4.4 Smoke and Ash Monitoring
A primary design use for the standard E-BAM is for tracking smoke and ash plumes from wildfires,
prescribed burns, agricultural burns, and even volcanic activity. In these cases, the unit is often
sited at the outskirts of a populated area in the expected path of the smoke plume. The unit is
usually equipped with an optional wind speed and direction sensor for these applications, in order to
correlate changing wind patterns with particulate events. The wind sensor needs to be set up in the
digital link interface (see section 3.5.11) and requires a cross-arm for the tripod mount. See step 5
in section 0 for mounting details.
In smoke tracking applications, the filter tape may be consumed at a much faster rate than normal.
This is because the E-BAM may automatically advance the filter tape to a new spot if the particulate
loading becomes excessive, regardless of the user-defined tape advance setting.
This is based on the measured pressure drop across the filter tape. This feature protects the pump,
preserves accurate flow control, and prevents damage to the filter tape.
