Electrodynamic Probe Technology
PCME's range of probe type particulate emission monitors utilise PCME's unique Electrodynamic® measurement principle.
When the sensing probe is installed in the duct or stack, particles in the air stream interact with the sensing probe and a charge induction effect is analysed from the probe. Distributions in the particle stream result in a frequency charge induction response which is proportional to the concentration of particles.
Previous probe technologies, such as Triboelectric, relied on particle collision to created a measured signal. Electrodynamic® systems however, filter out the dc signal caused by particle collision, which makes the quality of measurement unaffected by build up on the probes which would otherwise cause zero or calibration drift.
Very low concentrations of particulate found even after the most efficient bag filter can be measured due to this unique Electrodynamic® technique.(<0.1 mg/m3)
These sensors are able to function in stacks and ducts up to 4.5 metres and process temperatures up to 800ºC.
Electrodynamic® technology also enables the use of patented fully insulated probes, essential for reliable measurement in high humidity applications (after process and spray driers).
