| Zusammenfassung: | A particle sensor device (1) has an optical unit (5), by means of which the particle load of a measured gas volume can be detected; a measuring chamber (2) in which the optical unit (5) is arranged and into which a measured gas can be introduced through an inlet channel (3); and a primary air duct (6) through which the measured gas can be discharged from the measuring chamber (2) by means of a fan(7). To provide an optimal flow condition for the measurement process through the optical unit (5) inside the measuring chamber (2) as much as possible, it is proposed that the particle sensor device(1) has a secondary air channel (9) that is connected to a primary air channel (6) position on the primary air channel (6) which is arranged downstream of the measuring chamber (2) and which has pressure higher than the pressure in the measuring chamber (2), and connected to the measuring chamber (2) or to an area of the inlet channel (3) arranged upstream of the measuring chamber (2).
