Used in vacuum or inert atmosphere applications up to 4200°F, our Type C thermocouples may be supplied with a variety of sheath options, including alumina, molybdenum and tantalum. Additional sheath coating are available to extend service life. These high-heat sensors offer an accurate temperature measurement solution for extreme temperatures.
Refractory Metal Assemblies
Description
Type “C” is one of several thermocouple wire combinations of Tungsten and Rhenium that are commonly referred to as Refractory Metals. Tungsten-5% Rhenium vs Tungsten-26% Rhenium, or Type “C”, may be used at temperatures up to 4200°F (2315°C). These Refractory metals may be used at extremely high temperature but with some constraints. Tungsten has no oxidation resistance and must be used in vacuum, hydrogen, or a totally inert gas. Type “C” thermocouples used in other atmospheres must be assembled as a sealed assembly purged with Argon.
