  • Particulate matter sensor device
    Patent number: 11898953
    Abstract: A particulate matter sensor device comprises an enclosure (21) defining a flow channel (2), a radiation source (3) for emitting radiation into the flow channel for interaction of the radiation with particulate matter in an aerosol sample in the flow channel, and a radiation detector (4) for detecting at least part of said radiation after interaction with the particulate matter. The sensor device comprises a flow modifying device (511) arranged upstream of the radiation detector and/or radiation source so as to reduce particulate matter precipitation onto the radiation detector, the radiation source and/or the channel wall sections in their proximity. The invention also relates to a method of determining parameters of particulate matter in an aerosol sample by using such a particulate matter sensor device.
