Thermocouple Bare Wire NiCr-NiSi Type K Thermocouple Wire And Cable For Stable And Repeatable Signals In Industrial Applications

Thermocouple Bare Wire NiCr-NiSi Type K Thermocouple Wire and Cable refers to a widely used thermocouple made from Nickel-Chromium (NiCr) as the positive leg and Nickel-Silicon (NiSi) as the negative leg. Known for its versatility and high-temperature performance, Type K thermocouples are the most commonly used thermocouples in industrial and laboratory applications.

Thermocouple Bare Wire NiCr-NiSi (Type K) thermocouple wire and cable is a reliable and cost-effective choice for temperature measurement in a wide range of applications. Its broad temperature range, good sensitivity, and durability make it ideal for industrial, laboratory, and scientific uses. However, care must be taken to select appropriate insulation and protect it from environments that may degrade its performance, such as reducing atmospheres or those containing sulfur compounds.

Thermocouple temperature range and tolerance

Key Features and Properties of Thermocouple Bare Wire NiCr-NiSi Type K :

• Materials:

Positive Leg (KP): Nickel-Chromium (NiCr)

Composition: ~90% Nickel, ~10% Chromium

Negative Leg (KN): Nickel-Silicon (NiSi)

Composition: ~95% Nickel, ~5% Silicon with trace amounts of other elements like magnesium.

• Temperature Range:

General Range: -200°C to 1,260°C (-328°F to 2,300°F)

Accuracy:

Standard Tolerance: ±2.2°C or ±0.75% of the reading, whichever is greater.

Special Tolerance: ±1.1°C or ±0.4% of the reading, whichever is greater.

• Sensitivity:

The Type K thermocouple has a sensitivity of approximately 41 µV/°C, making it suitable for applications requiring good sensitivity across a wide temperature range.

• Oxidation Resistance:

NiCr: Good resistance to oxidation at high temperatures, making it suitable for use in air or oxidizing environments.

NiSi: Moderate oxidation resistance and performs well in vacuum or inert atmospheres.

• Durability:

Resistant to thermal shock and mechanical stress.

Suitable for harsh industrial environments, especially in furnaces and kilns.

Applications of Thermocouple Bare Wire NiCr-NiSi Type K:

• Industrial Use:

Furnace monitoring
