Mixing device for particulate matter

Especially interesting for

the measurement of particulate matter and particles

exhaust gas measuring techniques

The mixing device (red) surrounds a central flow channel and feeds a diluting gas into the channel to optimize the mixing process.

To date, two types of particulate matter or of fluid media (as encountered in exhaust gas measuring techniques) have been mixed by feeding one of the media laterally to the flowing direction of the other medium. These two media only mix homogeneously far way from the feeding point. A mixing module developed at PTB reduces the length of the section required for this process to take place, which can save costs in terms of material and space. Furthermore, this device enables a thorough mixing of two flows without the formation of interfaces. (Technology Offer 0472)
