What is a Thermocouple?

• A thermocouple is a type of transducer that converts thermal energy into electrical energy. It is made by joining wires of dissimilar metals to create a junction. When the temperature at this junction changes, it generates a voltage that can be measured and used to determine the temperature.
• The thermocouple operates based on the Seebeck Effect, which states that when dissimilar metals are joined at a junction, they generate a small, measurable voltage in response to changes in the temperature at that junction. The magnitude of the voltage produced depends on both the temperature change and the properties of the metals used.
• A thermocouple is composed of two insulated wires made from different metals, which are connected to a measuring device. It functions as a safety and monitoring tool for various processes and equipment, providing crucial temperature measurements and ensuring proper operation.
• The operation of a thermocouple is illustrated in the image below. As the temperature increases at the junction of the wires on the left, the resulting temperature change is displayed on the gauge on the right.
• Thermocouple assemblies are engineered for use in harsh, severe, and demanding environments. The selection of a thermocouple depends on factors such as the temperature range, ambient atmosphere, and the type of media being measured. Additionally, the size and shape of the thermocouple are tailored to the specific application, considering factors like required accuracy and response speed.

How Does a Thermocouple Work?

In a thermocouple, the two wires are joined to form a junction where one wire, connected to the body of the thermocouple, acts as the hot or measuring junction that measures the temperature. The other wire connects to a reference junction, also known as the cold junction, which is kept at a known temperature. The thermocouple determines the unknown temperature by comparing the voltage generated at the hot junction with the reference temperature at the cold junction.

Using a Thermowell

A thermowell is designed to protect a thermocouple from process media by encasing it in a closed tube or solid bar-stock that is mounted within the media. Thermowells are commonly used with fluids and pressure lines in refineries and chemical plants to extend the life of thermocouples. They facilitate the replacement of a thermocouple without requiring a process shutdown.
