B R S type thermocouple also known as high-temperature precious metal thermocouple, as a temperature measurement sensor, usually used in conjunction with the temperature transmitter, regulator and display instrumentation, etc., to form a process control system for direct measurement or control of a variety of production processes in the range of 0-1700 ℃ fluid, steam and gas media and solid surfaces and other temperatures.
Advantages of B R S type thermocouple
B R S type thermocouple in the thermocouple series has the advantages of high accuracy, good stability, wide temperature range, long service life and high temperature limit. Suitable for oxidative and inert atmosphere, can also be used in vacuum for a short period of time, but not for reducing atmosphere or containing metal or non-metal vapour atmosphere.B-type thermocouple an obvious advantage is that it does not need to be compensated with compensation wire for compensation, because in the range of 0 ~ 50 ℃ thermal potential is less than 3 μV.
Disadvantages f B R S type thermocouple
B R S type thermocouple shortcomings is the thermal potential, thermal potential rate is small, sensitive to read low, high temperature mechanical strength decline, very sensitive to pollution, precious metal materials are expensive, and therefore a larger one-time investment.
