High Temperature Thermocouple Wire Type E Meets International Standards For And Reliability In Any Environment

NiCr-CuNi Type E Thermocouple Wire is a thermocouple type designed for high sensitivity and excellent performance in environments requiring precise temperature measurements. It is particularly suitable for oxidizing or inert atmospheres and offers the highest thermoelectric output among standard thermocouples, making it ideal for low-temperature applications.

NiCr-CuNi Type E Thermocouple Wire offers exceptional performance for low and moderate temperature measurements due to its high sensitivity and wide temperature range. Its resistance to oxidation and cost-effectiveness make it a reliable choice in various industries, including scientific research, cryogenics, and general industrial applications. Proper selection of insulation and protection is crucial for maintaining accuracy and longevity in challenging environments.

Key Features of NiCr-CuNi (Type E) Constantan Thermocouple Wire include:

• Temperature Range:

Standard Range: −200°C to 900°C (−328°F to 1,652°F).

Performs particularly well in cryogenic (low-temperature) applications due to its high sensitivity.

• Thermoelectric Voltage:

Generates a high thermoelectric voltage based on the Seebeck Effect.

Typical thermoelectric sensitivity: Approximately 68 µV/°C at 0°C, the highest among standard thermocouples.

• Corrosion Resistance:

Performs well in oxidizing and inert atmospheres.

Should not be used in reducing, sulfurous, or vacuum environments as these can degrade the materials.

Applications:

• Ideal for low-temperature applications due to its high sensitivity.
• Used in cryogenics, heat treating, scientific research, and other environments where precise low-temperature measurements are required.
• Common in industrial, laboratory, and aerospace applications.

Cable Insulation and Construction:

Available with various insulation materials, tailored to specific temperature ranges and environments:

• Fiberglass: High-temperature resistance.
• Teflon (PTFE) or PVC: For low-temperature and chemically resistant applications.
• Shielding options: Shielded cables for use in electrically noisy environments.

Accuracy (Tolerance):

Standard Tolerance: ±1.7°C or ±0.5% of the temperature (whichever is greater).

Special Tolerance: ±1.0°C or ±0.4% of the temperature (whichever is greater).

Advantages:

• High Sensitivity: The highest thermoelectric output of all standard thermocouples, making it ideal for low-temperature precision measurements.
• Wide Temperature Range: Suitable for both low and moderate temperature applications.
• Cost-Effective: Less expensive than noble metal thermocouples like Type R or S.

Limitations:

• Susceptible to degradation in reducing or sulfurous environments.
• Not recommended for use in vacuum applications due to potential oxidation and material loss.
