Temperature measurement range of dual platinum rhodium thermocouple

Double platinum rhodium thermocouple is a commonly used type of thermocouple composed of platinum and rhodium metals, known for its accuracy in high-temperature measurement. The dual platinum rhodium thermocouple can measure a wide temperature range, from -270 ℃ to 1820 ℃. In addition, the linear response and high precision of the dual platinum rhodium thermocouple make it one of the most popular thermocouple types in many industrial and scientific applications.

When using a dual platinum rhodium thermocouple, it is necessary to select the corresponding model based on the temperature range to be measured. Usually, dual platinum rhodium thermocouples can be divided into three types: S, R, and B, each with different measurement ranges and accuracy levels. Among them, the measurement range of S-type double platinum rhodium thermocouple is from 0 ℃ to 1600 ℃, with an accuracy level of 0.5; The measurement range of R-type dual platinum rhodium thermocouple is from 0 ℃ to 1600 ℃, with an accuracy level of 0.5; The measurement range of B-type dual platinum rhodium thermocouple is 600 ℃ to 1820 ℃, with an accuracy level of 0.5.

In addition to the common models mentioned above, there are other types of dual platinum rhodium thermocouples available for selection to meet different application requirements. When using dual platinum rhodium thermocouples, attention should be paid to their linear response and temperature drift indicators to ensure the accuracy and reliability of measurement results.

Double platinum rhodium thermocouple is a reliable and accurate temperature measurement tool with a wide measurement range, suitable for many industrial and scientific applications. When using, it is necessary to choose the appropriate model and pay attention to its linear response and temperature drift indicators to ensure the accuracy and reliability of the measurement results.
