Applications
A tanker load of bulk solid material is being
pneumatically conveyed into a silo. The Sensor
detects the acoustic emissions generated by the
particles impacting against the pipe wall and the
output is used to activate the silo dust filter
system.
Recommended location is
any impact point along
the line, such as an
elbow.
Pneumatic Conveyor
A fibrous material is being delivered to a pelletiser by
means of a screw feeder. When loss of flow is
detected by the Sensor, an alarm in the control room
informs the operator of a possible blockage.
Recommended location is any point along the under
side of chute, where there is friction due to the flow
of material.
Screw Conveyor Discharge
The process material is stored in a hopper
and fed into the process through a diverter
gate. A Sensor mounted to each leg of the
diverter indicates the presence or absence
of flow in the open leg. Low alarm gives
early indication of problems in the diverter
gate or slide gate, or of blockage or mate-
rial shortage in the hopper.
