NiCr-CuNi Type E Thermocouple Wire Wide High Sensitivity for Precise Measurements in Various Industries

The NiCr-CuNi Type E thermocouple is a high-sensitivity temperature measurement device composed of a Nickel-Chromium (NiCr) positive leg and a Copper-Nickel (CuNi) negative leg. It operates in a wide temperature range from -200°C to +900°C (-328°F to +1652°F), making it especially suitable for cryogenic and low-temperature applications. With an electromotive force (EMF) output of approximately 68 µV/°C, it is the most sensitive of standard thermocouples.

Type E thermocouples are stable and reliable in oxidizing or inert atmospheres but are not recommended for reducing or sulfur-rich environments due to potential degradation. Their high sensitivity makes them ideal for precision measurements in industrial processes, laboratory setups, and cryogenic systems. Although less versatile than Type K thermocouples for high-temperature work, Type E is preferred for applications requiring accurate readings in low to medium temperature ranges.

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

1.Composition:

• Positive leg: Nickel Chromium (NiCr).
• Negative leg: Copper Nickel (CuNi).
• This combination allows it to measure temperatures effectively in various environments.

2. Temperature Range:

• The Type E thermocouple has a wide temperature range, typically from -200°C to 900°C (-328°F to 1652°F).
• It is ideal for high-precision measurements in applications requiring higher sensitivity.

3. Voltage Output:

• Type E thermocouples produce a small voltage (mV) that correlates with temperature.
• They have a relatively high Seebeck coefficient (sensitivity) compared to other thermocouple types, meaning they provide a stronger signal for a given temperature change.

4. Accuracy:

• Type E thermocouples offer high accuracy and excellent stability over time, particularly in the range of 0 to 600°C.
• Their sensitivity to small temperature changes makes them suitable for applications where precision is crucial.

Applications:

Type E thermocouples are widely used in industries where high-precision temperature monitoring is necessary, such as:

• Laboratories and scientific research.
• Aerospace and electronics manufacturing.
• Heat treatment and kiln operations.
• Cryogenic research, especially due to their ability to measure low temperatures.

Advantages:

• High Sensitivity: Type E thermocouples provide a strong and relatively linear voltage response to temperature changes.
• Wide Temperature Range: Suitable for both cryogenic and moderately high temperatures.
• Excellent Stability: This thermocouple type offers good long-term reliability.
• Corrosion Resistance: The materials used offer good resistance to oxidation and corrosion.

Limitations:

• While it has a good temperature range, Type E thermocouples may not be suitable for extremely high-temperature applications (above 900°C).
• The copper-nickel negative leg can be more susceptible to damage in certain harsh conditions compared to other thermocouple types.

Standards and Calibration:

• Type E thermocouples conform to various international standards, including the ASTM E230 and IEC 60584, ensuring consistent and reliable performance.
