Waea Papatahi CuNi44 (ASTM C71500/DIN CuNi44) Nikara-Parahi Koranu mō ngā Wāhanga Hiko
Whakaahuatanga Hua
Waea Papatahi CuNi44
Ngā Painga o te Hua me ngā Rerekētanga o te Tohu
He mea tino pai te waea papatahi CuNi44 mō tōna pumau ātete hiko me tōna ngāwari ki te mahi ā-mīhini, ā, he mea pai rawa atu tēnei mō ngā wāhanga hiko tino tika. Ki te whakatauritea ki ngā koranu parahi-nikara rite tonu ki te CuNi10 (Constantan) me te CuNi30, he nui ake te ātete o te CuNi44 (49 μΩ·cm vs. 45 μΩ·cm mō te CuNi30) me te iti ake o te tauwehenga pāmahana ātete (TCR), e whakarite ana i te iti o te nekehanga ātete i roto i ngā taiao rerekē te pāmahana. Kāore i rite ki te CuNi10, e tino pai ana ki ngā tono thermocouple, ko te huinga taurite o te āhua me te pumau ātete o te CuNi44 he mea pai mō ngā ātete tino tika, ngā ine taumahatanga, me ngā whakawhiti iahiko. Ko tōna hoahoa whakawhiti-wāhanga papatahi ka whakarei ake i te tohatoha wera me te ōritetanga o te whakapā ki te whakatauritea ki ngā waea porowhita, ka whakaiti i ngā wāhi wera i roto i ngā tono iahiko teitei.
Ngā Whakaingoatanga Paerewa
- Kounga Koranu: CuNi44 (Parahi-Nikara 44)
- Nama UNS: C71500
- Paerewa DIN: DIN 17664
- Paerewa ASTM: ASTM B122
Ngā Āhuatanga Matua
- Ātete Tino Pai: Ko te TCR o te ±40 ppm/°C (-50°C ki te 150°C), he pai ake i te CuNi30 (±50 ppm/°C) i roto i ngā tono tino tika.
- Ātete Teitei: 49 ± 2 μΩ·cm i te 20°C, e whakarite ana i te whakahaere au pai i roto i ngā hoahoa kiato.
- Ngā Painga o te Kōtaha Papatahi: Te horahanga mata kua nui ake hei whakapai ake i te marara o te wera; te whakapā atu ki ngā papa i roto i te hanga ātete.
- He Āhua Pai Rawa: Ka taea te huri ki ngā ātete āhua piripono (matotoru 0.05mm–0.5mm, whānui 0.2mm–10mm) me ngā āhuatanga ā-ringa ōrite.
- Ātete ki te Waikura: Ātete ki te waikura o te hau me te wai māori, he pai mō ngā taiao ahumahi uaua.
