What Is a Thermocouple?
A thermocouple is a temperature-sensing device widely used in industrial and scientific applications. It consists of two dissimilar metal wires joined at one end to form a junction. When this junction experiences a temperature change, it generates a voltage that correlates to the temperature difference between the junction and the other ends of the wires. This phenomenon, known as the Seebeck effect, allows thermocouples to measure temperature with precision.
Thermocouples are valued for their simplicity, durability, and ability to measure a broad range of temperatures, from cryogenic levels to extreme heat. Their versatility makes them essential in industries like aerospace, manufacturing, and power generation, where accurate temperature control is crucial for efficiency and safety.
