Abstract
The invention relates to a device having a sensor carrier, which comprises a sheet-metal element and a plastic element and on which a measuring element introduced into the flowing medium is disposed. The use of plastic, which for the most part covers the sheet-metal element, means closer tolerances, which improve the performance of the sensor carrier both in terms of its facing into the flow and experiencing a flow around it, for instance by providing it with an improved aerodynamic leading edge, or the measuring element can be mounted flush to the surface and flush with edges of a sensor cavern, so that no turbulence occurs in the medium in the region of the measuring element or flow under the measuring element. The sensor region of the measuring element is reliably protected by recesses in the longitudinal edges and by a special adhesive bonding process from a gel emerging from the electronic evaluation circuit, so that the measuring characteristic curve behavior is not altered.
