Thermopiles

Thermopiles are temperature sensors comprised of interconnected thermocouples, typically made of two dissimilar metals. These devices generate an electrical voltage in response to temperature variations across their junctions. As temperature changes, the voltage produced by the thermopile is proportional to the temperature difference, enabling precise thermal measurements. Commonly used in infrared thermometers and gas boilers, thermopiles exploit the Seebeck effect, where temperature gradients induce electron flow between the thermocouple materials. This generates a measurable output, providing a reliable method for non-contact temperature sensing in various industrial and consumer applications.
