Application and Performance Data for Tungsten-Rhenium Alloy Thermocouples 630350
The present status of temperature measurement using W/W-26% Re and W-5%, Re/W-26% Re is described. The availability of these materials is discussed with respect to quantity and quality. A discussion of field and fabrication problems and methods is presented, and precautions are outlined. Performance in a variety of applications of bare wire and swaged construction thermocouples is evaluated and data are presented. The present status of these thermocouple materials with respect to availability, calibration control, fabrication of sheathed constructions, application problems, and emf stability after high temperature service are reviewed.
