ISO9001 NiCr-NiSi Thermocouple Extension Wire Type K For Temperature Detection Element
NiCr-NiSi Thermocouple Extension Wire, commonly referred to as Type K, is designed to extend the signal of Type K thermocouples, which are known for their high-temperature capabilities and accuracy. Made of nickel-chromium (NiCr) and nickel-silicon (NiSi) alloys, Type K extension wire maintains compatibility with Type K thermocouples, ensuring accurate and reliable signal transmission over distances without introducing significant measurement errors.
Type K thermocouples are popular in industries such as aerospace, metalworking, and power generation due to their ability to withstand high temperatures (up to approximately 1,260°C or 2,300°F). The extension wire allows temperature readings to be accurately transmitted from the sensor to control or monitoring systems, even in harsh environments, without loss of precision.
NiCr-NiSi Type K extension wire also provides durability, corrosion resistance, and thermal stability, making it suitable for challenging industrial applications. This wire is commonly insulated with materials that protect against environmental hazards and mechanical stress, further enhancing its lifespan and performance. In summary, NiCr-NiSi Thermocouple Extension Wire Type K is an essential component for maintaining the accuracy and durability of high-temperature thermocouple systems across various industries.
