NiCr-NiSi Type K Thermocouple Wire And Cable Durable And Versatile For Industrial And Scientific

NiCr-NiSi Type K Thermocouple Wire and Cable is a widely used thermocouple material for temperature measurement applications. It is composed of a positive leg made from Nickel-Chromium alloy (NiCr) and a negative leg made from Nickel-Silicon alloy (NiSi). Type K thermocouples are known for their broad temperature range, reliability, and resistance to oxidation. NiCr-NiSi Type K Thermocouple Wire and Cable is an economical, durable, and reliable choice for high-temperature measurement applications. Its wide temperature range, resistance to oxidation, and availability in various forms make it a versatile tool for industrial and scientific applications.

Positive wire is yellow, negative wire is red.

Thermocouple temperature range and tolerance

Key Features of Type K Thermocouple Wire:

• Wide Temperature Range

Operates effectively in a range of -200°C to 1260°C (-328°F to 2300°F), suitable for both low and high-temperature environments.

• High Accuracy and Sensitivity

Provides accurate and reliable temperature measurements with a standard tolerance of ±2.2°C or ±0.75% of the measured temperature.

• Good Oxidation Resistance

Performs well in oxidizing atmospheres due to the high chromium content in the positive leg.

Suitable for use in inert or oxidizing environments but not ideal for reducing or sulfur-containing atmospheres.

• Durable and Long-Lasting

Designed for durability and long service life, even in high-temperature applications.

• Electrical Properties

Produces a stable thermoelectric voltage (Seebeck coefficient) of approximately 41 µV/°C at 1000°C.

• Material Composition

Positive Leg (NiCr): Typically 90% Nickel and 10% Chromium.

Negative Leg (NiSi): A combination of Nickel, Silicon, and small amounts of Manganese or Aluminum.

Applications

• Widely used in industries such as metalworking, power generation, petrochemical, and manufacturing.
• Common applications include furnaces, kilns, engines, and heat exchangers.

Cable Options

• Available in bare wire, insulated wire, and cable forms with various insulation materials, such as fiberglass, Teflon, or ceramic, to suit specific environments.
• Shielded or unshielded cables are available for electrical noise reduction in sensitive applications.

Advantages of Type K Thermocouple Wire and Cable:

• Broad usability across a wide temperature range.
• Relatively low cost compared to other thermocouple types like Type R or S.
• Robust and resistant to environmental factors like oxidation and wear.

Limitations:

• Not suitable for reducing atmospheres or sulfurous environments, which can degrade the wire.
• May experience drift or inaccuracy at very high temperatures over extended periods.
