Webb12 jan. 2024 · The thermocouple is an electrical device containing junctions of two dissimilar metal joints. It is used as temperature sensors. It works on the principle of thermoelectric effect or Seebeck effect which states that temperature difference between two dissimilar electric conductors produces a voltage difference between them.

WebbThe thermopile is nothing but thermocouples connected in series or parallel. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which gets displayed on the screen.
