Summary of B type thermocouple

Summary of B type thermocouple overview of English name: B type thermocouple nickel chromium silicon - Nickel silicon thermocouple ( B type thermocouple) For inexpensive metal thermocouple, thermocouple is a new international standard of *, is successfully developed by the Australian defence laboratory, in the early 70 s it overcome the K type thermocouple two important faults: K type thermocouple between 300 ~ 500 ℃ due to the lattice short-range order of nickel-chromium alloy thermoelectric emfs caused by unstable; At about 800 ℃ caused by nickel chrome preferential oxidation thermoelectric emfs instability. The anode ( NP) Chemical composition as follows: in the name of the Ni, Cr, Si = 84. 4:14. 2-1. 4, the cathode ( NN) In the name of the chemical composition is: Ni: Si, Mg = 95. Five. 4-0. For - 1, its working temperature 200~1300℃。 N type thermocouple has advantages of good linearity, thermoelectric emfs, high sensitivity, good stability and uniformity, oxidation resistance is strong, cheap, is not affected by short-range ordering etc, and its comprehensive performance is better than that of K type thermocouple, is a kind of very promising thermocouple type B thermocouple cannot directly at high temperature for sulfur, reducing or reduction, oxidation atmosphere and vacuum alternately, is not recommended for people with weak oxidizing atmosphere.
