Patent number: 11965807Abstract: A duct probe (20) for sampling a fluid from a main fluid flow (Fm) in a duct (10) defines an elongated supply channel (21) n elongated discharge channel (22). The supply channel has at least one inflow opening (23) for diverting a partial flow (Fp) from the main fluid flow into the supply channel, and the discharge channel has at least one outflow opening for returning the partial flow from the discharge channel into the main fluid flow after it has passed an environmental sensor (30). The duct probe further comprises at least one compensation opening (26) that connects the supply channel and the discharge channel in a region that is located between their closed and open ends. By the presence of the compensation opening (26), a jet flow (Fj) is created, which acts to reduce a pressure difference between the supply channel and the discharge channel when the duct probe is exposed to the main fluid flow (Fm).Type: GrantFiled: May 19, 2020Date of Patent: April 23, 2024Assignee: Sensirion AGInventors: Nicolas Moeller, Mark Hornung, Stefan Thiele, Patrick Leidenberger, Stefan Kostner

Patent number: 11940370Abstract: A particulate matter sensor device comprising an enclosure (21) that comprises a flow inlet (11), a flow outlet (12) and a flow channel (2) extending therebetween, a radiation source for emitting radiation into the flow channel (2) for interaction of the radiation with the particulate matter in the flow (20) of an aerosol sample when guided through the flow channel (2), 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 (4) and/or of the radiation source (3) for modifying the flow (20) for reducing particulate matter precipitation onto the radiation detector (4) and/or onto the radiation source (3) and/or the channel wall sections in close proximity to the detector (4) and/or source (3). 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.Type: GrantFiled: September 17, 2021Date of Patent: March 26, 2024Assignee: Sensirion AGInventors: Frank Gütle, Ulrich Leidenberger, {hacek over (Z)}eljko Mrcarica, Stefan Kostner, Stefan Thiele
