Find the right Weigh Cell

Our Weigh Cells are used in all industrial production processes.

In addition to integration in checkweighers and filling/dosing lines, they are also installed in packaging machines of all kinds. Weigh Cells prevaildue to:

  • maximum accuracy
  • guaranteed long-term stability
  • excellent responsiveness
  • first-rate linearty
  • fastest settling times

Unshakeable
Weigh Cells for Production

Precision is the be-all and end-all when weighing products. Regardless of whether you manufacture pharmaceuticals, produce food or have to weigh chemical products – our Weigh Cells guarantee this precision when acquiring your product weights. 

If you are looking for a technical solution with which you can achieve the highest quality in product manufacturing, enabling you to make an important contribution toward customer satisfaction, choose WIPOTEC Weigh Cells for a future-oriented investment.

You will notice that we understand our craft – the development and production of Weigh Cells – at the latest when you integrate one of our Weigh Cells into your automated and very fast production. Based on the principle of electro-magnetic force restoration (EMFR), Weigh Cells ensure precise weight measurements, even at very high speeds. And in the event that your weighing process is subject to external influences, such as vibrations from adjacent production lines, here too you can rely on the most accurate data. Thanks to our Active Vibration Compensation (AVC), Weigh Cells filter out disturbance variables. For even greater reliability and product quality even in highly dynamic production processes.

    Weigh Cell FAQ

    What is the difference between a Weigh Cell and a Load Cell?

    Both Weigh Cells and load cells are used to measure weight; they are diverse in their technical design. The load cell version is based on measuring with a strain gauge which is mounted on a spring element. This principle is used when the time factor plays a subordinate role in weight measurement, such as in scales used in the retail sector. If it is necessary to weigh products within an automated, often very fast production process, Weigh Cells which work on the principle of electro-magnetic force restoration (EMFR) are used. They deliver precise weight measurements even at high speeds. It is possible to measure weights from as low as one (micro)gram or (milli)gram but also as high as 50 kg or 200 kg, for example. 

    How does a Weigh Cell work?

    The classic design of a mechatronically complex Weigh Cell (EMFR) is made up of the balance mechanism, a position indicator, a controller, an electro-magnetic drive (coil and permanent magnet) and a display unit. For example, a CNC-machined monoblock, made of aluminum, can form the basis of the design. The Weigh Cell itself can be compared in its functionality to a simple beam balance: If a weight is placed on one side of the beam (coil arm), a coil attached to the opposite side of the weighing beam attempts to move out of the magnet's magnetic field. A photoelectric beam (zero indicator) detects this deviation and exactly the amount of current required for balancing the beam is transmitted through the coil. As the current is proportional to the weight and can be measured via a resistor, it can be converted into a digital signal which is used for further processing. This operating principle ensures that Weigh Cells which work according to the principle of electro-magnetic force restoration ensure high resolutions and good repeatability in equal measure and have short measuring times. The magnet system and the electronics, such as the scanning circuits, controller and filter boards, as well as specific communication interfaces, form the essential basis for extremely short settling times and sampling rates of 1 millisecond which are required above all in highly dynamic weighing processes. 
     

    Where are Weigh Cells and Load Cells used, respectively?

    Depending on their design, Weigh Cells and/or Load Cells are used in almost all industries. Typical measuring tasks for strain gauges are acquiring the weight of a container on a one-off basis or continuous weighing, e.g. to record the inflow and outflow of a material into or out of a container (storage tank) using a load cell, as is required in the chemical industry, among others. Dynamic weighing and weight determination of difficult drugs, sensitive foods or the smallest electronic components using EMFR based Weigh Cells can be found everywhere in the manufacturing industry where the lowest weights correlate with the highest production speeds, such as in the automotive sector, electronics production, the pharmaceutical industry, food production or aerospace technology.
