As its name suggests, a thermocouple is two wires of different metals joined together at one end. The other end of the thermocouple is connected to a voltmeter. When the two metals are at different temperatures, a voltage is generated between them. This voltage can be used to measure the Temperature difference between the two metals.

Thermocouples are made from a variety of different metal combinations, each with its own unique properties. The most common type of noble metal thermistor is made from copper and iron, but other combinations such as platinum and rhodium are also used in some applications.

Thermocouples have a wide range of applications due to their accuracy and versatility. They are commonly used in industrial settings to measure temperature differences in process equipment and machinery. Thermocouples are also used in scientific research and laboratories to study the effects of temperature on various materials and chemicals.

Thermocouples are devices that are used to measure temperature. They are made up of two different metals that are joined together at one end. When the two metals are at different temperatures, a voltage is created that can be measured.

There are many benefits of using a thermocouple, but the most important one is that it is the most accurate type of temperature sensor available. Thermocouples are also very rugged and can withstand high temperatures, making them ideal for use in harsh environments. Additionally, thermocouples are relatively inexpensive and easy to install.
