Mkpịsị Nickel CuNi44 / Constantan nke ọla kọpa, Mkpịsị Alloy maka Resistors na ịgbado ọkụ

Nkọwa Dị Mkpirikpi:

Mkpịsị alloy CuNi44 constantan (Copper-Nickel 55/44), obere okpomọkụ nke iguzogide (TCR < ±40 ppm/°C), EMF okpomọkụ dị elu megide ọla kọpa. Ọ dị mma maka resistors waya wirewound ziri ezi, thermocouples, na electrodes combine resistance. Ọkpụrụkpụ site na 0.1mm ruo 3.0mm, obosara ruo 300mm. Ọ na-esi ike ịgbaze na iguzogide nchara.

Ọkwa alloy:CuNi44 (Constantan)

Ihe mejupụtara:Cu ~55%, Ni ~44%, Mn ~1%

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

Nguzogide:0.49 μΩ·m @20°C

EMF ọkụ vs Cu:~42 μV/°C (0-100°C)
