Kina Constantan Wire CuNi44 - Uea Alloy Palekana TCR Haʻahaʻa no ka Hana ʻana a me ka Hale Hana o nā Resistors Precision

ʻO Constantan Wire CuNi44 - Uea Alloy Palekana TCR Haʻahaʻa no nā Resistors Precision

Wehewehe Pōkole:

ʻO ke uea Constantan CuNi44 (Cu55/Ni44/Mn1), ke koina kū'ē wela haʻahaʻa loa (TCR ≤ ±40 ppm/°C) a me ka EMF wela kiʻekiʻe vs keleawe. Kūpono no nā mea pale wili uea pololei, nā alakaʻi hoʻonui thermocouple, a me ka ʻike ʻana i ke au haʻahaʻa. ʻO ke anawaena mai 0.05mm a i 2.0mm, i hāʻawi ʻia ma nā spools a i ʻole i nā lōʻihi i hoʻopololei ʻia. Maikaʻi ke kūʻai aku a me ke kūpaʻa lōʻihi. MOQ 20kg, loaʻa ka laʻana.

ʻO CuNi44 Constantan Resistance Alloy Wire no nā Resistors Precision & Thermocouples

Wehewehe Huahana:

ʻO ke kinikini CuNi44 (ʻike ʻia hoʻi ʻo Constantan, Alloy 300, Cuprothal 294, Cupron) he kinikini kūpaʻa keleawe-nickel me ka nui o ka nickel he 44%. Loaʻa iā ia kahi coefficient pale wela haʻahaʻa loa (TCR), e kūpono loa ia no nā pale pololei, nā shunt, nā uea hoʻolōʻihi thermocouple, a me nā noi hoʻomehana wela haʻahaʻa.

Hāʻawi kā mākou uea CuNi44 i ke kūpaʻa kūpaʻa maikaʻi loa, ka hiki ke hoʻopili maikaʻi ʻia, a me ke kūpaʻa lōʻihi. Hoʻohana nui ʻia ia i nā mea uila, nā mea ʻike kaʻa, nā ʻōnaehana hoʻomalu aerospace, a me nā lako hana hoʻokolohua.

Hiki iā mākou ke hoʻolako i ka uea poepoe, ka uea pālahalaha, a me ka lipine/ʻāpana i nā anawaena like ʻole a me nā hoʻomanawanui
