Abstract: A particle sensor for determining the concentration of soot in the exhaust gas of an internal combustion engine. The particle sensor includes a sleeve-shaped sensor housing, a sensor element fixed in the sensor housing and projecting beyond the sensor housing on the exhaust gas side, and a sleeve-shaped protection tube fastened to the sensor housing on the exhaust gas side, the protection tube including an inner protection sleeve and an outer protection sleeve, the inner protection sleeve surrounding an exhaust-gas-side end region of the sensor element, the outer protection sleeve surrounding the inner protection sleeve at least in some regions, so that an annular space is formed between the outer protection sleeve and inner protection sleeve. The outer protection sleeve and the inner protection sleeve each have a gas outlet and a gas inlet.

Abstract: 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.

Abstract: 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.

Abstract: A gas sensor for determining at least one constituent or at least one property of a measuring gas, in particular, of an exhaust gas of an internal combustion engine, including a sensor element. An outer protective tube of the gas sensor includes at least one inlet opening for measuring gas to enter into an outer chamber, the at least one inlet opening includes at least one swirl element for forming a vortex about the longitudinal direction in the outer chamber. The outer chamber protrudes distally beyond a housing in the longitudinal direction by an outer chamber longitudinal extent and an inner chamber protrudes distally beyond the housing in the longitudinal direction by an inner chamber longitudinal extent, and the outer chamber longitudinal extent being at least twice as large as the inner chamber longitudinal extent.

Abstract: 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.

Abstract: 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°. The sensor device is highly resistant to thermal shock, while, at the same time, the sensor element has a high dynamic response.
