About this product:

Thermocouples are widely used temperature sensors that operate on the principle of thermoelectricity. They consist of two dissimilar metal wires joined at one end, where a voltage is generated that corresponds to the temperature difference between the junction and the other ends of the wires. Here are some key points and notes on the use of thermocouples:

Principle of Operation

Seebeck Effect: The basic operating principle of thermocouples is the Seebeck effect, where a voltage is generated when there is a temperature difference between the junction (hot junction) and the reference end (cold junction).

Voltage Output: The generated voltage is proportional to the temperature difference, allowing for temperature measurement.

Types of Thermocouples

Common Types:

Type K (Chromel-Alumel): Wide temperature range (-200°C to 1260°C), good for general-purpose applications.

Type J (Iron-Constantan): Limited range (-40°C to 750°C), suitable for lower temperatures.

Type T (Copper-Constantan): Good for cryogenics and low-temperature applications (-200°C to 350°C).

Type E (Chromel-Constantan): Good sensitivity and a range (-200°C to 900°C).

Type N (Nicrosil-Nisil): Stable for high temperatures (up to 1300°C) and suitable for harsh environments.

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.
