I-China CuNi44 / Constantan Copper Nickel Strip, I-Alloy Strip Yokukhiqiza Nokushisela Ama-Resistors

I-CuNi44 / Constantan Copper Nickel Strip, I-Alloy Strip yama-Resistors kanye nokuWelding

Incazelo emfushane:

I-CuNi44 constantan alloy strip (i-Copper-Nickel 55/44), i-coefficient yokumelana nokushisa okuphansi (i-TCR < ±40 ppm/°C), i-EMF ephezulu yokushisa vs ithusi. Ilungele ama-resistor e-wirewound anembile, ama-thermocouple, nama-electrode okushisela ukumelana. Ubukhulu busukela ku-0.1mm kuya ku-3.0mm, ububanzi bufika ku-300mm. Ukushiselwa okuhle kanye nokumelana nokugqwala.

Ibanga le-alloy:I-CuNi44 (Constantan)

Ukwakheka:I-Cu ~55%, i-Ni ~44%, i-Mn ~1%

I-TCR (±40 ppm/°C):≤ ±40 ppm/°C (20-60°C)

Ukumelana:0.49 μΩ·m @20°C

I-EMF Eshisayo vs i-Cu:~42 μV/°C (0-100°C)

Incazelo Yomkhiqizo

I-Cuni44 CU-NI-Mn Copper Nickel Alloy Resistance Constantan Strip
(Igama Elivamile:Constantan CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,)

I-Cuni44iyi-alloy yethusi-nickel (i-Cu56Ni44 alloy) ebonakala ngokumelana okuphezulu kukagesi, ukuguquguquka okuphezulu kanye nokumelana okuhle nokugqwala. Ifanele ukusetshenziswa emazingeni okushisa afinyelela ku-400°C
Izicelo ezijwayelekile ze-CuNi44 ama-potentiometer azinzile ekushiseni, ama-rheostat ezimboni, ukumelana nokuqala kwe-electric motor kanye ne-strain gauge.
Ukuhlanganiswa kwe-coefficient yokushisa ephansi kanye nokumelana okuphezulu kwenza i-alloy ifaneleke ngokukhethekile ekugoqweni kwama-resistor anembile.
I-CuNi44 yenziwe ngethusi le-electrolytic kanye ne-nickel emsulwa. Ngosayizi wentambo encane, i-alloy ibizwa ngokuthiI-Cuni45(I-Thermocouple).
Incazelo Yomkhiqizo

I-Constantan Strip enokumelana okulinganiselwe kanye ne-coefficient ephansi yokumelana nokushisa enokumelana okusicaba/ijika lokushisa phezu kobubanzi obubanzi kune-"manganins". I-Constantan iphinde ibonise ukumelana nokugqwala okungcono kune-man ganins. Ukusetshenziswa kuvame ukukhawulelwa kumasekethe e-ac.

I-Constantan futhi iyisici esingesihle se-thermocouple yohlobo lwe-J lapho i-Iron iyi-positive; ama-thermocouple ohlobo lwe-J asetshenziswa ekusetshenzisweni kokwelapha ukushisa. Futhi, iyisici esingesihle se-thermocouple yohlobo lwe-T ene-OFHC Copper eyi-positive; ama-thermocouple ohlobo lwe-T asetshenziswa emazingeni okushisa acwebezelayo.
