Super OMEGACLAD[[®]] XL sheathed mineral-insulated thermocouple wire, designated “XL” for ordering, can be used at high temperatures for prolonged periods with very little drift of the base metal thermocouple. The sheath material uses NickelChrome based Super OMEGACLAD XL sheathing, which provides excellent oxidation resistance. The sheath can withstand long-term exposure to combustion gases or air at temperatures up to 1150°C (2102°F). Short-term exposures to higher temperatures are also possible. Superior resistance to oxidation attack results from a tenacious and protective high temperature film that does not affect the stability of the thermocouple alloys. This film permits the sensor to be used at ultra-high temperatures for prolonged periods with improved accuracy over other available sheath materials. Super OMEGACLAD XL sheathing also provides excellent resistance to corrosion in high temperature chlorinecontaminated oxidizing environments and ammonia/nitride-rich environments at temperatures above 980°C (1800°F), the temperature at which the protective film forms.
