Characteristic functions for high-temperature thermocouple types, showing Pt/Rh, W/Re, Pt/Mo, and Ir/Rh-alloy thermocouples. Also shown is the Pt–Pd pure-metal thermocouple. Types B, R, and S thermocouples use platinum or a platinum/rhodium alloy for each conductor. These are among the most stable … See more 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 … 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 other details. In reality, thermocouples are affected by issues such as alloy … See more Wires insulation The wires that make up the thermocouple must be insulated from each other everywhere, except at the sensing junction. Any … See more • Heat flux sensor • Bolometer • Giuseppe Domenico Botto 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 time, Seebeck referred to this consequence … 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 WebThermocouples of a given type may have variations in composition as long as their resultant temperature-voltage relationships remain within specified tolerances.
