Tankii S type B type R type noble metal thermocouple wire
Product Description
Platinum rhodium wire is a platinum based binary alloy containing rhodium, which is a continuous solid solution at high temperatures.
Rhodium can improve the thermoelectric potential, oxidation resistance, and acid corrosion resistance of alloys to platinum.
There are alloys such as PtRh5, PtRh10, PtRh13, PtRh30, and PtRh40.
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.
Type R, S, and B thermocouple wires are "Noble Metal" thermocouples, which are used in high temperature applications.
Type S thermocouple wires are characterized by a high degree of chemical inertness and stability at high temperatures. Often used as a standard for calibration of base metal thermocouples
Platinum rhodium thermocouple wire (S/B/R TYPE)
Platinum Rhodium Assembling Type Thermocouple wire is widely used in production places with high temperature.
It is mainly used to measure temperature in glass and ceramic industry and industrial salting
Insulation material: PVC, PTFE, FB or as per the customer's requirement.
Application of thermocouple wire
• Heating - Gas burners for ovens
• Cooling - Freezers
• Engine protection - Temperatures and surface temperatures
• High temperature control - Iron casting
