In recent decades, thermocouple thermometers have been inseparable in fields like manufacturing and research, and also in healthcare and food processing. The unique capability for the measurement of temperature with high accuracy, even in very aggressive environments, has made it versatile for many applications. This blog deepens your understanding of what a thermocouple thermometer is, how it works, its types, advantages, and practical applications.
What is a thermocouple thermometer?
A thermocouple thermometer is a temperature measuring device that utilizes a thermocouple as the sensor element. Thermocouples are basically composed of two dissimilar metals joined at one end, known as a junction. There exists an electromotive force (EMF) across a junction when there is a temperature difference between the hot and cold ends of this junction. This EMF gets converted into a reading of temperature.
Probably among these, thermocouple thermometers work effectively in a wide measurement range, have a fast response, and are able to accept external harsh conditions, making it suitable for industrial, scientific, and commercial applications.
How Do Thermocouple Thermometers Work?
The operating principle of the thermocouple thermometer is that of the Seebeck effect. It states that when a juncture of two different metals is subjected to differential temperature, then a corresponding voltage will be generated in the said juncture and is directly related to this temperature difference; thus, with appropriate calibration, one can determine the actual temperature.
The key components include:
- Hot Junction: Located in the medium whose temperature needs to be measured.
- Cold Junction: Kept at an already known reference temperature.
- Output Device: The device that converts voltage into a readable temperature value.
