miniPond 3F
Filling Controller

Weighing control for filling and bagging processes at medium speeds, ensuring outstanding accuracy and repeatability even with difficult materials. It is versatile and can be adapted to the respective task via parameters.

Intuitive operation thanks to clear, application-oriented dialogs and displays. Commissioning, parameterization, remote access and remote maintenance also via a network using the integrated web server or fieldbus. Easy, flexible link-up to a PLC or control system.

Approved weighing controller

for use in filling and packing machines

Field-proven accuracy even under difficult conditions

when filling and bagging

The miniPond 3F, to which up to 4 load cells can be connected, is designed for filling and bagging solids, bulk materials and liquids at medium throughput rates. It controls and monitors the complete dosing process and ensures excellent precision and repeatability even with difficult materials.

The weighing controller can be used stand-alone or networked. It is intuitive to operate and can also be configured as a multi-range or multi-interval scale using dialog-guided, digital adjustment. The controller offers numerous customization possibilities for different machine types and is able to flexibly adapt to changes in the respective product properties, such as material density or flow behavior, during the filling process.

From up to 7 parameter sets, presettings for different filling weights and products can be conveniently selected. Digital filters for optimum processing of the weighing signals and proven, powerful evaluation algorithms ensure maximum measuring accuracy, even under difficult conditions.
During operation, the miniPond 3F weighing controller automatically monitors a multitude of process parameters which help to optimize the system. Among others, filling weight, tolerances and process errors are recorded and evaluated. In addition, data such as counts and totals as well as diagnostic data are logged and documented. The miniPond 3F provides maximum repeat accuracy also for goods with critical filling characteristics – especially as disturbing influences are reliably suppressed, for example, in the case of process fluctuations or switching operations.

Web server functionality

and various communication interfaces

The miniPond 3F can be flexibly integrated into almost any machine and control environment. For this purpose, the weighing controller offers 8 digital I/Os, COM port, Ethernet interface, Modbus protocol and optional fieldbus interfaces such as Profibus, Profinet or EtherNet/IP.
The integrated web server enables access via a browser, e.g. for setting parameters, for adjustment as well as for functional testing, and allows targeted fault and process diagnosis directly from the device. Also data backup, firmware updates and remote main­tenance can be carried out comfortably via the web interface.

Remote diagnostics and remote maintenance of devices at other locations via the Internet are also possible (if enabled accordingly). At the same time, the miniPond 3F can also be integrated into Industry 4.0-compliant structures and applications via the fieldbus, for example in condition monitoring applications on the supervisory control level or in the cloud. This makes the miniPond 3F not only a reliable, but also a future-proof weighing controller for automatic scales.
