Haina CuNi44 / Constantan Parahi Nikara Rīpene, Rīpene Koranu mō ngā Ātete me te Hanga me te Wheketere Whakarewa

Rīpene Nikara Parahi CuNi44 / Constantan, Rīpene Koranu mō ngā Ātete me te Whakarewa

Whakaahuatanga Poto:

Ripanga koranu CuNi44 constantan (Parahi-Nikara 55/44), tauwehenga ātete pāmahana iti (TCR < ±40 ppm/°C), EMF wera teitei ki te parahi. He pai mō ngā ātete waea tika, ngā takirua wera, me ngā irahiko whakarewa ātete. Matotoru mai i te 0.1mm ki te 3.0mm, whānui tae atu ki te 300mm. He pai te tūhono me te ātete waikura.

Whakaahuatanga Hua

Rīpene Constantan ātete ki te Nikara Parahi Cuni44 CU-NI-Mn
(Ingoa Common:Constantan CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,)

Cuni44he koranu parahi-nikara (koranu Cu56Ni44) e tohuhia ana e te ātete hiko teitei, te ngāwari teitei me te ātete waikura pai. He pai mō te whakamahi i ngā pāmahana tae atu ki te 400°C
Ko ngā tono noa mō CuNi44 ko ngā potentiometers pumau pāmahana, ngā rheostats ahumahi, ngā ātete tīmatanga motuka hiko me te ine taumahatanga.
Nā te huinga o te iti o te tauwehenga pāmahana me te ātete teitei, he tino pai te koranu mō te takai o ngā ātete tino tika.
He mea hanga te CuNi44 mai i te parahi hikohiko me te nikara parakore. Mō ngā rahi waea pai ake, ka tohua te koranu heiCuni45(Temahere Whakamahana).
Whakaahuatanga Hua

He Rīpene Constantan me te ātete taurite me te tauwehenga pāmahana iti me te pihi ātete/pāmahana papatahi i runga i te whānuitanga whānui atu i ngā "manganins". He pai ake te ātete waikura o Constantan i ngā man ganins. Ko ngā whakamahinga he mea here noa ki ngā ara iahiko AC.

Ko Constantan anō hoki te huānga kino o te momo takirua wera J me te Rino te mea pai; ka whakamahia ngā momo takirua wera J i roto i ngā mahi whakamahana. Waihoki, koia te huānga kino o te momo takirua wera T me te OFHC Parahi te mea pai; ka whakamahia ngā momo takirua wera T i ngā pāmahana cryogenic.
