ACF-10 Acoustical Flow Sensor for Solids

■

Operational Description

e 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.

e 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.

adjustments with (4) LED
indicators

■

Applications

e ACF-10 works best in
granular and powdered materials
that are hard. e rattling of
conveyed material on the pipe wall
will convey audible noise through
the pipe wall to the transducer. e
ACF-10 can also be affixed to motor
or machine bearings and can be
adjusted to provide an alarm when
excessive noise from the bearing
occurs. Calibration will require an
audible noise source comparable to a
faulty bearing.
