Explore the characteristics and applications of armored thermocouples

The armored thermocouple is a sensor widely used for temperature measurement. It consists of two different metal wires (usually copper and copper-nickel alloy) that form a joint when the ends are connected, which is called a thermocouple joint. The temperature difference at the thermocouple joint generates a thermoelectric potential, from which the measured temperature can be calculated.

Compared with other types of thermocouples, armored thermocouples have higher anti-interference ability and larger measurement range. Its outer layer is usually covered by a protective sleeve made of metal tube or steel wire, which can effectively prevent mechanical damage and electromagnetic interference, allowing it to work normally in harsh environments.

In addition, armored thermocouples also have high accuracy and reliability, so they are widely used in various industrial fields. It can be used in high and low temperature environments, such as heat treatment processes and heat source monitoring in industries such as petrochemicals, metallurgy, and power. In addition, armored thermocouples can also be used in thermopile power generation to convert waste heat into electrical energy.

However, the following points should be noted when using armored thermocouples. First, make sure that the joint is firmly connected and the surface of the sleeve is clean and smooth to better conduct the temperature. Secondly, appropriate models and specifications, as well as appropriate measurement methods should be selected according to actual conditions. Finally, armored thermocouples should be calibrated and maintained regularly during use to ensure their accuracy and reliability.
In short, armored thermocouples are a very important industrial measurement sensor with high anti-interference ability, wide measurement range, high accuracy, and good reliability. The reasonable use and maintenance of armored thermocouples in the production process plays a very critical role in improving production efficiency and ensuring product quality.
