The document discusses thermocouples, which are electrical devices that consist of two dissimilar electrical conductors forming a junction. Thermocouples are widely used as temperature sensors across various industrial and scientific applications by functioning based on the Seebeck, Peltier, and Thompson effects. The document outlines the working principle of thermocouples and discusses their types, applications in industries like food, and advantages and disadvantages.
