K-type thermocouple
3 week ago
K-type thermocouple is the most widely used and cheap metal thermocouple. Its full name is nickel-chromium-nickel-silicon thermocouple, which is composed of positive nickel-chromium alloy (NiCr) and negative nickel-silicon alloy (NiSi). It can convert temperature signals into thermoelectric potential signals, determine the temperature of the object being measured by measuring thermoelectric potential, has good linearity and sensitivity, and provides accurate and reliable temperature data for various temperature measurement scenarios.
Performance characteristics
Wide temperature measurement range: The measurable temperature range is extremely wide, usually between -200℃ and 1300℃, which can meet the measurement needs under various temperature conditions from ultra-low temperature environment to high-temperature industrial production, such as high-temperature smelting process in metallurgical industry and low-temperature testing in refrigeration industry.
High-precision measurement: It has high measurement accuracy. Within the common industrial temperature measurement range, it can accurately reflect temperature changes, and the error can be controlled within a small range, providing strong support for precise control of production processes and accurate data collection for scientific research.
Fast response speed: It reacts quickly to temperature changes, can sense temperature fluctuations in a short time and output corresponding thermoelectric potential signals. It has strong real-time performance and can timely feedback temperature changes. It is suitable for occasions where temperature data needs to be obtained quickly, such as temperature monitoring of rapid heating or cooling processes.
Good stability and durability: The nickel-chromium and nickel-silicon alloy materials used have good oxidation resistance and corrosion resistance. They can work stably for a long time in general industrial environments and atmospheric conditions, are not easily affected by environmental factors and cause performance degradation, have a long service life, and reduce the cost and trouble of frequent replacement.
Good linearity: There is a good linear relationship between the output thermoelectric potential and temperature, which is convenient for data processing and analysis. In temperature measurement and control systems, it can more conveniently calculate and control temperature, and improve the accuracy and reliability of the system.
Economical and affordable: As a low-cost metal thermocouple, the manufacturing cost of the K-type thermocouple is relatively low and the price is relatively affordable. While meeting most conventional temperature measurement needs, it provides users with a cost-effective option and is widely used in various industrial and civil fields.
