Whakaahuatanga Hua
Waea Thermocouple Momo B
Tirohanga Whānui o te Hua
Ko te waea thermocouple Momo B he thermocouple konganuku utu nui mahi-teitei e rua ngā koranu platinum-rhodium: he waewae pai me te 30% rhodium me te 70% platinum, me te waewae kino me te 6% rhodium me te 94% platinum. I hangaia mō ngā taiao pāmahana tino tiketike, koinei te mea tino ātete ki te wera i roto i ngā thermocouple konganuku utu nui noa, he tino pai ki te pumau me te ātete ki te waikura i ngā pāmahana neke atu i te 1500°C. Ko tōna hanganga ahurei takirua-platinum-rhodium ka whakaiti i te nekenekehanga i puta mai i te mimiti platinum, he mea tino pai mō te ine pāmahana teitei mō te wā roa.
Ngā Whakaingoatanga Paerewa
- Momo Hononga Wera: Momo-B (Platinum-Rhodium 30-Platinum-Rhodium 6)
- Paerewa IEC: IEC 60584-1
- Paerewa ASTM: ASTM E230
- Waehere Tae: Waewae pai – hina; Waewae kino – mā (e ai ki te IEC 60751)
Ngā Āhuatanga Matua
- Ātete ki te Pāmahana Tino Nui: Te pāmahana mahi roa tae atu ki te 1600°C; te whakamahinga poto tae atu ki te 1800°C
- EMF Iti i ngā Pāmahana Iti: He iti rawa te putanga hiko wera i raro i te 50°C, ka whakaiti i te pānga o te hapa hononga makariri
- Pūmautanga Mahana-Tiketike Pai Rawa: ≤0.1% te nekehanga i muri i te 1000 hāora i te 1600°C
- Ātete ki te Waikura: He mahi tino pai i roto i ngā āhuarangi waikura; ātete ki te mimiti konukawata
- Kaha Ā-Mīhini: Ka mau tonu te ngāwari i ngā pāmahana teitei, he pai mō ngā taiao ahumahi uaua

| Whakarerekētanga | Ka taea te whai i ngā paerewa pāmahana o te ao me ngā pihi EMF kua whakamanahia |
| Ngā Kōwhiringa Ritenga | Te tapahi tika, te whakakanapa mata mō ngā mahi tino parakore |
Ngā tono noa
- Ngā oumu whakawera wera-teitei (ngā rauemi uku me ngā rauemi ātete-wera)
- Te whakarewa whakarewa (te hanga maitai tino pai me te maitai motuhake)
- Te hanga karāhe (ngā oumu hanga karāhe mānu)
- Whakamātautau whakaterenga ā-rangi (ngā pūwero miihini roketi)
- Ahumahi karihi (aroturukitanga tauhohenga pāmahana teitei)
Ka whakaratohia e mātou ngā huihuinga thermocouple Momo B me ngā ngongo tiaki uku me ngā hononga pāmahana teitei. Nā te nui o te uara rauemi, ka whakawhāitihia te roa o te tauira ki te 0.5-1m ina tonoa, me ngā tiwhikete rauemi katoa me ngā pūrongo tātari poke. Kei te wātea ngā whirihoranga ritenga mō ngā taiao oumu motuhake.
