Powerful high-speed checkweighers for maximum weighing accuracy
Your dynamic scales with precision
In most production facilities, dynamic scales are primarily used to check the weight of goods during dispatch or at the end of the packaging process for final verification. This is now considered standard practice for quality assurance and is prescribed in numerous industry guidelines. High-performance checkweighers are therefore a must. Nowadays, no manufacturer can (or should) afford to compromise on weighing accuracy.
At the same time, many items must pass over the weighing belt every second in order to ensure the best possible throughput rates. This is precisely the reason why we developed our automatic high-speed checkweighers. For us here at Wipotec, high speed and dynamic weighing goes hand in hand with precision. Whether you need supplementary weighing systems, ready-made complete solutions or a customized multi-scale system – the choice is entirely yours. Modularity is the key to flexibility.

Application: How Wipotec’s dynamic scales check up to 640 Manner wafers per minute
Dragées, pralines, sponge and cookies are just some of the confectionery products that the Austrian family business Josef Manner & Comp AG distributes in addition to the world-famous waffles. Such a wide range of products often requires customized solutions for the production and packaging processes. To maintain its own standards, the company relies on high-performance checkweighers from Wipotec. 24 of our checkweighers are in continuous operation at the plant in Vienna alone, where around 150 tons of raw materials are processed into confectionery on regular days.
These volumes can only be guaranteed with the help of dynamic scales that operate constantly at high speed. Without compromising on weighing accuracy, our precision checkweighers at Josef Manner regularly achieve throughput rates of well over 500 items per minute. The confectionery producer is highly satisfied with the system. As a result, each packaging line now includes at least one Wipotec checkweigher. Because we know the food industry inside out. For decades, our team has been developing special solutions for the food sector to ensure that all regulations are always met.
Reliable control with high speed at Manner
In any case, Josef Manner no longer wants to do without its high-speed checkweighers, which are an integral component of their complete production process. As a result, we work closely with our service team, who are always on hand to assist whenever a problem occurs. In Austria, we usually entrust Bauer Systemtechnik with this task. As always, we guarantee quick reaction times and support the use of our dynamic scales around the world. Precisely how the weighing control operates at Josef Manner and why automatic weighing is absolutely vital is explained in our more detailed application report:
Wipotec EMFR Weigh Cells – Highest weighing accuracy for high-performance checkweighers
Each element of dynamic scales must do its job. For a high-speed checkweigher to consistently give precise weighing results during regular operation, the underlying weighing technology must be right. This is one of Wipotec’s specialties: we design and build all of the components for our precision checkweighers and integrate them into our own weighing software. This allows us to consistently achieve a vertical integration of over 85 percent.
At the heart of these efforts is, of course, the Weigh Cell, which has the most crucial task: checking the weight of your goods. Our high-performance checkweighers follow the principle of electromagnetic force restoration (EMFR), which maintains the usual weighing accuracy of the weighing belt even at high speed. This applies to normal production conditions as well as in extremely wet environments. So if your business is subject to special hygiene requirements, we recommend taking a look at our Wash Down checkweighers.
Without going into too much detail, consider dynamic weighing with an EMFR Weigh Cell from Wipotec as a refined version of the traditional beam balance. The weight of your products triggers a mechanism within the cell, whereby the determined result is passed on to your system by means of a magnetic field. The outstanding weighing accuracy of our precision checkweighers stems from its high response sensitivity and linearity. Extremely fast settling times in turn enable application in the high-speed range.
Accurate high-speed checkweighers with AVC technology
Precision checkweighers do not work in a vacuum. The reality is that your dynamic scales or multi-scale system are constantly exposed to various disruptive factors that can range from harmless to extremely troublesome. On the one hand, heavy products moving at high speed along the conveyor belt of your scales generate vibrations, which negatively affect the weighing accuracy of the systems. On the other hand, the immediate environment has an effect on the weighing belt; you may even be using heavy machinery close by that causes slight vibrations. Furthermore, your weighing solutions can become much less stable when they move further away from the safe ground, for example when using work platforms.
In this case, you require particularly powerful checkweighers whose weighing mechanism eliminates such annoyances when measuring weight. With Wipotec you are well prepared. We incorporate Active Vibration Compensation (AVC) into your weighing system for this specific purpose. The sensitive sensors compensate for external influences in real time, ensuring the required weighing precision. Wipotec offers a high-speed checkweigher that is also appropriate for non-vibration-free environments. Would you like to find out more about how our dynamic weighing technology works? We would be pleased to present the Wipotec weighing principle to you in detail. Our team is also available to answer any questions you may have at any time:
Multitrack and Multilane for the fastest precision checkweighers
How can dynamic scales, which already push currently conceivable weighing technology to its limits, gain even more speed? It’s fairly simple – additional conveyor belts and Weigh Cells are integrated into the automatic checkweigher. Multitrack and Multilane transform a single checkweigher into a holistic multi-scale system capable of handling both small and large products without any issues. As a pharmaceutical company, for example, you have to put numerous vials or bottles through their paces on a daily basis, even though they are not very heavy and require maximum precision. We have combined dynamic checkweighers on up to 18 lanes without compromising on weighing accuracy.
Perform a filling level and completeness check at the same time and in parallel on several weighing belts. This is high speed on a new level. Our Modular Multi-lane System (MMS), which enables you to create your own weighing solution, deserves special recognition. In consultation with our experts, you define the number and center-to-center distance of the lanes and receive from us precisely the high-speed checkweighers that are best suited to your application. This flexibility defines Wipotec’s modular design. Concentrate on weight checking or add other modules such as metal detectors or other optical inspection systems.
