What is an R-type thermocouple?

An R-type thermocouple is a temperature sensor made from a platinum-rhodium alloy, allowing it to operate at extremely high temperatures with high stability and minimal thermal drift.

This R-type thermocouple is used in processes where accuracy and resistance to oxidation are essential, such as in high-temperature furnaces, laboratories, and advanced industrial processes. Its composition makes it ideal for applications that require reliable measurements over the long term.

How does an R-type sensor work?

The type R sensor works by generating an electrical signal proportional to the temperature difference between its ends. Made of noble metals such as platinum and rhodium, it offers high measurement stability and high resistance to degradation in harsh environments.

Thanks to its ability to operate in extreme conditions without losing accuracy, the R-type thermocouple is widely used in applications where rigorous and reliable thermal control is required.

Measurement range of a type R thermocouple

The measuring range of the type R thermocouple is approximately 0°C to 1,600°C, with excellent stability across its entire spectrum.

Unlike other thermocouples, its ability to operate at high temperatures with minimal drift makes it a preferred choice for demanding applications. Additionally, its resistance to oxidation and chemical contamination ensures accurate readings over long periods of use.

How to choose the right type R thermocouple sensor?

To select the ideal type R thermocouple sensor, it is essential to consider the working environment, the required temperature range, and the type of insulation needed. Some key points to evaluate include:

  • Maximum operating temperature: Ensure that the R-type sensor covers the thermal range required for the application.

  • Protective material: Determines the durability and resistance of the sensor in aggressive environments.

  • Probe configuration: Depending on the application, different types of R-type temperature probes can be selected to optimise measurement accuracy and stability.
