ʻO ke kaha nikala keleawe CuNi44 / Constantan, ka kaha nikala hao no nā mea pale a me ka hoʻoheheʻe ʻana Kiʻi i hōʻike ʻia

ʻO ke kaula hao nikala CuNi44 / Constantan, kahi kaula hao no nā mea pale a me ka hoʻoheheʻe ʻana

Wehewehe Pōkole:

ʻO ke kaula hao CuNi44 constantan (Copper-Nickel 55/44), ke koina kū'ē o ke ana wela haʻahaʻa (TCR < ±40 ppm/°C), ka EMF wela kiʻekiʻe vs ke keleawe. Kūpono no nā mea kū'ē uea pololei, nā thermocouples, a me nā electrodes wili kū'ē. Mānoanoa mai 0.1mm a 3.0mm, laulā a hiki i 300mm. Maikaʻi ke kū'ē i ka pala a me ke kūpaʻa i ka ʻino.

Papa Alloy:CuNi44 (Constantan)

Hoʻonohonoho ʻana:Cu ~55%, Ni ~44%, Mn ~1%

ʻO Cuni44 CU-NI-Mn Copper Nickel Alloy resistance Constantan Strip
(Inoa maʻamau: Constant CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,)

ʻO Cuni44he mea hoʻohuihui keleawe-nickel (Cu56Ni44 alloy) i hōʻailona ʻia e ke kū'ē uila kiʻekiʻe, ke ductility kiʻekiʻe a me ke kū'ē maikaʻi i ka pala. He kūpono ia no ka hoʻohana ʻana i nā mahana a hiki i ka 400°C
ʻO nā noi maʻamau no CuNi44 he mau potentiometers paʻa i ka mahana, nā rheostats ʻoihana, nā kū'ē hoʻomaka mīkini uila a me ke ana hoʻohihi.
ʻO ka hui pū ʻana o ke koina mahana liʻiliʻi a me ke kū'ē kiʻekiʻe e hoʻolilo i ka metala i kūpono loa no ka wili ʻana o nā resistors kikoʻī.
Hana ʻia ʻo CuNi44 mai ke keleawe electrolytic a me ka nickel maʻemaʻe. I nā nui uea maikaʻi aʻe, ua kapa ʻia ka alloy e like meʻO Cuni45(Hoʻohuihui wela).

ʻO Constantan Strip me ke kū'ē kūpono a me ke coefficient haʻahaʻa o ke kū'ē me kahi piʻo kū'ē/mahana pālahalaha ma luna o kahi ākea ākea ma mua o nā "manganins". Hōʻike pū ʻo Constantan i ke kū'ē ʻana i ka palaho ma mua o nā man ganins. Hoʻohana pinepine ʻia nā hoʻohana i nā kaapuni ac.

ʻO Constantan kekahi mea maikaʻi ʻole o ka thermocouple ʻano J me ka hao ka mea maikaʻi; hoʻohana ʻia nā thermocouple ʻano J i nā noi mālama wela. Eia kekahi, ʻo ia ka mea maikaʻi ʻole o ka thermocouple ʻano T me OFHC Copper ka mea maikaʻi; hoʻohana ʻia nā thermocouple ʻano T i nā mahana cryogenic.
