WebbJoseph Wu ABSTRACT Thermocouples are common temperature sensors used in a wide variety of commercial and industrial applications. While slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range, are self-powered, and have a fast response time. 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 measure … Visa mer 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 … Visa mer Wires insulation The wires that make up the thermocouple must be insulated from each other everywhere, except at the sensing junction. Any … Visa mer 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 measurement for kilns, gas turbine exhaust, diesel engines, other industrial processes … Visa mer 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 … Visa mer 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.
