Abstract (en)
[origin: DE4435885A1] The invention relates to an electrochemical measuring sensor to determine the oxygen content of gases, and especially that of the exhaust gases of internal combustion engines, with a sensing element sealed into a metal casing, in which there is at least one seal between the sensing element and the casing. The seal (30) consists of a finely ground or powdered material, the volume of which in the uncompressed state is greater than that of a sealing gap (74) between the sensor (22) and the casing (12), whereby the seal is inserted in its large volume between sealing regions of the sensor (22) and the casing (12) and is compacted when the sensor (22) and the casing (12) are assembled together.
