When silos are filled by mechanical conveyors, there is no pressure build up in silo. Though the system becomes simpler. Mechanical conveying systems such as bucket elevators and screw conveyors that fill silos in industrial plants generally have their own electrical controls with SCADA, DCS or similar systems. Implementing new silo equipment or several safety devices may require substantial effort. Depending on mechanical and electrical configuration of conveying system, a local control panel handling all silo functions might be much more convenient. Polimak silo filling control system panels have the capability of connecting to DCS or SCADA units. Start, stop, level and alarm signals can easily be transmitted between both units, providing cost efficient and practical way of implementation.
