Abstract
A measuring element for a device for determining the mass of a flowing medium. The measuring element has a plurality of resistor tracks exposed to the flowing medium, and a substrate carrying the resistor tracks, on the surface of which substrate the resistor tracks are disposed, separated from one another. To prevent alteration of the characteristic curve of the measuring element as a consequence of the provision of temperature decoupling slits in the substrate, transversely to the flow direction, the resistor tracks are disposed in succession, as viewed in the flow direction, in stairstep fashion with steps that protrude past the respective preceding resistor track. The substrate is notched in accordance with the stairstep shape of the resistor tracks, in such a manner that one leading edge is formed along each step of the resistor tracks, so that the oncoming flow to the various resistor tracks is unaffected by the preceding step.
