Particle Profiler module
The Dust Sentry uses a custom-designed Met One optical particle counter (OPC) to measure four particle size
fractions simultaneously. There is no sharp cut cyclone used in the Particle Profiler; both the concentration
and size are measured inside the optical particle counter.
The three modules for the Particle Profiler are installed in the top right side of the Dust Sentry enclosure.
The Particle Profiler has the sample and purge filters mounted on the outside of the optical module, (in the
Particle Monitor they are held inside).
Figure 12-6 The Particle Profiler uses three modules: a) the optical module on the far right, b) the pump module in
the middle, c) the electronics module on the left
