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 $${\displaystyle \scriptstyle E(T)}$$ curve, independent of any … See more 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. Different types are best suited for different … See more Thermocouples are suitable for measuring over a large temperature range, from −270 up to 3000 °C (for a short time, in inert atmosphere). Applications include temperature … See more • Thermocouple Operating Principle – University Of Cambridge • Thermocouple Drift – University Of Cambridge • Two Ways to Measure Temperature Using Thermocouples See more WebAside from having different usable temperature ranges, these thermocouple types also differ in terms of the atmospheres they may withstand at elevated temperatures. Type J thermocouples, for instance, by virtue of the fact that one of the wire types is iron, will rapidly corrode in any oxidizing atmosphere. Type K thermocouples are attacked by ...
