Mounting arrangement of a metal film resistor of an anemometric measuring device within an exhaust gas conduit

The arrangement has a film resistor (2) that is mounted in a support (3) i.e. hollow body. The support is sealed against a shield (4a) or a housing (4b) that is tightly connected to an exhaust pipe or an exhaust gas recirculation pipe. The support and the shield or the housing are sealed at a distan...

Beschreibung
Zusammenfassung:	The arrangement has a film resistor (2) that is mounted in a support (3) i.e. hollow body. The support is sealed against a shield (4a) or a housing (4b) that is tightly connected to an exhaust pipe or an exhaust gas recirculation pipe. The support and the shield or the housing are sealed at a distance against each other radially outside the exhaust pipe or the recirculation pipe. The film resistor is protruded in the exhaust pipe or the recirculation pipe. Electrical lines for the resistor are arranged in a longitudinal direction of the support. Independent claims are also included for the following: (1) a method for manufacturing a measuring device (2) a method for self cleaning of a hot film anemometer (3) a method for manufacturing a hot film anemometer. Die Erfindung betrifft die Anordnung eines Schichtwiderstands (Chip) in einem Abgasrohr oder Abgasrückführrohr, wobei der Schichtwiderstand in einem Träger befestigt ist, der gegen eine Abschirmung oder ein Gehäuse abgedichtet ist, die oder das dicht mit dem Abgasrohr oder Abgasrückführrohr verbunden ist, wobei der Träger und die Abschirmung oder das Gehäuse radial außerhalb des Abgasrohrs oder Abgasrückführrohrs von diesem beabstandet gegeneinander abgedichtet sind.
