Automation Applications of Thermopile Arrays

For a temperature difference occurring between two ends of a thermocouple, it develops an electrical voltage difference. A series of such thermocouples form a thermopile sensor, with each element being a thin wire made from two materials differing in the thermal activity. All the hot junctions of the thermocouples are placed on a thin common absorbing area that forms the sensor face, while the cold junctions are placed on a heat sink with a high thermal mass. As an instrument, the thermopile sensor Read more [...]
