- Abstract:
- The gold versus platinum (Au/Pt) thermocouples are very stable under long term repeated usage at higher temperature. Still there are some unsolved problems that the stress-relieving coil at the top of measuring junction is deformed after thermal cycling. In this study twist pair of thermocouple-element and U shape thin Pt wire at the measuring junction instead of the coil are tested in addition to the ordinary measuring junction. It was found that good stability and immersion characteristic is realized by a thermocouple having ordinary junction with appropriate anchoring of the thermocouple elements.
