K-type thermocouple
Other Products
The K-type thermocouple is a widely used base metal thermocouple for industrial temperature measurement, made of nickel-chromium alloy (positive electrode) and nickel-silicon alloy (negative electrode), with a temperature measurement range from -200°C to 1300°C.
Structure and Materials
The K-type thermocouple consists of a positive electrode (KP, nickel-chromium alloy, composition Ni:Cr=90:10), a negative electrode (KN, nickel-silicon alloy, composition Ni:Si=97:3), and a protective tube, usually equipped with a terminal box for connection to display instruments.
Working Principle
Based on the thermoelectric effect principle, when two different metals are in contact and a temperature difference exists, a thermoelectromotive force proportional to the temperature difference is generated in the circuit, and the temperature is determined by measuring this potential difference.
Application Scenarios
Industrial Measurement: Used in industries such as petrochemicals, metallurgy, and ceramics to measure furnace temperatures, pipeline temperatures, etc.
Scientific Research Experiments: Temperature monitoring of high-temperature equipment in laboratories.
Daily Applications: Temperature control in devices such as ovens and radiators.
Features
Advantages: Good linearity, high sensitivity, strong oxidation resistance, low cost, suitable for oxidizing or inert environments.
Limitations: Not to be used in sulfur-containing, reducing atmospheres, or vacuum environments
