Constantan Definition
Resistance alloy ine mwero resistivity uye yakaderera tembiricha coefficent yekupikisa ine flat kuramba/tembiricha curve pamusoro pehupamhi hwakakura kupfuura "manganins".CuNi44 Alloy wire inoratidzawo zvirinani kusaita ngura kupfuura yemurume. Mashandisirwo anowanzo kuve akaganhurirwa kune ac maseketi. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Wire zvakare chinhu chisina kunaka chemhando J thermocouple ine Iron iri iyo yakanaka; Type J thermocouples inoshandiswa mukupisa kurapa maapplication. Zvakare, ndicho chinhu chisina kunaka cherudzi rweT thermocouple ine OFHC Mhangura iyo yakanaka; mhando T thermocouples anoshandiswa pane cryogenic tembiricha.
