    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 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.

    摘要: A device for measuring at least one parameter of a medium flowing in a line, particularly the intake-air volume of an internal combustion engine. Liquid particles contained in the line act upon a measuring element and influence a characteristic curve of the measuring element which is used to determine parameters of the flowing medium. The characteristic curve of the measuring element can be changed disadvantageously by solid-matter particles. In order to reduce the action of solid-matter particles on the measuring element, a protective grating is proposed in which side walls of channels of the protective grating form various angles of intersection with the flow direction. Solid-matter particles are thereby diverted into a path of motion around the measuring element.

    摘要: A device for measuring the mass of a flowing medium having a temperature-dependent sensor element, which is inserted flush in a recess of a sensor carrier and is retained therein by means of an adhesive. The sensor carrier is made by bending a thin metal strip and has two elements, a frame element and a retaining element, which together form a recess, into which the sensor element is inserted flush and glued by means of an adhesive to a plateau-like protuberance of a bottom face of the retaining element. The sensor carrier is intended for a device for measuring the mass of a flowing medium for measuring the flow rate or mass of the air aspirated by internal combustion engines.

    摘要: A device for measuring the mass or flow rate of a flowing medium of the air aspirated by an internal combustion engine including an electronic control circuit, which evaluates the electrical signals of a temperature-dependent sensor element and which is accommodated together with the sensor element in a metal protective housing, for the sake of protecting the sensor element against entering electromagnetic waves (EMC protection). To reduce the expense and structure space, the device has a protective housing, which is composed in plug-together fashion of a metal bottom housing, a metal closure housing, and a metal plug part. The plug part has a plurality of leadthrough capacitors for noise suppression of the electrical connection line passed through the plug part and connected to the electronic control circuit.

    摘要: A rotary position transducer for generating electrical rotary angle signals as a function of the pivoted position of a rotary device, in particular a throttle valve in the fuel supply system of an internal combustion engine, has a first carrier with concentrically disposed electric contact tracks and a second carrier with fixedly disposed wipers, which rest with axial pressure on the contact tracks. One of the two carriers is rotatable relative to the other, and the rotatable carrier has a securing element for coupling of the rotary device in a manner fixed against relative rotation. To suppress a transmission of radial and axial play of the rotary device to the arrangement of wipers and contact tracks, the securing element is joined to the carrier via a spring coupling that is torsionally rigid in the rotational direction but highly elastic in the axial and radial direction.

    摘要: Known devices for measuring the mass of a flowing medium, or flow rate meters, have a measurement element accommodated in a measurement stub, and a flow rectifier with a grid is provided upstream of the measurement element. For easy production and assembly and accurate alignment of a grid (21) with a flow rectifier (20) of the device (1), the grid (21) has integrally formed-on spring elements (30), which deform elastically when the flow rectifier (20) is installed so that by their spring force, in combination with a detent connection (33, 35) provided on the flow rectifier (20), they durably retain the flow rectifier (20) and the grid (21). The device is intended for measuring the mass of a flowing medium, especially for measuring the flow rate of air aspirated by internal combustion engines.
