摘要： In a gas sensor comprising a housing, a membrane and a sensor element, wherein the housing comprises a measuring chamber and an air supply opening, the sensor element is disposed in the measuring chamber and the membrane separates the measuring chamber from the air supply opening, a particularly good air exchange should be achieved. This is accomplished by providing a flow guiding device in the air supply opening of the housing. The flow guiding device here projects into the housing.

摘要： A device for detecting a structure-borne sound signal, in particular for detecting a structure-borne sound signal caused by an event of damage on a component to be monitored, having at least one structure-borne sound sensor, at least one signal-conducting connection of the structure-borne sound sensor to an evaluation device, and a protective body. The structure-borne sound sensor has a structure-borne sound-conducting connection to the protective body and the protective body has a structure-borne sound-conducting connection to the component to be monitored.
