High temperature thermocouples are mostly used in high heat industrial fabrication processes in applications where standard thermocouples would fail or get damaged. They have the highest temperature resistance and range, fare well in severe environments and have maximum temperatures of around 2,300ºC.

High temperature thermocouples always have vertical assembly so they will not bend under their own weight in high temperature environments. Thermocouples are one of the most widely used types of sensors due to their ability to be used in a wide range of applications. They are used in exhaust gas, power turbine, compressor discharge, brake system, bearings and hydraulic oil applications. Thermocouple instruments also measure and monitor temperatures in heat treatments and combustion processes and hot gas environments. Forgeries, foundries and metal fabrication mills also employ high temperature thermocouples for drawing, casting and extruding different metals, especially iron and steel, which require high amounts of heat in order to melt. Thermocouple instruments are rigid in construction and design, highly reliable and are used in many different applications within the metal fabrication, glass and ceramics industries to monitor temperatures. High temperature thermocouples are always protected against contamination, corrosive and abrasive ambient influences and exposure to molten substances.
All high temperature thermocouples are made out of precious or platinum metals and include type K, B, R, S, C and N. Thermocouples are a cheap component to heat measurement systems and are able to prevent damage and malfunctions in equipment due to excessive high temperatures. All thermocouples designed for high temperature applications use refractory metals and contain a coating of material with a high melting point. While the most common metal for high temperature thermocouple insulation is high grade 99.4% + purity magnesium oxide, berylia oxide, hafina oxide and aluminum oxide are all used as well. The sheaths are always made of strong, resistant and high temperature metals like titanium, tungsten and tantalum. Once assembled, the thermocouple wire is always pre-heated before installation. This prevents the damage of the ceramic protection tubes. Like all thermocouples, those designed for high temperature applications and environments are composed of two different wires, each of which is made of a different metal alloy. The wires are contained in a sheath together or in separate sheaths, which are made of high grade, resistant metals. Electrical current flows through the wires when the two ends are different temperatures. The voltage is then measured, which determines the exact temperature difference.
