Introduction:
Armored thermocouple is a sensor used for temperature measurement and control, with a wide range of applications and important functions. The basic principle of armored thermocouples is to use the thermoelectric effect of two different metal wires to measure temperature changes and convert them into corresponding voltage signals.
It has the characteristics of fast response, wide temperature range, high accuracy and stability, and plays an important role in industry, scientific research and other fields.
There are some key factors to consider when selecting an armored thermocouple. The first is the temperature range. Select the appropriate model based on specific application needs to ensure normal operation within the target temperature range. The second is the material of the protective sleeve, which needs to have properties such as high temperature resistance, corrosion resistance and mechanical strength to protect the wires of the armored thermocouple from the external environment. In addition, factors such as the size, response time, and connection method of the armored thermocouple need to be considered.
In summary, the armored thermocouple is a sensor widely used in the field of temperature measurement and control. It has the advantages of fast response, wide temperature range, high accuracy and stability, and plays an important role in industry, scientific research and various other fields. Choosing the right armored thermocouple can meet the needs of a specific application and provide an accurate and reliable temperature measurement solution.

Q&A:
What are the advantages of armored thermocouples over other temperature sensors?
Armored thermocouples have the advantages of fast response, high measurement accuracy and high durability. Compared to other temperature sensors, armored thermocouples provide accurate and reliable temperature measurements over a wide temperature range.
How to calibrate armored thermocouples?
Calibration of sheathed thermocouples is usually performed by exposing them to a calibration source of known temperature. Based on the calibration results, the relationship between temperature and potential difference can be established to obtain accurate temperature measurements.
What temperature ranges are armored thermocouples suitable for?
Armored thermocouples are available over a wide temperature range. Different types of armored thermocouples have different temperature range adaptability. For example, Type K thermocouple is suitable for the range of -200°C to 1,300°C, while Type J thermocouple is suitable for the range of -210°C to 760°C. . The specific selection of the appropriate type of armored thermocouple depends on the temperature range to be measured and the requirements of the application environment.
