NiCrSi-NiSiMg Type N Thermocouple Wire with Improved EMF Drift and Extended Life for Temperature Control
NiCrSi-NiSiMg Type N Thermocouple Wire is a high-precision thermocouple made from a combination of Nickel-Chromium-Silicon (NiCrSi) as the positive leg and Nickel-Silicon-Magnesium (NiSiMg) as the negative leg. It is designed for temperature measurements in high-temperature environments, offering a wide operational range from -200°C to 1300°C, making it suitable for a variety of industrial and scientific applications.
Type N thermocouples are known for their exceptional stability and resistance to oxidation, especially at elevated temperatures. This makes them ideal for use in high-temperature furnaces, kilns, and other demanding environments where consistent, long-term performance is required. Additionally, Type N thermocouples are less prone to drift compared to other high-temperature thermocouples, such as Type K, and they offer excellent resistance to thermoelectric instability, ensuring more accurate and reliable temperature readings over time.
Applications of NiCrSi-NiSiMg Type N thermocouple wire include industries like metal processing, heat treatment, aerospace, and power generation, as well as scientific research where high-temperature measurements are critical. Its durability and accuracy at high temperatures make it a preferred choice for precision temperature monitoring in harsh conditions.
