NiCr-CuNi Type E Constantan Thermocouple Wire in Engine Protection and High-Temperature Control
NiCr-CuNi Type E Constantan Thermocouple Wire is a temperature-sensing device composed of two distinct metal wires: nickel-chromium (NiCr) for the positive leg and copper-nickel (CuNi or Constantan) for the negative leg. It is designed to operate within a broad temperature range of -200°C to 900°C, making it suitable for a variety of applications.
Key features of Type E thermocouples include high sensitivity, which allows for the detection of small temperature changes, and good accuracy, particularly in the low-temperature range up to 300°C. They also exhibit resistance to corrosion in oxidizing or inert atmospheres, although they should be used with caution in reducing atmospheres or those containing sulfur.
Type E thermocouples are non-magnetic, which is beneficial in applications where magnetic fields are present. They are used in a wide range of industries, including automotive, aerospace, food processing, chemical, and power generation, for temperature measurement and control. Manufactured to comply with international standards, these thermocouples ensure quality and reliability in temperature monitoring.

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.

key features of NiCr-CuNi (Type E) Constantan Thermocouple Wire include:
Positive Leg (NiCr): Composed of a nickel-chromium alloy, providing high resistance and good stability.
Negative Leg (CuNi or Constantan): Composed of a copper-nickel alloy, which is relatively stable and less sensitive to oxidation than pure copper.
-200°C to 900°C (-328°F to 1652°F) for the most common applications, though it can be used outside this range depending on the specific construction and materials.
Especially effective in the lower temperature range, making it ideal for cryogenic and low-temperature applications.
Seebeck coefficient of approximately 68 µV/°C, giving it a high voltage output per degree of temperature change, which allows for better precision in temperature readings.
More sensitive than other thermocouple types (e.g., Type K, Type J) in the lower temperature ranges.
Offers good accuracy, often within ±1.0°C or ±0.75% of the reading, depending on the temperature range.
Type E thermocouples are especially accurate in the range of 0°C to 100°C, where they exhibit the best performance.
The voltage-to-temperature relationship of Type E is relatively linear, particularly at lower temperatures, which improves measurement reliability.
A more linear response translates to more consistent readings and easier calibration.
Type E thermocouples are known for their long-term stability and minimal drift over time, which ensures consistent performance throughout their lifetime.
This makes them suitable for use in precision measurements and calibration applications.
The copper-nickel alloy (Constantan) provides better corrosion resistance than other materials, although it is not as resistant to corrosion as other thermocouples made with platinum or other precious metals.
Type E thermocouples generally perform well in moderate environments.
Applications:
Type E thermocouples, due to their high sensitivity, linear output, and good stability, are preferred in applications where precision is crucial, particularly in the lower temperature ranges.
