Description

The FFA utilizes 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, the FFA is 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. The FFA extracts 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. Thanks to that, Goyen | Mecair filter failure alarms are less susceptible to changes in particle velocity and are not affected by any particulate contamination on the sensing rod.
