Abstract
The invention relates to a mass tube (1) for an air measuring sensor (3) comprising a metal grid (4) acting as a flow rectifier arranged perpendicular to the air flow (2). At least two fixing elements (5) are arranged on the measuring tube (1), said elements extending inwards in a radial manner, whereon the metal grid (4) is fixed by pre-tensioning.
Claims6
A measuring tube for an air mass sensor, comprising a metal grid arranged therein transversely to an air flow and functioning as a flow straightener, wherein the measuring tube has arranged on it at least two fastening elements which extend radially inward and to which the metal grid is fastened under prestress.
A method for producing a measuring tube for an air mass sensor, comprising:
- a metal grid arranged therein transversely to an air flow and functioning as a flow straightener, wherein the measuring tube has arranged on it at least two fastening elements which extend radially inward and to which the metal grid is fastened under prestress,
- the fastening elements are bent in or opposite to the air flow direction by means of a tool,
- the metal grid is fastened to the fastening elements, and the tool is removed.
