Thermocouple vs. Thermopile: A Complete Comparison | Linquip

2021-01-06· Thermocouple Definition. Thermocouples were first constructed after the exploration of the thermoelectric phenomenon by Thomas Johann Seebeck in 1821. Seebeck found that joining special junctions between two wires constructed from dissimilar materials produces a voltage that is proportional to the temperature variation between those junctions.
