    摘要： To determine air mass flows, especially for controlling internal combustion engines, a hot-film air-mass sensor is provided, which may be used especially for sensing air mass flows in the intake tract of an internal combustion engine. The hot-film air-mass sensor has a sensor chip having a sensor frame and a sensor diaphragm having at least one heating element and at least two temperature sensors. Furthermore, the hot-film air-mass sensor has a chip carrier for mounting the sensor chip, as well as at least one additional heating element. The sensor chip is able to be heated up using the at least one additional heating element, which is inserted into the chip carrier. Compared to the usual devices, the hot-film air-mass sensor has a lower susceptibility to contamination, especially by oil films.

    摘要： An ultrasonic flow sensor for measuring the volumetric flow rate of a flowing medium through a flow channel having a transducer array which is situated within the flow cross section of the flow channel and which generates ultrasonic waves which propagate in the flow cross section of the flow channel transversally to a flow direction of the flowing medium, the ultrasonic transducer array having an interlaid arrangement of transducer elements which act alternately as transmitting and receiving antennas, so that all emitted individual sound waves interfere to form common wave fronts.

    摘要： A flow sensor is described, in particular for analysis of gas flows, having a substrate and at least one sensor component which is sensitive to a flow of a medium, the sensor component being separated from the substrate in at least some areas by a region that is a poor heat conductor compared to the substrate. In addition, the region having poor heat conductivity is a porous silicon region or a porous silicon oxide region, or the region having poor heat conductivity is a recess in the surface of the substrate above which the sensor element (15) is situated on at least one web which bridges the recess and is at least mostly unsupported. The flow sensor described here is particularly suitable for angle-dependent detection of a gas flow.
