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)

• 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

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)

• 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)

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)

• 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
