Introduction:

Armored thermocouples are temperature measurement and control devices widely used in the field of industrial process control. They consist of wires of two different metals, usually a platinum-rhodium alloy and a nickel-chromium alloy. The two metal wires are connected by welding or brazing and are enclosed in a protective sleeve, usually made of stainless steel or other high-temperature-resistant material.

One of the main advantages of armored thermocouples is their adaptability and stability. They are capable of working in a wide range of industrial environments, including chemical, metallurgical, power generation, food processing and other fields. Armored thermocouples have good tolerance to high temperature environments and can stably measure and control processes at high temperatures.

When selecting an armored thermocouple, there are some key product parameters to consider. The first is the temperature range. Different types of armored thermocouples are suitable for different temperature ranges. Some models are suitable for low temperature ranges, such as -200°C to 400°C, while others are suitable for higher temperature ranges, such as 0°C to 1800°C.

Second is the material of the protective sleeve, which needs to be able to withstand high temperatures and corrosive environments. Common protective sleeve materials include stainless steel (such as 316 stainless steel), alloy steel and ceramics. Depending on the specific industrial application requirements, it is crucial to select the appropriate protective sleeve material.

Other product parameters include wire diameter, length and connector type. The choice of wire diameter depends on the required response speed and measurement accuracy. The wire length should be selected based on the actual installation location and measurement requirements. The connector type can be plug connection, threaded connection or welded connection, which needs to be determined according to the specific installation and connection method.

In summary, armored thermocouples play an important role in industrial process control. Through their stability, high temperature resistance and adaptability, they are able to accurately measure and control temperature in a variety of industrial environments. When selecting an armored thermocouple, product parameters such as temperature range, protective sleeve material, wire parameters, and connector type need to be considered to meet specific application needs.
