Waya Wathyathyathya wa CuNi44​

Ubwino wa Zamalonda ndi Kusiyana kwa Magiredi​

Waya wa CuNi44 wosalala umadziwika ndi kukhazikika kwake kwapadera pa kukana kwamagetsi komanso kugwira ntchito bwino kwa makina, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pazida zamagetsi zolondola. Poyerekeza ndi ma alloy ofanana a mkuwa ndi nickel monga CuNi10 (Constantan) ndi CuNi30, CuNi44 imapereka kukana kwakukulu (49 μΩ·cm vs. 45 μΩ·cm ya CuNi30) komanso kukana kutentha kochepa (TCR), zomwe zimapangitsa kuti kukana kukhale kochepa m'malo omwe kutentha kumasinthasintha. Mosiyana ndi CuNi10, yomwe imagwira ntchito bwino kwambiri mu thermocouple, kuphatikiza koyenera kwa CuNi44 kwa kupangika bwino komanso kukhazikika kwa kukana kumapangitsa kuti ikhale yoyenera kwambiri pa ma resistors olondola kwambiri, ma strain gauges, ndi ma current shunts. Kapangidwe kake ka flat cross-section kumawonjezeranso kutayika kwa kutentha ndi kufanana kwa kukhudzana poyerekeza ndi mawaya ozungulira, kuchepetsa malo otentha mukugwiritsa ntchito mphamvu zamagetsi zambiri.​

Ma Standard Designs

• Gulu la Aloyi: CuNi44 (Copper-Nickel 44)​

• Nambala ya UNS: C71500​

• Muyezo wa DIN: DIN 17664​

• Muyezo wa ASTM: ASTM B122​

Zinthu Zofunika​

• Kukhazikika Kwambiri kwa Kukana: TCR ya ±40 ppm/°C (-50°C mpaka 150°C), yogwira ntchito bwino kuposa CuNi30 (±50 ppm/°C) pakugwiritsa ntchito molondola.

• Kukana Kwambiri: 49 ± 2 μΩ·cm pa 20°C, kuonetsetsa kuti mphamvu yamagetsi ikuyenda bwino pamapangidwe ang'onoang'ono.

• Ubwino wa Flat Profile: Kuwonjezeka kwa malo pamwamba kuti kutentha kusamathe bwino; kukhudzana bwino ndi zinthu zotetezera kutentha.

• Kupangika Kwabwino Kwambiri: Ikhoza kukulungidwa kuti ikhale yolimba kwambiri (kukhuthala 0.05mm–0.5mm, m'lifupi 0.2mm–10mm) yokhala ndi mawonekedwe ofanana a makina.​

• Kukana Kudzimbidwa: Kukana dzimbiri mumlengalenga ndi madzi abwino, koyenera malo ovuta kwambiri m'mafakitale.

Mapulogalamu Odziwika​

• Zotsutsa za waya zolondola komanso ma current shunts​

• Ma gridi oyesera mphamvu ndi maselo onyamula katundu​

• Zinthu zotenthetsera mu zipangizo zachipatala​

• Chitetezo cha EMI m'mabwalo amphamvu kwambiri

• Kulumikizana kwa magetsi mu masensa a magalimoto​

Timapereka mayankho okonzedwa bwino kuti agwirizane ndi zofunikira zinazake. Zitsanzo zaulere (kutalika kwa 1m) ndi deta yoyerekeza ya magwiridwe antchito ndi CuNi30/CuNi10 zimapezeka ngati mungafune.
