Tungsten-Rhenium thermocouples were developed to meet the requirements for measuring ultra-high temperatures in the 2760°C (5000°F) range.

OMEGA makes available three widely used Tungsten-Rhenium thermocouple calibrations. Tungsten versus Tungsten-26% Rhenium, 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.”

Because of the inherent brittleness of unalloyed Tungsten, the Tungsten versus Tungsten-26% Rhenium thermocouples are more difficult to handle than the Tungsten-5% Rhenium versus Tungsten-26% Rhenium combination.

The average EMF of the W-3% Re/W-25% Re is slightly less than that of W/W-26% Re and 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.

All three 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 oxidizing conditions and should not be used in air or atmospheres containing oxygen.

OMEGA® Tungsten-Rhenium thermocouples are supplied in 12-inch lengths which corresponds to each leg for a 24" total length. Longer lead lengths are available, Consult Sales.

* Most popular of the three Tungsten-Rhenium thermocouples, a large selection of instrumentation is available.
** Tungsten-Rhenium alloy thermocouples are supplied in standard 300 mm (12") lengths, which corresponds to each leg for a 600 mm (24") total length. Change suffix “-12” in model number to indicate additional length required in inches.
NOTE: Butt-Welded Tungsten-Rhenium thermocouples cannot be bent in the butt-welded area. All warranties are voided if the customer chooses to bend the thermocouple.
