Loading scale VW-500
The VW-500 loading scale has been developed for modern silo logistics. This system is indispensable due to the very high levels of accuracy it achieves. For standard products such as granulate, sugar, etc., these are +/- 20 kg for a loading quantity of 25,000 kg.
This prevents the vehicle from being overloaded. It is also possible to load individual compartments of the vehicle with precision.
The system is approved for calibration in accordance with MID 2014/32/EU and eliminates the need for a second weighing of the vehicle. Order management can be automated by connecting to customer databases or software systems such as SAP. All weighing data is stored in an alibi memory for at least 3 months. Depending on customer requirements, specifications or performance, the system can be integrated into existing silo systems.
Einsatzgebiete
Control
The scale has a self-sufficient control system with integrated, calibratable weighing electronics and a Siemens S7 PLC. The scale can be operated entirely via the touch panel. The connection to the silo control system is made via plug contacts with the signals “Silo open” and the feedback signals, as well as via the corresponding approvals.
Silo connection
The silo connection can also be made in a variety of ways. Here, there is the option of a press-fit device that presses firmly against the silo outlet. Alternatively, there is also a pipe system that slides around the silo outlet pipe without a fixed connection. A positioning accuracy of at least +/-50 mm is guaranteed.
Weighing system
In such systems, the weighing vessel is usually designed with a nominal filling capacity of 500 kg. The vessel outlet must be sufficiently large to allow rapid emptying. All weights are recorded in a manner that allows calibration. The weighing container is connected to three high-precision ball supports.
