Analysis device of the oxygen content of the atmosphere of a furnace, in particular heat treatment of the steels.

摘要

This device is of the type comprising a probe having a first tube closed at one of its ends, made from a material forming an electrolyte, such as zirconia, and containing, on the one hand, a reference air intake piping, and, on the other hand, a reference electrode and a second tube which, made for example from ceramics, closed at one of its ends and containing the first tube and the measurement electrode, delimits the analysis chamber in communication with the enclosure whose oxygen content is to be measured. According to the invention, it comprises means 30 for periodic injection of CO2 inside the analysis chamber. IMAGE
