ABSTRACT:
Airborne dust concentration in a silo or the like is measured by inducing flow in one or more Venturi nozzles (10) located in the area of airborne dust. A triboelectric sensor probe electrode (20) is located at the nozzle inlet section (12) and flow is induced by a feed of inductive air through an annular channel located in the wall of the nozzle downstream of the electrode.
