Type S/B/R Platinum Rhodium Thermocouple With Ceramic Protection Tube

产品描述

Platinum Rhodium Thermocouples have the highest accuracy, best stability, wide temperature range, long service life and high temperature limit in the thermocouple series. It is suitable for use in oxidizing and inert atmospheres. It can also be used in vacuum for a short period of time, but it is not suitable for use in reducing atmospheres or in metal or non-metal vapor atmospheres. An obvious advantage of the Type B thermocouple is that it does not require compensation with a compensation wire, because the thermal electric potential is less than 3 μV in the range of 0 到 50 °C.Platinum-rhodium thermocouples work on the principle that when a platinum-rhodium thermocouple is joined by a conductor of two different components, when the temperature of the two junctions is different, a thermal current is generated in the loop. If there is a temperature difference between the working end of the thermocouple and the reference junction, the display meter will indicate the temperature value corresponding to the thermal electric potential generated by the thermocouple.Platinum rhodium thermocouple selection: It is recommended to use a single platinum rhodium thermocouple (platinum rhodium 10-platinum) when the measured temperature is normal at 1000~1300 °C. It is recommended to use a double platinum rhodium thermocouple when the measured temperature is normal at 1200~1600 °C. Platinum rhodium 30-platinum rhodium 6), so that the lifetime of the platinum rhodium thermocouple can be guaranteed within the temperature range used.
