Definition and function of armored thermocouple

Armored thermocouple is a sensor used for measuring temperature. It consists of two wires made of different metals covered by an insulating sheath, one of which is commonly used copper, while the other metal is selected from different materials based on the required temperature measurement range, such as chromium aluminum, nickel chromium, etc. The function of a thermocouple is to measure the temperature of the object being measured based on the principle of thermoelectric effect.

When the temperature of the object being measured changes, the temperature of the wire also changes, resulting in a thermoelectric potential difference. By measuring this thermoelectric potential difference, it can be converted into a corresponding temperature value. The advantages of armored thermocouples include good seismic resistance, wide measurement range, and long service life, so they are widely used in the field of temperature measurement in industrial production processes. Armored thermocouples can operate stably and reliably in high, low, and harsh environments.

Armored thermocouples play an important role in industries such as aerospace, chemical, and steel. By measuring temperature, armored thermocouples can help enterprises save energy, improve production efficiency, and ensure product quality during the production process. It not only has good performance in measuring temperature, but also has a very fast response speed during temperature changes, which can provide accurate temperature values in a timely manner and help engineers adjust production parameters in a timely manner, thereby achieving * * control of production. The emergence of armored thermocouples provides a reliable and high-precision temperature measurement method for industrial production, greatly promoting the development of industrial automation.
