Abstract
An optical particle sensor device comprises an optical emitter device for emitting a multitude of measurement laser beams; a detector device for detecting the measurement laser beams scattered on particles in the vicinity of the optical particle sensor device and for generating a single measuring signal assigned to this for each measurement laser beam; and an evaluation device for determining at least one estimated particle value for the number of particles per volume using at least one single measurement signal, wherein the evaluation device determines at least two estimated particle values for the number of particles per volume, which are based on at least partially different single measurement signals and/or a different number of single measurement signals, and on the basis of at least part of the estimated particle values, determines at least one output value for the particle load.
