Dependable high-speed control with added value

for fast and precise filling and bagging

The dataPond 3F weighing controller is specially designed for dosing, filling and bagging granulates, free-flowing solids and liquids at very high throughput rates. It enables consistently accurate filling results to be achieved even in high-speed machines at cycle rates of over 2,000 fills per hour. It controls and monitors the entire dosing process and additionally offers many functions and setting options to solve the typical problems of filling processes.

Developed for stringent requirements, dataPond 3F provides an extended scope of adjustable functions, such as automatic dosing time optimization, automatic free-fall compensation in 3 modes with quick adaptation as well as special features like topping-up and fill-finish. Digital filters for sup­pression of vibrations and its smart program­ming with adaptive, predictive control plus comprehensive monitoring and statistical functions achieve maximum precision, speed and reliability of the dosing process.

Proven, powerful evaluation algorithms ensure optimal processing of the weighing signals and thus maximum measuring accuracy, even under difficult conditions. Special control algorithms then continually optimize and adjust the weighing process. As a result, dataPond 3F is able to flexibly adapt to changes in the product properties, such as material density or flow behavior, during the filling process.

From 220 parameter sets, presettings for different filling weights and products can be conveniently selected, allowing for quick format and product changes.

During operation, the dataPond 3F weighing controller automatically monitors a multitude of process parameters which help to optimize the system. Material flow rate, dosing times, filling weight, tolerances and process errors are, among others, recorded and evaluated. In addition, batch and product statistics as well as diagnostic data are logged on the controller. The dataPond 3F provides maximum repeat accuracy also for goods with critical filling characteristics – especially as disturbing influences are reliably suppressed, e.g. in the case of process fluctuations or switching operations.

The integrated alibi memory documents the last 60,000 filling results and meets the requirement for traceability of legal-for-trade weight values when used in the subsequent EDP system.

The weighing controller can be used stand-alone or networked and is customizable to different machine types. It is intuitive to operate, offers dialog-guided, digital adjustment and can also be configured as a multi-range or multi-interval scale. Up to 4 load cells can be connected.

Web server functionality

and various communication interfaces

The dataPond 3F can be flexibly integrated into almost any machine and control environment. For this purpose, the weighing controller offers 16 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 dataPond 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 dataPond 3F not only a reliable, but also a future-proof weighing controller for automatic scales.
