Uninsulated Refractory Metal Thermocouple Wire
Tungsten-rhenium thermocouple alloy combinations were developed to meet the need for measuring ultra-high temperatures in the 2315°C (4200°F) range.
OMEGA sells 3 widely used tungsten-rhenium thermocouple alloy combinations:
Type G: Tungsten (+) vs. Tungsten 26% rhenium (–)
Type C: Tungsten 5% rhenium (+) vs. Tungsten 26% rhenium (–)
Type D: Tungsten 3% rhenium (+) vs. Tungsten 25% rhenium (–)
To guarantee the limits of error, OMEGA thermocouple wire only in matched pairs by the double foot. Because of the inherent brittleness of unalloyed tungsten, rhenium has been added to the positive leg of types C and D to improve handling characteristics. The average emf of types C and D is slightly less than that of the unalloyed type G.
All 3 thermocouple combinations can be used to 4200°F (2315°C) in hydrogen or inert-gas atmospheres and in a vacuum. They deteriorate rapidly under oxidizing conditions and should not be used in air or atmospheres containing oxygen.
For other wire sizes and large quantities, consult the Special Quotations department.
