K-Type Thermocouple Wire Nickel Chromium Nickel Silicon Thermocouple Wire

Introduction:

K-type thermocouple bare wire is a commonly used thermocouple type, consisting of K-type thermocouple alloy exposed wires. The alloy composition of K-type thermocouple is nickel-chromium/nickel-aluminum, and the common materials are KP and KN. Type K thermocouple bare wire has a wide operating temperature range and is typically used in temperatures ranging from -200°C to 1,370°C.

K-type thermocouple bare wire has many advantages, such as good linear characteristics, higher sensitivity and lower price. Nickel-chromium-nickel silicon thermocouple (K-type thermocouple) is currently the most widely used cheap metal thermocouple in temperature measurement areas above 500°C, and its usage is the sum of other metal thermocouples. They are widely used in industry, especially in temperature measurement and control. K-type thermocouple bare wire has a fast response speed and is suitable for applications requiring fast temperature response.
The nominal chemical composition of the positive electrode (KP) is: Ni:Cr≈90:10
The chemical composition of the negative electrode (KN) is: Ni:Si≈97:3
