摘要： An oxygen sensor is provided with a virtual point contact electrode to improve performance, extend operational life and to minimize thermal shock breakage; it is also provided with reduced annular space between the protective sheath and zirconia electrolyte, and minimized communicating openings to the furnace atmosphere, in order to reduce burnoff air flow during probe conditioning.
