to measure the mass of exhaust parti culates. It can be used either for in-use
applicati ons or in test cells, while meeti ng requirements of US EPA 1065.
The system consists of a cyclonic separator to remove coarse parti cles,
three traditi onal 47 mm fi lter holders, a mass fl ow controller to adjust
fi lter face velocity, a high capacity vacuum pump, pneumati c ball valves
to engage fi lters, downstream isolati on solenoids, and an opti onal heated
sample line. All wett ed surfaces are stainless-steel, heated to 47°C. The
system can be operated from the built-in interface panel, or opti onally
through the SEMTECH-DS host soft ware where sampling can be automated
based on NTE signals, engine RPM, exhaust fl ow rate, or other user-defi ned
parameters.
