Product Description
C Type High Temperature Tungsten Molybdenum Thermocouple
WRE Tungsten Rhenium C Type Thermocouple .
This specification covers the requirements for bare, solid conductor, tungsten and rhenium alloy thermoelements having diameters of 0.13 mm (0.005 in.) to 0.5 mm (0.020 in.)supplied in matched pairs. These thermo elements is suitable for use either in bead-insulated, bare-wire thermocouples, or in compacted metal-sheathed, ceramic insulated thermocouple material or assemblies.
This specification covers the thermocouple combinations of tungsten-3 % rhenium versus tungsten-25% rhenium (W3RE/W25RE) and tungsten-5 % rhenium versus tungsten-26 % rhenium (W5RE/W26RE). All information applies to both combinations unless otherwise noted.
Specifications:
1) Compositions:
a) Positive (+): 97% tungsten, 3% rhenium
b) Negative (-): 75% tungsten, 25% rhenium
2) Diameter: 0.5mm, as per customers' requests
3) Working temperature: 0 - 2,300oC
4) Tolerances:
a) 0 to 400oC: ± 4oC
b) 400 to 2,300oC: ±0.5%
Choose types from following table
Alloy Combination | Tolerance Class | Temp Range | Diameter | Environment Bare wire | |
+Lead | -lead | Grade | |||
Tungsten-5%Rhenium (W-5%Re) | Tungsten-26%Rhenium | I | 0-2300 | 0.08-0.5 | Vacuum, |
II | 0-2300 | ||||
Tungsten-3%Rhenium | Tungsten-25%Rhenium | I | 0-2300 | 0.08-0.5 | Vacuum, |
II | 0-2300 | ||||
A purchase order for thermocouple material conforming to this specification should specify the following:
1: Thermocouple Wire Composition_ May be doped TungstenRhenium3/TungstenRhenium25 or doped TungstenRhenium5/TungstenRhenium26.
1.2: Wire Size_Specify size with each order.
1.3: Wire Length_Specify total amount of each wire and minimum continuous length.
1.4: Thermocouple Calibration_Paired wires is furnished to the initial calibration tolerances
1.5: Required Mechanical Properties
1.6 Instructions for Spooling, Packaging, and Labeling_Wires is supplied on spools of a nominal 100 mm (4-in.)diameter core and boxed individually, unless otherwise requested.
Each spool is marked to identify the wire composition, diameter, quantity, processor's name, spool designation and customers purchase order number in a manner to identify the pair of wires to be used to form a thermocouple meeting the calibration requirement.
1.7 Tests and Certifications Required from the Processor_Unless otherwise requested, the processor supply a certificate with each order stating the wire composition, size and calibration information.
Special sizes are available, please contact sales for inquiries.
