WebWhat is the advantage of copper-constantan over iron-constantan? Explanation: Copper-constantan differs from iron-constantan due to the use of copper instead of iron, along with the possible addition of manganese and iron. This is useful for measuring low temperatures up to -420 F and a maximum limit of 600 F.

WebFor example, an iron wire and a constantan wire can be joined at their ends to form a junction. If the junction is heated to 100°F above ambient, about 3 mV will be generated at the hot junction. This same effect is used as a source of power in a thermopile which is many thermocouples connected together to produce a more powerful output. WebType E (chromel–constantan) has a high output (68 µV/°C), which makes it well suited to cryogenic use. Additionally, it is non-magnetic. Wide range is −270 °C to +740 °C and narrow range is −110 °C to +140 °C. ... The Curie …

Constantan is also used to form thermocouples with wires made of iron, copper, or chromel. It has an extraordinarily strong negative Seebeck coefficient above 0 degrees Celsius, leading to a good temperature sensitivity.
