Abstract
(DE)
Partikelsensor mit einer Partikelaufladeeinrichtung zum Aufladen von Partikeln in einem Fluidstrom, und einer Sensoreinrichtung zur Erfassung eines zeitlichen Verlaufs eines Sensorsignals, das Informationen über aufgeladene Partikel in dem Fluidstrom aufweist, wobei der Partikelsensor dazu ausgebildet ist, ein Auswertungszeitfenster in Abhängigkeit wenigstens einer eine Geschwindigkeit des Fluidstroms charakterisierenden ersten Größe zu ermitteln und den zeitlichen Verlauf des Sensorsignals wenigstens in einem durch das Auswertungszeitfenster charakterisierten Zeitbereich auszuwerten.
