Abstract

Die Erfindung bezieht sich auf eine Druckmesseinrichtung (24) für eine Aufladeeinrichtung (10), die insbesondere als Abgasturbolader beschaffen ist. Die Druckmesseinrichtung (24) dient zur Erfassung eines Druckes p2 eines gasförmigen Mediums (18) in einem Volumen (22). Das Volumen (22) befindet sich vorzugsweise innerhalb des Verdichtergehäuses (14) des Verdichterteils (12). Die Druckmesseinrichtung (24) weist ein zurückversetzt angeordnetes Sensorelement (34) auf, welches in einem Abstand (44) von einer das Volumen (22) begrenzenden Wand (16) angeordnet ist.

The invention relates to a pressure measuring device (24) for a charging device (10), which is designed in particular as an exhaust gas turbocharger. The pressure measuring device (24) serves to detect a pressure p 2 of a gaseous medium (18) in a volume (22). The volume (22) is preferably located inside the compressor housing (14) of the compressor part (12). The pressure measuring device (24) has a recessed sensor element (34) which is arranged at a distance (44) from a wall (16) delimiting the volume (22).
