DETECTOR AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a detector, specially one determining the oxygen content in exhaust gases of internal combustion motors, and to a method for the production thereof. The detector comprises a fixture for a sensor element (12) located in a longitudinal bore (16) of a metal casing (10), in which the sensor element (12) is accommodated with a gastight seal. The fixture comprises a ceramic molded part (20) located in the measuring gas portion and a ceramic molded part (27) in the connecting portion, both parts being axially arranged one behind the other. A metal sealing element (52) is hot pressed in a hollow cavity (50) provided between both ceramic molded parts (20, 27).
