Applications

Pneumatic Conveyor

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.

Diverter Gate

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.

Screw Conveyor Discharge

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.
