NiCr-CuNi Type E Constantan Thermocouple Wire A Must-Have for Industrial and Scientific Applications

NiCr-CuNi Type E Constantan Thermocouple Wire is a versatile temperature measurement tool consisting of two dissimilar metal wires: the positive leg made of nickel-chromium (NiCr) and the negative leg made of constantan (copper-nickel, CuNi). It operates effectively within a temperature range of -200°C to 900°C, making it suitable for both low and high-temperature applications. Type E thermocouples are appreciated for their high sensitivity and accuracy, particularly in the low-temperature range up to 300°C.

The alloy's composition provides good corrosion resistance in oxidizing or inert atmospheres, though it should be avoided in reducing atmospheres or those containing sulfur. With a non-magnetic nature, it is also beneficial in environments with magnetic fields. The physical properties of the NiCr wire include a density of approximately 8.5 g/cm³, a melting point of 1427°C, and a tensile strength of ≥490 MPa, while the Constantan wire has a density of 8.5 g/cm³, a melting point of 1220°C, and a tensile strength of ≥390 MPa.

Type E thermocouples find applications in various industries, including gas burners for ovens, freezers, engine protection, and high-temperature control in iron casting. They are manufactured to meet international standards like IEC60584-1, ensuring quality and reliability in temperature measurement and control.

Color codes of thermocouple ( E type )

Type E thermocouple has the largest EMF output and highest sensitivity, so it is ideal for measuring small temperature change. It also has good stability in the low temperature range up to 300 ℃ , and good property of anti-corrosion in humidity atmosphere. It is recommended for oxidizing or inert atmospheres, but cannot be used directly in reducing atmosphere and atmosphere with sulphur gases.
