B type thermocouple/platinum rhodium thermocouple

Specifications

Thermocouple

Platinum and rhodium 30 - platinum-rhodium 6 thermocouple (b-type thermocouple) as precious metal thermocouples. Provisions of thermocouple wire diameter 0.5mm, tolerance-0.015mm, the positive electrode (BP) of the nominal chemical composition of platinum-rhodium alloy containing 30% rhodium, 70% platinum, a negative electrode (BN) as a platinum-rhodium alloy, rhodium is 6%, it is commonly known double platinum and rhodium thermocouple. The long-term maximum use temperature of the thermocouple 1600 °C, short-term maximum use temperature of 1800 °C. b-type thermocouple thermocouple series with the highest accuracy, the best stability, wide temperature zone temperature, long life, temperature maximum advantages. Suitable oxidizing and inert atmosphere, a vacuum can also be used in the short term, but is not applicable to a reducing atmosphere or an atmosphere containing vapor of metal or nonmetal. B-type thermocouple An obvious advantage of not compensating cables compensation, because in the range of 0 ~ 50 °C thermopower less than 3μV. b-type thermocouple thermoelectric power is inadequate, thermoelectric power is small, low sensitivity, high temperature mechanical strength, very sensitive to contamination, expensive precious metals, and thus a one-time investment is large.

b-type thermocouple models and specifications:

b-type thermocouple is actually dividing number B double platinum and rhodium thermocouple, which can measure 0 ~ 1800 °C temperature of the medium, in 1300 ~ 1600 °C for long-term use. Thermocouple temperature measurement is the best. The main technical parameters Product performance standards IEC584 IEC751 JB/T5582-1991

Ordering:

1 indicate the thermocouple type, index number, temperature.
