Butt-對焊OMEGA鎢錸合金熱電偶，微型鎢錸熱電偶，鎢錸合金裸線制成，耐溫2760°C，直徑：0.25mm (.010 inches) to 0.50mm。
Welded Unsheathed Fine Gage Tungsten-Rhenium Microtemp Thermocouples
• Designed for Measuring Ultra-high Temperatures in the 2760°C (5000°F) Range.
• Wire Diameters from 0.25mm (.010 inches) to 0.50mm (.020 inches)
• Compatible with OMEGA's DPi Panel Meters and CNi Controller Instruments
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.
