termoküüned

Termoküüned, also known as thermocouples, are sensors used to measure temperature. They consist of two different types of metals joined at one end, forming a junction. When there is a temperature difference between the junction and the other ends of the metals, a voltage is generated, which can be measured and converted into a temperature reading. This principle is based on the Seebeck effect, discovered by Thomas Johann Seebeck in 1821.

Thermocouples are widely used in various industries due to their simplicity, robustness, and wide temperature measurement range. They can measure temperatures from cryogenic levels up to several thousand degrees Celsius. Common types of thermocouples include Type K, Type J, and Type T, each with its own unique temperature range and metal composition.

One of the main advantages of thermocouples is their ability to measure temperature directly at the point of interest, making them ideal for applications where other types of temperature sensors may not be suitable. They are also relatively inexpensive and can be used in harsh environments.

However, thermocouples do have some limitations. They require a reference junction compensation to accurately measure temperature, and their accuracy can be affected by the presence of electromagnetic interference. Additionally, thermocouples are not suitable for applications requiring very high precision or rapid response times.

In summary, thermocouples are versatile and reliable temperature sensors that have been widely adopted in various industries. Their ability to measure temperature directly at the point of interest, along with their robustness and wide temperature measurement range, makes them a popular choice for temperature measurement applications.
