Constantan txhais
Resistance alloy nrog nruab nrab resistivity thiab tsis tshua muaj kub coefficient ntawm tsis kam nrog ib tug ca tsis kam / kub nkhaus nyob rau hauv ib tug dav ntau yam tshaj li "manganins".CuNi44 Alloy hlau kuj qhia tau zoo corrosion kuj tshaj li tus txiv neej ganins. Kev siv yuav raug txwv rau ac circuits. CuNi44 / CuNi40 / CuNi45 Constantan Copper Nickel Alloy Hlau kuj yog qhov tsis zoo ntawm hom J thermocouple nrog Hlau yog qhov zoo; Hom J thermocouples yog siv rau hauv kev kho cua sov. Tsis tas li, nws yog qhov tsis zoo ntawm hom T thermocouple nrog OFHC Copper qhov zoo; Hom T thermocouples yog siv rau ntawm qhov kub thiab txias.
