The
DT990 is the full-function sensor
designed specifically to meet EPA MACT
requirements. The DT990 is also our
most sensitive model with a minimum
detection limit of 0.01 mg/m3. It
conducts calibration drift and dust
build-up checks automatically and returns
the results to the Quality Assurance
Screen. The DT990 comes with
DustReporter 2 software for regulatory
reporting. The DT990 is the most
cost-effective MACT solution because it
minimizes labor for maintenance and quality
assurance activities.

The
DA550 is an economically priced sensor
that provides trends relative to dust
concentration without the QA features (dust
build-up and calibration checks) of the
DT990. The minimum detection limit is
about 0.1 mg/m3. The DA550 system can
be purchased with a single- or multi-sensor
controller. It can be used for MACT
compliance, but significant operator effort
is required. The features on the
DA550 are comparable to competing DC-based
triboelectric sensors, but the DA550 uses
the patented electrodynamic signal
processing technology.

The
BBS220 is a simple alarm-only sensor
that typically is used to locate baghouse
compartments with leaking filters. It
does not provide a continuous output and
cannot be used for EPA MACT
compliance. The sensitivity of the
BBS220 is adjusted by gathering short-term
data and establishing a reference dust
level. the alarm level is then set as
a multiple of the reference level.
The BBS220 also uses
electrodynamic signal processing and
has a detection limit of about 0.1
mg/m3.

The
SC600 is an optically-based system for
sensing dust concentration in applications
where charged-based systems are not
appropriate such as after an electrostatic
precipitator or in an application with very
sticky or highly conductive
particulate. The SC600 is similar to
an opacity monitor, but it uses
scintillation technology to offset the zero
drift problems associated with opacity
measurements. The minimum detection
limit for the SC600 is about 2 mg/m3.
The control unit contains sensor
diagnostics and data storage. The
SC600 can be used with PCME DustReporter 2
software.

The
PCME-US 100
is a cost-effective dust emission monitoring system for baghouses,
combining low cost, advanced dust detection technology, direct
communication with the PLC and broken bag location by compartment
and/or row. It is designed for use in any process which has particulate
control installed, eg: bag, ceramic and cartridge filters, cyclones and
spray driers, where dust monitoring is required. The system can also
function as an A/D converter fro up to 8 analog inputs.

The
DX800 and DX810
use unique AC Electrodynamic technology. The DC signal created by
particles colliding with a probe inserted in a stack is electronically
filtered out, leaving an AC signal resulting from charged particles
passing and interacting with the rod. Since the signal includes no DC
component, the instrument has minimal cross sensitivity to changing
velocity (application dependent) and has increased stability even with
dust build up on the rod sensor. The dust signal is amplified,
digitised and processed at the probe, consistent with good signal to
noise design techniques. The processed signal is proportional to dust
concentration, although the exact correlation is application dependent.

The
DustSense 30 series is based on
PCME's unique patented TriboACE
technology giving more reliable operation
than Triboelectric dust monitors.
Once installed in the emission stack or
exhaust duct, the average background level
of particulate can be defined. The
alarm levels can then be set to a
percentage or factor above this background
reference level.

|
The
DustSense 10 series of advanced
continuous particulate monitors are based
on PCME's unique patented TriboACE
technology, giving added reliability and
sensitivity over standard Triboelectric
systems. The DustSense 10's alarm
levels can be set as a factor or percentage
of the background level of
particulate. The user has the ability
to set the alarms to instantaneous or
average levels above the background or
normal level of emissions to indicate early
warning of filter failure or gross failure
detection. Alarm delay and data
averaging are user selectable.
