K-type thermocouple wire is a temperature sensor composed of two different metal alloys, and its definition and core characteristics are as follows:
1. Definition
K-type thermocouple wire is the abbreviation for nickel chromium nickel aluminum (NiCr NiAl) thermocouple, which belongs to a type of base metal thermocouple. It generates thermoelectric potential through the Seebeck Effect of two different metals to measure temperature.
2. Composition
Positive electrode (KP): Nickel chromium alloy (NiCr), typically containing 90% nickel and 10% chromium.
Negative electrode (KN): Nickel aluminum alloy (NiAl), typically containing 95% nickel, 2% aluminum, 2% manganese, and 1% silicon.
3. Working principle
When the two ends of a K-type thermocouple wire are at different temperatures, a thermoelectric potential (EMF) is generated in a closed loop due to the difference in electron density between the two metals. By measuring the magnitude of the thermoelectric potential, the temperature value can be calculated.
What differentiates one thermocouple from another is the metals in its two wires: the positive leg and the negative leg. Because each thermocouple type has a different pairing, they differ in temperature limits, process conditions (inert, oxidizing, reducing atmospheres, heavy vibration), and so on.
