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 … Meer weergeven 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. … Meer weergeven 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 … Meer weergeven • Heat flux sensor • Bolometer • Giuseppe Domenico Botto • Thermistor Meer weergeven Thermocouples ideally should be very simple measurement devices, with each type being characterized by a precise $${\displaystyle \scriptstyle E(T)}$$ curve, independent … Meer weergeven Certain combinations of alloys have become popular as industry standards. Selection of the combination is driven by cost, availability, convenience, melting point, chemical properties, stability, and output.
