Beschreibung
Zusammenfassung:	The utility model discloses a multistage particulate matter detection device and system, and the device can comprise at least two groups of probe assemblies, each group of probe assemblies comprises two probes; the probe in the probe assembly is located in the cavity of the bearing part; the two pipeline connecting pieces are respectively connected with the end parts of the bearing piece; the multi-stage particulate matter detection device is used for being connected with a detected pipeline through the pipeline connecting piece so as to detect particulate matter flowing through the detected pipeline through the probe. The device not only can be suitable for particulate matter concentration measurement in multiple measuring ranges, but also can determine other parameters such as particulate matter flow velocity and particulate matter flow through the characteristics of a plurality of probes of the device, and the particulate matter flow velocity and particulate matter flow do not need to be measured through o
