Product Description
Constantan Hlau nrog nruab nrab resistivity thiab tsis tshua muaj kub coefficient ntawm tsis kam nrog lub tiaj tsis kam / kub nkhaus hla qhov dav dua li "manganins". Constantan kuj qhia tau hais tias corrosion kuj zoo dua li tus txiv neej ganins. Kev siv yuav raug txwv rau ac circuits.
Constantan 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.
