Industrial thermocouples include platinum rhodium wire B type, S type, and R type.
Platinum rhodium thermocouples, also known as high-temperature precious metal thermocouples, can be divided into single platinum rhodium (platinum rhodium 10 -platinum ) and double platinum rhodium (platinum rhodium 30- platinum rhodium 6).
They serve as temperature measurement sensors and are usually used in conjunction with temperature transmitters, regulators, and display instruments to form a process control system for directly measuring or controlling fluids within the 0-1800 ºC range in various production processes Temperature of steam and gas media, as well as solid surfaces.
Tankii's S type thermocouple wire Advantages: Platinum rhodium wire has the highest accuracy, best stability, wide temperature range for temperature measurement, long service life, and high upper limit for temperature measurement in the thermocouple series.
Tankii Thermocouple wires are selected based on the temperature range, accuracy, and environmental conditions of the application.
Thermocouple wires are commonly used in industries such as manufacturing, HVAC, and scientific research.
Platinum Rhodium Alloys with more than 20% Rh are insoluble in aqua regia. Mainly used as thermocouple materials, such as PtRh10/Pt, PtRh13/Pt, etc.,used as thermocouple wires in thermocouples to directly measure or control the temperature of fluids, steam, gas media, and solid surfaces within the range of 0-1800 ºC in various production processes.
