Special seal geometry for exhaust gas sensors for producing high leak tightness with respect to the measurement chamber

The invention relates to a sensor system (110) for detecting at least one property of a measured gas in a measured-gas chamber (112). The sensor system (110) comprises a probe (114) for detecting the property of the measured gas. The probe (114) comprises at least one sensor element (116) and at least one housing (118) surrounding the sensor element (116). The housing (118) is designed in such a way that the measured gas can be fed to the sensor element (116) in the housing (118). The sensor system (110) further comprises an accommodating element (126) that can be connected to a wall (128) of the measured-gas chamber (112). The probe (114) can be inserted into the accommodating element (126) along an insertion axis (130) and can be fixed in the accommodating element (126). The probe (114) can be sealed off from the measured-gas chamber (112) by at least one seal (140). The seal (140) comprises at least one linear seal.
