摘要： A hot-film air-mass meter for measuring an air-mass flow which flows in the main direction of the flow, which can be used, in particular, in the intake tract of an internal combustion engine. The hot-film air-mass meter comprises a sensor chip having a measuring surface. The air-mass flow flows essentially parallel over one surface of the sensor chip. A flow separating element is mounted upstream from the measuring surface with respect to the main flow direction. The at least one flow separating element is designed in such a way that the air-mass flow is separated from the measuring surface of the sensor chip in at least one separation zone prior to reaching the measuring surface.

摘要： An ultrasonic flow rate meter and a method for measuring the flow rate with the aid of ultrasound are described, having at least two ultrasonic transducers situated offset in a flow channel in the flow direction for transmitting and receiving ultrasound wave packets, so that ultrasound propagation times from one of the ultrasonic transducers to the other, and vice-versa, can be determined in an electronic part, and having a pressure sensor associated with the flow channel for determining the pressure in the flow channel. Measured values for an engine control that is as accurate as possible are determinable by accurately detecting the incoming air in the intake of a motor vehicle internal combustion engine.

摘要： A micromechanical sensor and a method for manufacturing a micromechanical sensor which has at least one membrane are provided. The membrane is made of a first material which is accommodated in a surrounding second material, and the membrane is configured for sensing a medium surrounding it. The membrane is reinforced, at least partly, by a third material at break-sensitive points on the membrane rim. Reinforcement of the membrane rim increases the stability and thus also the service life of the membrane and the sensor.

摘要： A method for cleaning of a measuring element (1) passed over by a gas flow is arranged on a thin-walled membranous material (5). The measuring element (1) includes at least one heatable element (6, 7, 8; 10, 11), which is arranged on the membranous material, the membranous material being capable of vibrating. By means of a control apparatus (20) or a switching (22) associated with the measuring element, a periodic delivery of current (41, 42) in intervals takes place in this manner to at least one heatable element (6, 7, 8; 10, 11) of the measuring element (1) and thereby produces vibrations. Alternatively, vibrations of the membranous material (5) can be produced by special vibration exciters or by means of ultrasonic coupling.

摘要： A gas flow determination method and a corresponding gas flow determination device. A sensor device including a diaphragm and a frame enclosing it is provided; a predetermined temperature profile is created on the diaphragm; the gas flow to be determined is directed over the diaphragm in a predetermined direction of flow; the change in the temperature profile caused by the gas flow is detected; and the gas flow is determined on the basis of the change thus detected. The temperature at a third location on the diaphragm upstream from the first location and optionally at a fourth location downstream from the second location is regulated at a value corresponding to the local value of the predetermined temperature profile. In this manner, the effect of soiling on the diaphragm may be minimized effectively.

摘要： A device for measuring the mass of a flowing medium by use of a temperature-dependent measuring resistor bathed by the flowing medium and accommodated in a measuring channel. The device has a flow obstacle, embodied in the form of a trip edge, upstream of the measuring element in the region of an inlet opening of the measuring channel, so as to create a chronologically and spatially stable separation zone in the region of the trip edge, thereby preventing chronologically and spatially unstable separation zones and makes it possible to attain a reduction in measuring signal noise. The invention is contemplated for measuring the mass of a flowing medium, especially for measuring the aspirated air mass in internal combustion engines.
