At Dpstar Group, we offer a quality selection of noble metal thermocouples that can endure the harshest industrial conditions. Our noble metal thermocouples are specially designed to withstand neutral, oxidizing, and reducing environments. Constructed from the highest quality materials, these thermocouples can be customized to fulfill virtually any of our customers’ application requirements.
Noble metal thermocouples excel in high temperature environments, and our models are no exception. We provide noble metal products that operate in extreme temperatures, typically ranging from 0°C to 1800°C. These noble metal thermocouples are available in Type B, R, and S, constructed from the highest quality blends of platinum and rhodium.
|Type||Names of Materials||Application Range|
|R||Platinum 13% Rhodium (+)
|0 to 1600°C|
|S||Platinum 10% Rhodium (+)
|0 to 1600°C|
|B||Platinum30% Rhodium (+)
Platinum 6% Rhodium (-)
|600 to 1600°C|
This thermocouple is made from Platinum which is the negative leg and much softer and Platinum 13% Rhodium which is the stiffer positive leg. It is suitable for use in oxidising or inert atmospheres and may be used under reducing conditions or in a vacuum provided care is taken to ensure the refractory materials are free from siliceous materials. Pure recrystallised alumina is recommended. This thermocouple is suitable for continuous use up to 1400 C and for intermittent use up to 1650 C.
This thermocouple defines the international practical temperature scale between Antimony point (630.73 C ) and the gold point (1064.43 C). This thermocouple is made from Platinum which is the negative leg and much softer and Platinum 10% Rhodium which is the stiffer positive leg, and has the same operating requirements as type R. Again This thermocouple is suitable for continuous use up to 1400 C and for intermittent use up to 1650 C.
This combination platinum thermocouple is made from Platinum-30% Rhodium and Platinum -6% Rhodium. When they are compared to pure platinum thermocouples they suffer less from the effects of ‘Rhodium migration’ and may be used at somewhat higher temperatures, continuous operating 1500 C and up to 1800 C intermittently.
We fabricate our noble metal thermocouples to the highest industrial standards, ensuring that these products provide the best longevity and at maximum levels of performance. Our noble metal thermocouples feature complete abrasion, corrosion, acid, and vibration resistance. From prototypes to full production jobs, our noble metal thermocouples maintain the highest levels of efficiency and quality.
