Abstract
An air mass flowmeter with a housing having an air-guiding path in which an air mass sensor element is arranged on a sensor element carrier in the housing and is electrically connected to a circuit carrier by connection wires. The circuit carrier is also arranged in the housing the air mass sensor element is positioned accurately in the air-guiding path by a positioning element that engages into a positioning element receptacle formed in the sensor element carrier.
Claims21
An air mass flowmeter comprising:
- an air mass sensor element;
- a housing having:
- an air-guiding path in which the air mass sensor element is arranged;
- and
- a tapered positioning element formed on the housing;
- a sensor element carrier arranged in the housing and on which the air mass sensor element is arranged;
- a circuit carrier arranged in the housing to which the an air mass sensor element is electrically connected to via connection wires;
- and
- a positioning element receptacle formed in the sensor element carrier and configured to directly engage with the tapered positioning element formed on the housing as a result of which the air mass sensor element is precisely positioned in the air-guiding path, wherein the positioning element receptacle is spaced inboard from an edge of the sensor element carrier.
