Load cells are designed as a special form of force transducer for use in weighing technology. The calibration is made in grams, kilograms or tons, not in Newton, as is usual in force measurement. Integrated strain gauges transform the elastic deformations of the load cells, caused by the weight loads, proportionally into electrical signals. This enables a very high measurement accuracy of between 0.01 % and 0.05 % Fnom.

Through the integration of tecsis, an experienced and global measurement technology manufacturer, WIKA offers a high-quality product portfolio, from platform, through bending beam and shear beam to compression force load cells.

What is the advantage of weighting technology?

For many applications, it is advantageous if level measurement does not require intrusion into the tank or vessel. Thus the measurement takes place independently of the material and its properties. For the different vessel geometries, for example of silos, containers or reservoirs, we offer suitable load cells that fulfil these requirements – regardless of the type and character of the media. Whether liquid or solid, aggressive, generating foam or dust, steaming, conductive or non-conductive, with small or large grain size: Factors like these are irrelevant. Also, neither hoppers nor conical piles, bridging, caking nor even agitators affect the measuring result.

Gravimetric level measurement is also in demand in temperature-critical applications and where high durability and robustness are required, such as in the steel industry.

What are single point load cells in weighing technology?

Single-point load cells are by far the most commonly used load cells, with a wide range of possible applications. They are also referred to as platform load cells and are particularly suitable for use in scales and weighing equipment in which the weight determination is not predictably centric.

Their installation and use is proven to be very simple: As can be seen from everyday bathroom scales, they are insensitive to side and corner loading. Typical areas of application are in the logistics sector, in machine building or in the packaging industry.

What are bending and shear bars used for in weighing technology?

Bending and shear beams are often used to determine the weight of small and medium-sized vessels. In these measurements, high accuracy, high ingress protection, robustness and low costs play a major role.

The bending beam is fixed using two mounting holes at the transducer side with the cable outlet. At the opposite side, the force is applied perpendicularly to the measuring unit, centrically and without any shear force. Since it is manufactured completely from stainless steel, trouble-free operation is possible, even under unfavourable environmental conditions.

In which sectors is weighing technology mainly used?

WIKA weighing technology is used in a wide variety of industries and applications. The following examples illustrate this diversity:

  • Medical engineering:
    Our products, for example, help to monitor the weight of newborns in incubators.
    In blood mixing scales, load cells are used for the exact delivered volume of blood donations.
  • Agricultural technology:
    The levels of aggressive media, such as in silos, can be precisely measured by our weighing technology.
    In agricultural engineering, for example, exact weighing of the harvest yields on a combine harvester is made possible.
  • Machine building:
    Our load cells are used, for example, in heat sealing devices. Platform load cells measure the optimum contact force for the heating rail.
