ACF-10 Acoustical Flow Sensor for Solids

The ACF-10 is a self-contained acoustical sensor that detects the audible noise made by powders or grains in a pipe or conveyor. It may also be used to detect audible noise on mechanical equipment for preventive maintenance.

The solid state sensor detects acoustical vibrations by means of a sound pickup. If the audible vibrations exceed a predetermined limit, a relay output occurs. Because sound is transmitted very effectively by a metal or plastic pipe, this is especially suitable for pneumatic conveying. A lack of sound indicates a plugged pipe.
