摘要： The invention is directed to a flow sensor having a heater, two temperature measuring sensors, a heater temperature sensor and a medium temperature sensor. A control circuit is provided which controls the overtemperature of the heater in dependence upon the temperature of the flowing medium. With this arrangement, the influence of the temperature dependency of the following on the sensor characteristic are compensated: viscosity, thermal conductance and thermal capacity of the medium. The relationship between the heater temperature and the temperature of the medium is adjusted in a slightly nonlinear manner by means of special evaluation circuits. In this way, a further improvement of the temperature compensation is obtained.

At least one heater is arranged on the membrane. The measurement chip is installed in the in-flow channel of a housing. By means of the structure of the housing, contamination of the measurement chip is reduced, thermal equalization with the media flow is improved, the resistance of the sensor to sudden pressure variations is increased, and the dielectric contacts are improved.

摘要： An apparatus for determining the flow rate of a flowing medium having a substrate as a carrier and a resistor arrangement disposed on the substrate which among other elements includes a layer-like measuring resistor (R.sub.H) as well as a likewise layer-like heating resistor (R.sub.S), the heating output of which is regulated such that the measuring resistor (R.sub.H) has a constant temperature, the heating output of the heating resistor (R.sub.S) being a standard for the flow rate of the flowing medium. The surface area of (R.sub.S) is greater than the surface area of (R.sub.H) and extends farther toward a fastening of the substrate, in order to prevent a flow of heat out of the vicinity of the measuring resistor (R.sub.H). The measuring resistor (R.sub.H) and the heating resistor (R.sub.S) are located on the downstream portion of the substrate, on a lip set off by a slit. With this disposition of the measuring resistor (R.sub.H), soiling of the substrate affects the measurement result only slightly.

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.

摘要： A device for measuring the mass of a flowing medium, or flow rate meters, having a measuring element accommodated in a measurement support; upstream of the measuring element, a grid with flow openings is provided. To attain a substantially rotational symmetrical velocity distribution even in the case of a severely impeded oncoming flow, the grid has flow openings, which at least regionally have a different flow cross section. The flow cross sections of the flow openings are adapted to the oncoming flow, in order to bring about a flow with substantially even velocity distribution downstream of the grid. The device is intended for measuring the mass of a flowing medium, in particular for measuring the mass of aspirated air in internal combustion engines.

摘要： A measuring element for determining the flow rate of the aspirated air of an internal combustion engine comprising a substrate, which is divided by two parallel separating slits of equal length into three prongs on which temperature-dependent resistor tracks are disposed. The measuring element has separating slits of optimized shape. To lessen the notch action and reduce tension peaks at the ends of the slits, one separating slit has a segment with a curved course, and another separating slit has a slit end embodied as an enlargement. The novel measuring element is especially suitable for determining the flow rate of the aspirated air in internal combustion engines.
