An exhaust gas sensor for detecting a measurement gas component, having a ceramic sensor element fixed in a housing, and a double-walled protective pipe having outer and inner protective sleeves, the inner sleeve enclosing a gas chamber into which the sensor element extends with a segment at the measurement gas side, in the direction of a longitudinal axis of the sensor, and an annular chamber being formed between the outer and inner protective sleeves. The outer sleeve has a cladding surface having at least one opening configured as a swirling element, through which measurement gas can move into the annular chamber with rotation about a longitudinal axis of the sensor, and the inner sleeve has at least one opening that is adjusted and/or functionally optimized, as to a sensitive region of the sensor element, through which opening the measurement gas can move from the annular chamber into the gas chamber.

Exhaust gas sensor

A sensor for detecting particles, in particular, soot particles, is described. The sensor includes a sensor element having at least two measuring electrodes, which are situated on a carrier substrate, and a protective tube assembly having at least one outer protective tube and one inner protective tube. The sensor element is situated in the inner protective tube in a longitudinal extension direction. The outer protective tube and the inner protective tube are designed to permit the particles to access the sensor element in a direction deviating from the longitudinal extension direction.

Sensor for detecting particles

Gas sensors are provided that are fashioned such that there is an increased flow over the sensor element. In this way, a good measurement dynamic is achieved even when these gas sensors are exposed to exhaust gases having a low flow speed.

Gas sensor

A sensor device for measuring at least one property of a fluid medium, in particular of an exhaust gas of an internal combustion engine. The sensor device includes at least one protective housing for accommodating at least one sensor element; within the protective housing, at least one flow path being provided that allows flow therethrough by the fluid medium. The flow path has a number of at least three deflection points, where the fluid medium undergoes a directional change about an angle of at least 90&#xb0;. The sensor device is highly resistant to thermal shock, while, at the same time, the sensor element has a high dynamic response.

Sensor device for measuring at least one property of a fluid medium

A turbocharger for use in an internal combustion engine has at least one turbocharger housing, at least one compressor situated inside the turbocharger housing, and at least one turbine situated inside the turbocharger housing. In addition, the turbocharger has at least one sensor device for detecting at least a portion of a gas component of an exhaust gas of the internal combustion engine. The sensor device is at least partially integrated into the turbocharger housing.
