Tungsten-Rhenium Thermocouples T5R and T3R Series - 1

UA-17 www.omega.co.uk +44 (0)161 777 6611 ® Unsheathed Fine Diameter Tungsten-Rhenium Thermocouples Tungsten-Rhenium thermocouples were developed to meet the requirements for measuring ultra-high temperatures in the 2760°C (5000°F) range. OMEGA makes available two widely used Tungsten- Rhenium thermocouple calibrations. Tungsten-5% Rhenium versus Tungsten-26% Rhenium and Tungsten- 3% Rhenium versus Tungsten-25% Rhenium. OMEGA® Tungsten-Rhenium Thermocouples conform to the limits of error listed in the Table: “Limits of Error for Tungsten-Rhenium Thermocouple Wire combinations.” 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. Wire Diameter mm (in.)

Series - Will measure and control temperatures with Type C thermocouples See OB-Series of OMEGABOND® Cementsin Section F. See page A-147 for Ceramic Insulators. iSeries meters and controllers, shown smaller than actual size, are featured in Sections M and P. ** Tungsten-Rhenium alloy thermocouples are supplied in standard 300 mm (12") lengths (600 mm [24"] loops). Change suffix “-12” in model number to indicate additional length (in inches) required. Consult Sales for other sizes.

Both thermocouple calibrations can be used to 2760°C (5000°F) 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 (12") lengths which corresponds to each for a 600 mm (24") total length. Longer lead lengths are available, Consult Sales.
