In a device for measuring a fill level of a liquid in a container with an ultrasonic sensor which is arranged on a floor element, wherein a damping cup with a measuring tube is assigned to the ultrasonic sensor, the damping cup has an external housing and an internal housing. The internal housing contains the measuring tube, and either the internal housing has outwardly protruding contact elements that lie against the inside of the external housing or the external housing has outwardly protruding contact elements that lie against the outside of the internal housing. The external housing is also provided and designed for pluggable mounting of of the internal housing, and a channel is formed between the internal housing and the external housing.

A device for determining a filling level of a container is provided, having a damping cup, a measuring section extending vertically inside the damping cup, and having an ultrasound converter arranged at its lower end region, and at least one antechamber. A calming structure is arranged in at least a part of at least one antechamber, to achieve as much degassing of the liquid as possible. The part of the antechamber having the calming structure is designed to be open towards the top over a large area and is connected, via a venting channel, with a vent in the upper region of the device.

In a fluid pressure sensor with a pressure sensing membrane and an electronic circuit, the electronic circuit is in a section realized so thin that a membrane is formed in this section of the electronic circuit. In the other sections, the electronic circuit is realized thicker than in the section that forms the membrane. This makes it possible to manufacture a particularly compact fluid pressure sensor.

A high-temperature sensor comprising a sensor element and a device for holding and positioning the sensor element in a point of use, especially for automotive uses, has a holding part with a pouch molded into it in which the sensor element is received such as to be flush with the surface. In this way, the sensor element is reliably held in a high-temperature sensor and its safe operation is guaranteed also when the sensor is subject to vibrations.

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.

In a method for detecting rain on a windshield, whose degree of wetting is determined with at least one sensor value, it is provided that the sensor value is determined piezoelectrically, wherein vibrations on the windshield are detected, which change depending on the degree of wetting or raindrops hitting the windshield. As a result, the entire windshield serves as a detection surface, thereby yielding a high accuracy.

In a holding device for a sensor, in particular for a rain/light sensor, for mounting on the inner side of a window pane, such as a vehicle pane or suchlike, with at least one holder able to be fastened on the window pane, which holder has a mount for the sensor, and with at least one spring component for fixing the sensor in the mount of the holder, the spring component has detent means for at least a partially detachable connection to the holder. The spring component comprises a spring section with a snap function, which is constructed such that the spring section is in one of two stable spring positions, wherein in one spring position a spring force acts on the sensor.

In the case of a device for ascertaining a fill level of a medium inside a collection container, having at least one measuring chamber, in which an ultrasonic sensor is arranged, connected to conduct media to the collection chamber, and having at least one antechamber connected upstream from the measuring chamber, which has at least one inlet opening for the medium from the collection chamber, at least one flow damper for the medium, according to the invention, is arranged in at least one subarea of the antechamber. Thereby multiple antechambers, which are connected in series one behind another to conduct media, are connected upstream from the measuring chamber.

The invention relates to a sensor arrangement for detecting ambient conditions, in particular for a motor vehicle, with at least one carrier plate and optical elements arranged on this carrier plate, wherein several of the optical elements are arranged around a shared central region on the carrier plate, and at least two of the optical elements arranged around the central region exhibit primary action axes. These primary action axes are adjusted at a predetermined angle relative to the carrier plate, wherein the primary action axes are directed toward the shared central region. Additional sensors arranged on the carrier plate include a rain sensor, a solar sensor as well as various light sensors, which preferably are arranged on receiving surfaces of the carrier plate.
