Isotech Thermocouple Standards Platinum/Palladium
- Superior stability to Platinum / Platinum Rhodium
- Very Low Uncertainties
- Temperature Range 0 to 1500°C
Isotech Thermocouple Standards Platinum/Palladium
The Isotech Thermocouple Standards Platinum/Palladium (Pt/Pd) are manufactured by the National Physical Laboratory (NPL), which developed a new physical mechanism for relieving the mechanical stress caused by the difference in thermal expansion of Pt – wires and Pd – wires. This eliminates the fragile coil usually used with this type of thermocouple.
Platinum/Palladium thermocouples are more expensive than Platinum/Platinum rhodium types but benefit from superior performance in both stability (less calibration) and accuracy. Gold and Platinum (Au/Pt) thermocouples offer the best performance but are limited to a maximum temperature of 1000°C. These Pt/Pd thermocouples have a lower drift than Platinum/Platinum rhodium (Pt/Pt-Rh), with higher operating temperatures than the Gold and Platinum Au/Pt thermocouples. They are suitable for a variety of applications including transfer standards. The Isotech Platinum/Palladium (Pt/Pd) thermocouples have a temperature range up to 1500°C.
