Product Description
Product Description
The working principle of the platinum rhodium thermocouple is that when the two ends of the conductor with two different components are connected to the synthetic circuit, when the temperature of the two junction points is different, the thermal current will be generated in the circuit. If there is a temperature difference between the working end and the reference end of the thermocouple, the display instrument will indicate the temperature corresponding to the thermoelectric potential generated by the thermocouple.
Platinum rhodium thermocouple in the thermocouple series has the advantages of high accuracy, good stability, wide temperature measurement range, long service life, high temperature upper limit, etc. It can be used in oxidizing and inert atmosphere, or in vacuum for a short time, but not in reducing atmosphere or atmosphere containing metal or non-metal vapor.
Selection of platinum rhodium thermocouple: it is recommended to use single platinum rhodium thermocouple (Platinum Rhodium 10 platinum) when the measured temperature is normal at 1000-1300 ºC, and double platinum rhodium thermocouple (platinum rhodium 30 platinum rhodium 6) when the measured temperature is normal at 1200-1600 ºC, so as to ensure the service life of platinum rhodium thermocouple within the temperature range used.
Type B thermocouple
Advantage: no compensation wire is needed, because the thermal potential is less than 3 μ V in the range of 0 ~ 50 ºC.
Disadvantages: the disadvantages of platinum rhodium thermocouples are thermal potential, small thermoelectric potential rate, low sensitive reading, low mechanical strength at high temperature, very sensitive to pollution, expensive precious metal materials, so a large one-time investment.
