Overview of K-type thermocouple wires
summary
As a temperature sensor, K-type thermocouple is usually used in conjunction with display instruments, recording instruments, and electronic regulators. K-type thermocouples can directly measure the surface temperature of liquid vapor and gas media, as well as solids, ranging from 0 ℃ to 1300 ℃ in various production processes.
K-type thermocouples typically consist of temperature sensing elements, mounting fixtures, and junction boxes, among other main components.
K-type thermocouple is currently the most widely used low-cost metal thermocouple, with a usage equal to the sum of other thermocouples. The diameter of K-type thermocouple wire is generally 1.2-4.0mm.
The nominal chemical composition of the positive electrode (KP) is: Ni：Cr=90: 10. The nominal chemical composition of the negative electrode (KN) is: Ni:Si=97： 3. Its operating temperature is -200~1300 ℃.
K-type thermocouples have the advantages of good linearity, high thermoelectric potential, high sensitivity, good stability and uniformity, strong anti-oxidation performance, and low price. They can be widely used by users in oxidizing inert atmospheres.
K-type thermocouples cannot be directly used at high temperatures in sulfur, reducing or reducing oxidizing alternating atmospheres and in vacuum, nor are they recommended for weakly oxidizing atmospheres
