The temperature measurement principle of the armored thermocouple is based on the thermoelectric effect, in which two different metal wires generate a thermoelectric potential difference through the thermoelectric effect, and the temperature is determined by measuring the thermoelectric potential difference.
In laboratory applications, the selection of armored thermocouples should be based on experimental conditions, requirements and measurement ranges. Different armoring materials and specifications are suitable for different experimental environments and temperature ranges.
Armored thermocouples can be used with temperature measuring instruments (such as thermometers, data acquisition systems) to obtain and record temperature data.
When using armored thermocouples for temperature measurement, attention needs to be paid to protecting the armored cable from mechanical damage or environmental corrosion to ensure the accuracy and reliability of the measurement.
Armored thermocouples may encounter some limitations and challenges in some special application areas (such as high-temperature molten metal, high-pressure environments, etc.), so the actual situation needs to be considered comprehensively when selecting and using them.
In short, as a common temperature measurement device, armored thermocouples have extensive applications and important roles in scientific research and laboratory applications. By measuring temperature, they provide important data support for researchers and promote various Scientific progress and technological innovation in the field.
