A thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction. A thermocouple produces a temperature-dependent voltage as a result of the Seebeck effect, and this voltage can be interpreted to … See more In 1821, the German physicist Thomas Johann Seebeck discovered that a magnetic needle held near a circuit made up of two dissimilar metals got deflected when one of the dissimilar metal junctions was heated. At the … See more Wires insulation The wires that make up the thermocouple must be insulated from each other everywhere, except at the sensing junction. Any additional electrical contact between the wires, or contact of a wire to other conductive … See more • Heat flux sensor • Bolometer • Giuseppe Domenico Botto • Thermistor • Thermoelectric power See more Thermocouples ideally should be very simple measurement devices, with each type being characterized by a precise Circuit construction See more Certain combinations of alloys have become popular as industry standards.
