Product Details

Product Overview

K type thermocouple sensor usually used in conjunction with display instruments, recording instruments, and electronic computers. Directly measure the surface temperature of liquid, steam and gaseous media and solids in the range of 0 degrees to 1300 degrees in various production processes.

Nickel-chromium-nickel-silicon thermocouple (K-type thermocouple) is currently the largest amount of low-cost metal thermocouple, and its amount is the sum of other thermocouples. 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, and its operating temperature is -200~1300℃.
K type temperature thermocouple has the advantages of good linearity, large thermoelectromotive force, high sensitivity, good stability and uniformity, strong oxidation resistance, and low price. It can be used in oxidizing inert atmosphere. Widely adopted by users.

K-type thermocouples sensor cannot be directly used in sulfur, reducing or reducing, oxidizing alternate atmospheres and vacuum at high temperatures, nor are they recommended for use in weakly oxidizing atmospheres.
