摘要： An electrochemical measuring sensor for determining the oxygen content of gases, such as exhaust gases of internal combustion engines, includes a housing having an annular sealing seat defined on an inner surface thereof; a sensor element which is comprised of a solid electrolyte body which is oxygen-ion conducting, which has a form of a tube having a closed end and which has an annular shoulder provided thereon; and a seal ring positioned between the annular sealing seat of the housing and the annular shoulder of the solid electrolyte body, and including a plurality of resilient elements distributed thereon. Each of the plurality of resilient elements has a lower portion and an upper portion angled toward the housing, and the seal ring has a clear width so that each lower portion rests on and is mechanically prestressed against the annular shoulder of the sensor element and each upper portion is mechanically prestressed against the housing, whereby a tight seal of the sensor element to the housing is provided and the sensor element is maintained within the housing under mechanical prestress and secure against relative rotation.
