K type thermocouple

K-type thermocouple is a temperature sensor, K-type thermocouple and display instruments are usually used, recording instruments and supporting the use of electronic regulator.

Overview 

K-type thermocouple as a temperature sensor, K-type thermocouple and display instruments are usually used, recording instruments and supporting the use of electronic regulator. K-type thermocouples can be directly measured in a variety of production from 0 ℃ to 1300 ℃ range of liquid vapor and gas medium and solid surface temperature.

K-type thermocouple is usually composed of temperature sensing elements, mounting fixtures and junction boxes and other major components.

K-type thermocouple is currently the largest amount of cheap metal thermocouple, the amount of the sum of other thermocouples. K-type thermocouple wire diameter is generally 1.2 ~ 4.0mm.

The nominal chemical composition of the cathode (KP) is Ni: Cr = 90: 10, the nominal chemical composition of the negative electrode (KN) is: Ni: Si = 97: 3, and the working temperature is -200 ~ 1300 ℃.

K-type thermocouple has good linearity, large thermal EMF, high sensitivity, good stability and uniformity, strong oxidation resistance, low price and other advantages, can be used for oxidative inert atmosphere widely used by users.

K-type thermocouples can not be used directly at elevated temperatures in sulfur, reducing or reducing, oxidizing alternating atmospheres and in vacuum, and are not recommended for weak oxidizing atmospheres.
