Abstract (en)

[origin: EP1306462A2] Measurement and/or regulation of the carburization atmosphere in a carburization chamber (3) of a vacuum gas carburization system (1) comprises introducing workpieces into the chamber, providing and maintaining a vacuum in the chamber, introducing a carburization gas into the chamber and measuring the atmosphere in the chamber using a probe. <??>An Independent claim is also included for a vacuum gas carburization system comprising at least one carburization chamber having an opening in which a probe for measuring the atmosphere in the chamber is arranged in a vacuum-tight manner. <??>Preferred Features: The probe is a vacuum-tight oxygen sensor used for measuring zirconium oxide ceramic.
