ABSTRACT:
A protective cap is provided for a sensor having a sensor element, which is disposed in a housing and includes a connection side and a measuring side, for determining gases in gas mixtures. The protective cap delimits a sensor element chamber having at least one flow outlet and an antechamber that has at least one flow inlet and is in fluid connection with the sensor element chamber in order to protect the sensor element on the measuring side. A condensate separator is provided in the antechamber. A device for deviating the flow is provided between the sensor element chamber and the antechamber and a device for accelerating the flow is provided on a flow outlet side of the sensor element chamber. A gas sensor is equipped with the protective cap.
