Bare Wire, Fine Diameter Tungsten-Rhenium Thermocouples, Types C and D

• Ultra High Temperature Range up to 2325°C
• Wire diameters as Small as 0.076mm
• Type D and Type C Thermocouples
• Thermocouples supplied 300mm long as standard, other lengths available

Tungsten-Rhenium thermocouples were developed to meet the requirements for measuring ultra-high temperatures in the 2760°C range.
OMEGA™ offers two widely used Tungsten-Rhenium thermocouple types:

Tungsten-5% Rhenium versus Tungsten-26% Rhenium: Type C
Tungsten-3% Rhenium versus Tungsten-25% Rhenium: Type D

The average EMF of the W-3% Re/W-25% Re is slightly more than that of W-5% Re/W-26% Re. The ductility of W-3% Re is about equal to that of W-5%Re, but superior to that of unalloyed Tungsten.
Both thermocouple types can be used to 2760°C in hydrogen or inert gas atmospheres and in a vacuum. They undergo rapid deterioration under oxidising conditions and should not be used in air or atmospheres containing oxygen.
OMEGA™ Tungsten-Rhenium thermocouples are supplied in 300 mm lengths (600 mm loop). Longer lead lengths are available, contact our sales department.
