    Manufacture Type K Thermocouple Extension Wire (Nickel ...
    A Nickel-Chromium (NiCr) temperature sensor, commonly known as a Type K thermocouple (NiCr-NiAl or Chromel-Alumel), is a versatile, cost-effective, and widely used sensor for measuring temperatures from approximately -200°C to +1,350°C. Known for excellent oxidation resistance and durability, they are the industry standard for high-temperature applications in manufacturing, HVAC, and aerospace. 
    Key Features & Specifications 
    • Composition: Positive leg is Nickel-Chromium (Chromel), negative leg is Nickel-Aluminum (Alumel).
    • Temperature Range: Typically -200°C to +1,372°C (-328°F to +2,501°F).
    • Sensitivity: Approximately

    • Accuracy: Standard is usually

      .
    • Durability: Good resistance to oxidation and corrosion, making them suitable for long-term use in harsh environments. 
    Common Applications 
    • Industrial Processes: Kilns, furnaces, and casting.
    • HVAC: Furnace and heat exchanger monitoring.
    • Manufacturing: Plastic molding and food processing.
    • Aerospace: Jet engine and exhaust gas temperatures. 
    Advantages and Disadvantages 
    • Pros: Wide temperature range, cost-effective, high accuracy, robust.
    • Cons: Susceptible to "green rot" (oxidation at low-oxygen levels), less accurate than PT100s at low temperatures, and vulnerable to magnetic interference. 
    Common Product Variants 
    • K-Type NiCr-Ni Immersion Sensor: Suitable for liquids, priced around $154 USD, with high-temperature capabilities.
    • Nickel-Chromium Shielded Thermocouples: Mineral-insulated options provide fast response times. 
    Note: For low-temperature precision in building automation, Nickel (Ni1000) RTD sensors are often used, which differ from the High-temperature Type K NiCr thermocouples described above.

    Is nickel-chromium the same as nichrome?
    Nickel chrome alloys, commonly referred to as Nichrome, stand out as versatile materials with a unique composition of nickel, chromium, and sometimes iron. The chemical formula for these alloys is NiCr, and in the presence of iron, it becomes NiFeCr.

    What is a nickel resistance temperature detector?
    Nickel Resistance Temperature Detectors

    Nickel is also used as a resistance element for RTDs in industrial applications. Nickel RTDs have good corrosion resistance and are less expensive than platinum RTDs, but nickel ages rapidly and, over time, they lose their accuracy.

    What happens if a thermocouple touches metal?
    There is the claim that contaminating the tip of a thermocouple with other metals will lead to a wrong reading. It is for example claimed that solder touching the tip will not allow you to read an accurate solder iron temperature. This is not the case, other metals at the thermocouple tip do not impact the measurement.

    Thermocouple tip contamination with other metals has no effect
