PCME provide a complimentary range of particulate
monitoring technologies to ensure that only the right technique is used
in a particular application. Interference and cross-sensitivities are
minimised by selection of the most appropriate technology.
ElectroDynamic™
Probe Electrification Particulate Emission Monitoring
|
|
Principle of Operation
- Technique based on a charge
induction principle derived from particle interaction with
probe. Instrument output is an analysis of this frequency
response.
|
|
Applicability
|
Dust Concentration
|
Certification
|
|
Bagfilters, Cyclones, Humid air streams
|
0.01 mg/m3 to
10,000 mg/m3
|
0-15 mg/m3
(MCERTS/TUV)
|
Unique
Features
- Unaffected by contamination of probe
- Unique solution for dryers and
humid gas streams
- Optimised to tolerate change in
velocity of 8-18 m/s
|
- Zero and span checks
- Patented insulated sensor for humid
applications
- Patented probe contamination check
|
Pro-scatter™
Forward Scatter Particulate Emission Monitoring
|
|
Principle of Operation
- Cone of scattered light from
particles within the measurement volume of the sensor probe is
collected and measured
|
|
Applicability
|
Dust Concentration
|
Certification
|
|
Incinerators with dry scrubbers,
cement kilns, power plant (oil, gas and coal fired)
|
0.1 mg/m3 to
1,000 mg/m3
|
0-15 mg/m3
(QAL1)
|
Unique
Features
- Cone measurement increases particle
interaction volume
- Extended temperature range (no
fibre optics)
|
- Detector position unchanged in
self-check mode
- Self-checks to meet PS-11 and QAL3
(EN-14181)
|
DynamicOpacity™
Ratiometric Opacity
Particulate Emission Monitoring
|
|
Principle of Operation
- Ratiometric measurement based on
light variation
|
|
Applicability
|
Dust Concentration
|
Certification
|
|
Bagfilters, Electrostatic
Precipitators, Cyclones, Boiler Stacks
|
10 mg/m3 to
20,000 mg/m3
|
0-150 mg/m3
(MCERTS/TUV)
|
Unique
Features
- Ratiometric measurement permits
accurate measurement when lens contaminated up to 90%
- Zero and span checks on compliance
instruments
- Light intensity, upscale checks
|
- Selectable dust concentration
and/or opacity outputs
- Optional audit unit
- Blower systems not required since
air purge is sufficient
