahi te tautuhi tere me te tika i ngā waea, ka penapena wā, ka whakaiti hoki i te mōrearea o ngā hononga hē.

Heoi anō, he mea hanga ā mātou waea thermocouple mai i ngā koranu whakarewa kounga teitei, he tino pumau te pāmahana me te roa. Ko te tukanga hanga he tino whakahaere kounga i ia wāhanga, mai i te kōwhiringa o ngā rauemi mata ki te takai whakamutunga. Ahakoa mō ngā tono ahumahi pāmahana teitei, pērā i te hanga maitai ka eke te pāmahana ki ngā taumata tino tiketike, ngā whakamātautau pūtaiao tika rānei e hiahia ana kia tino tika, ka taea e ā mātou hua te pupuri i te mahi pumau me ngā hua ine tika. Ka whakahaerehia hoki e mātou he whakamātautau pakari i runga i ia puranga waea thermocouple, tae atu ki ngā whakamātautau mō te kawe hiko, te pumau o te emf wera, me te kaha miihini. Mā ēnei tukanga whakahaere kounga tino pakari, ka oati mātou ka tutuki ngā waea pai me ngā waea kino i roto i ā mātou hua thermocouple i ngā paerewa ahumahi teitei rawa atu, ka hoatu ki a koe he otinga pono mō te ine pāmahana.

Hei whakamutunga, ahakoa he maha ngā huarahi hei tautuhi i ngā waea pai me ngā waea kino o tētahi thermocouple, ko te whiriwhiri i ā mātou hua waea thermocouple kounga teitei ka māmā ake te tukanga, ā, ka whakarite kia tika, kia pumau hoki te ine pāmahana. Nā tō mātou whakapau kaha ki te kounga me te hoahoa ngāwari ki te whakamahi, ko mātou te whiringa pai mō ō hiahia waea thermocouple katoa.
