What Is a Thermocouple? Temperature Measurement in Industrial Processes

Introduction

Thermocouples are widely used temperature sensors in industrial plants.

They are valued for their durability, fast response, and ability to measure high temperatures.

What Is a Thermocouple?

A thermocouple is a temperature sensor made from two different metal wires joined together.

When the junction experiences temperature changes, a small voltage is generated that corresponds to the temperature.

Advantages of Thermocouples

Wide temperature range
Fast response time
High durability

Applications

Thermocouples are commonly used in:

Furnaces
Boilers
Heat exchangers
Chemical processes

Conclusion

Thermocouples are reliable temperature sensors widely used in industrial instrumentation systems.
