Goyen Mecair

PARTICULATE EMISSION probes

Particles in emission outlet streams of various manufacturing processes need to be measured to meet health, safety and environmental regulations. The Goyen Mecair range of Particulate Emission Probes such as the FFD, the FFA and the PEM, use a unique probe electrification technology which outperforms conventional triboelectric systems for emissions monitoring and broken bag detection.

FUNCTIONAL DESCRIPTION

UNIQUE PROBE ELECTRIFICATION TECHNOLOGY

The FFD, FFA and PEM utilize a unique probe electrification technology which provides much better performances than conventional DC triboelectric systems as well as alternative AC systems. This allows extending the velocity range over which the system has no cross sensitivity to changing velocity. Thanks to that technology, Goyen | Mecair probes are also unaffected by build-up of particulate on the sensing rod, thus eliminating signal drift concerns.
A charge signature is induced by particulates in the airstream interacting with the sensing rod. All three devices extract a specific frequency band from the induced AC current signature and filter out the DC current generated by direct particle collisions. In order to reject signals falling outside a pre-defined frequency range, the so resulting signal is electronically filtered, that is why these units are less susceptible to changes in particle velocity and are not affected by any particulate contamination on the sensing rod.


Also this technology, not relying on particles colliding with the probe, is able to measure a more representative area of the stack and eliminate the need of long sensor probe rods.
Thanks to the alarm delay feature, by properly setting the delay period, the system will exclude short term signal increases associated with pulse cleaning of filters.

MOUNT

The FFD, FFA and PEM heads are typically mounted through the wall of a duct carrying the moving particles so that the probe is exposed to the particles. The gas stream often exhausts to atmosphere (such as in a stack), but these emission monitors are equally suited to detecting particles in motion in a gas stream under other conditions, for example pneumatically-conveyed or gravity-fed particles.



APPLICATIONS
