product description:
The positive electrode (BP) is a platinum-rhodium alloy, which contains 30% rhodium and 70% platinum. The positive electrode is platinum-rhodium 30.
The negative electrode (BN) is a platinum-rhodium alloy with a rhodium content of 6%. The negative electrode is platinum-rhodium 6.
Use environment:
1: Suitable for oxidizing and inert atmospheres, and also for short-term use in vacuum.
2: Not suitable for reducing atmosphere or atmosphere containing metal or non-metal vapor.
Advantages of B-type thermocouple:
1: Type B thermocouple does not need to use thermocouple compensation wire, because the thermoelectric potential is less than 3μV in the range of 0~50℃.
2: Has the highest accuracy in the thermocouple series
3: It has the best stability in the thermocouple series,
4: The measuring temperature range is very wide,
5: Long service life
6: The upper limit of the measurement temperature is relatively high
Disadvantages of type B thermocouple
1: The thermoelectric potential rate is small,
2: Low sensitivity,
3: The mechanical strength decreases under high temperature,
4: Very sensitive to pollution,
5: Precious metal materials are expensive,
Measuring temperature range of type B thermocouple
1: Type B thermocouple can measure the temperature of the medium from 0 to 1800°C.
2: Type B thermocouple can be used for a long time at 1300~1600℃.
3: Type B thermocouple is the best thermocouple for high-temperature measurement.
