B.V. has developed a range of solutions
to monitor & totalise the flow rate of bulk products while they are
transported along belt conveyors.
The unique PENKO way of measuring high speed and high resolution
immediately detects any changes in the flow of mass.
Belt weighers are automated systems
designed to control, regulate and totalize continuous flow of bulk material.
For this purpose a section of the belt is usually set up for weighing: (m/l)
mass per unit belt length. A transducer establishes the displacement length
(l). Multiplying the mass by length (m/l x l = m) measures in the mass
transported by the belt. At the same time the belt speed and the displacement
per time unit is repeatedly calculated (l/t). Subsequently the flow of mass is established
(m/l x l/t = m/t).
During the process, the instruments offer a wealth
of information including:
- mass flow
- belt speed
In addition, the product flow to the belt can be
regulated by an on/off switch and/or by regulating the speed of the belt. This
allows for the control of the flow of mass and measurement of the current mass.
outputs of the controller are can be used for example to switch motor drives,
while analogue outputs can control the speed of the belt or a transporter
screw. The mass can be controlled on the entire belt or on just a section of
the belt, depending on the application.
Frequently these systems are
used for bulk loading, in other words, for trade applications, they are fully
certified in accordance with the current European Directive MID and
Once bulk material has been charged or discharged, it
is very costly to recheck it in the event of inconsistencies. Therefore,
totalizing and storage of this data is critical.
