How does a Weigh Cell work?
The classic design of a mechatronically complex Weigh Cell consists of
- the balance mechanism
- a position indicator
- an electromagnetic controller
- a digital interface
A CNC-machined monoblock made of aluminum, for example, can form the basis of the design.
Wipotec Weigh Cells use the principle of EMFR. In technical literature, this technical specification is also referred to as electromagnetic force restoration (EMFR).
These weight sensors are comparable to a simple beam balance. If a weight is placed on one side of the beam, the coil attached to the opposite side of the weighing beam attempts to move out of the magnet’s magnetic field.
A photodiode detects this deviation. Exactly enough current is then sent through to the coil to ensure that it is balanced. The current is proportional to the weight force and is measured using a measuring resistor. After further processing in a microprocessor system, a digital signal is produced, which can be processed further, for example, into weight data.
With this EMFR operating principle, we ensure that our Weigh Cells guarantee high resolutions, good reproducibility and short measuring times. The basis for the extremely short settling times and the sampling rates of just one millisecond are due to
- our unique fast-sampling technology
- the precision of our monoblock system and
- the internal controllers and filter stages
This is why our Wipotec EMFR Weigh Cells are perfectly suited for all highly dynamic, extremely fast and extremely accurate weighing processes, for example in the pharmaceutical industry, in food production, for aerosols, in cosmetics or in mechanical engineering.

What are digital Weigh Cells?
Digital Weigh Cells are electronic sensors that are used to measure weight. When it comes to speed, digital beam balances or EMFR scales have a clear advantage, as their measuring times are significantly shorter than those of strain gauge scales thanks to the extremely short settling time. They are therefore mainly used in high-speed industrial applications such as in the pharmaceutical, healthcare and cosmetics industries, in the food industry or in chemical manufacturing and filling processes, especially in the construction materials and minerals sector. But high speeds are also important for courier, express and parcel services (CEP), as well as the mail order and intralogistics sectors.
Special digital and compact multilane Weigh Cells from Wipotec can also be supplied with electronics in a separate housing. Especially in multilane applications, this prevents the formation of heat, which is detrimental to fast and highly accurate weighing, as there is no need for complex cooling.
As an alternative to the electronics box, Wipotec Weigh Cells can be operated on MMS2 system components (MMS2 = Modular Multilane System). All components are designed with IP65 protection and so do not need to be installed in a separate control cabinet. Multilane modules designed in this way can be configured individually: Thanks to the modular system, users can simply plug in the electronic modules for the Weigh Cells at lane level – and connect an AVC sensor. Such digital Weigh Cells provide reliable and accurate measured values even when exposed to severe vibrations, as may occur in multilane, high-speed production systems.

Where are weigh modules used?
Weigh Cells are used in almost all industries.
EMFR Weigh Cells can be found wherever the lowest weights meet the highest production speeds. Typical sectors include the pharmaceutical industry, the automotive sector, electronics manufacturing, the chemical industry, aerospace technology, the logistics sector and, of course, food production:
- E-mobility: Platform Weigh Cells weigh the various battery components, for example.
- Healthcare: The weight indicates whether packed products are complete.
- Chemicals: Used in belt scales, platform Weigh Cells monitor manufacturing and filling processes for dynamic weight determination in the continuous measurement of bulk goods.
What is the difference between a tension load cell and a compression load cell?
Tension load (tension force) cell
Tension load cells are used for static weighing tasks in the process industry and for conveying applications as well as high-precision dosing. This includes, for example, filling level measurement of suspended containers. With the appropriate interfaces, the weighing electronics provide digital weighing results for all common process management systems.
The load is usually applied to load cells from above. Modules from Wipotec, which operate using the electro-magnetic force restoration (EMFR) principle, can also be used to measure tensile forces. Load introduction from above is then replaced by tension force from below. Wipotec Weigh Cells are mounted upside down to measure tensile loads. The product to be weighed can be attached directly to the Weigh Cell in the load direction.
Compression load (compression force) cell
Compression load cells are among the most widely used types: They are usually positioned beneath the object to be measured. Wipotec’s compression load Weigh Cells operate using the principle of electro-magnetic force restoration (EMFR). Due to their operating principle, such special modules offer high resolutions and good repeatability together with the shortest measuring times. They can also accurately measure very small weight forces. This is why they are used by preference in precision and fine balances as well as analytical and microbalances.
An optional integrated test weight allows a self-check at any time to verify the functionality of the Weigh Cell. Depending on the specification, Wipotec compression load Weigh cells also meet the washdown specifications of protection classes IP65 and IP69K. This makes cleaning the scales considerably easier.
What makes Wipotec weigh modules so special
Measured values in the shortest time
Each Wipotec Weigh Cell consists of a monoblock that is milled from aluminum. They are based on the principle of electro-magnetic force restoration (EMFR) and work like a mechanical beam balance whose minimum deflection is compensated electrodynamically. Our models deliver very accurate readings in the shortest possible time. They do not require a spring element that deforms under load like strain gauge load cells.
Unwavering precision
Our solutions are perfect for areas where shocks are an everyday occurrence, as they are equipped with AVC (Active Vibration Compensation) technology. AVC is a sensor-based measurement technology that filters out shocks and vibrations in all three spatial axes, without losing time or accuracy. Weigh Cell modules equipped in this way are therefore perfect for demanding production environments or sorting centers. In these environments they secure competitive advantages with their unfailing precision.

Weigh Cell compact facts
What is a Weigh Cell?
Wipotec Weigh Cells measure weights in micrograms and milligrams – or even larger weights from 50 kg to 120 kg. They are installed in a wide range of scales.
- Strain gauge load cells use a strain gauge attached to a spring body for measurement.
- EMFR Weigh Cells use the principle of electro-magnetic force restoration (EMFR) and are therefore particularly fast and extremely accurate.
What does a Weigh Cell measure?
A Wipotec Weigh Cell module measures weights and forces – it reacts to pressure or tension from micrograms up to 120 kilograms. To do so, it uses the principle of electro-magnetic force restoration (EMFR). This is why a Wipotec Weigh Cell works quickly and precisely.
How does an EMFR Weigh Cell work?
An EMFR Weigh Cell uses the principle of electro-magnetic force restoration (EMFR). In its functionality, it is similar to a simple beam balance. If a weight is placed on one side of the beam, a coil attached to the opposite side of the weighing beam attempts to move out of the magnet’s magnetic field. This deviation is detected by a photoelectric beam (zero indicator). Following this, exactly enough current is sent through to the coil to ensure that it is balanced. As the current is proportional to the weight and is measured via a resistor, it can be converted into a digital signal and further processed.
Where are Weigh Cells used?
Weigh Cells are indispensable in almost all industries: SG load cells, which work using a strain gauge, are often used to measure weights once.
However, as soon as the weighing process is dynamic and fast, Weigh Cells that work according to the principle of electro-magnetic force restoration (EMFR) are the solution: These models can process the lowest weights at the highest production speeds. Such processes exist in the food industry, in the production of electronic components or in the pharmaceutical industry, for example. These products are also used in aerospace technology.
What types of Weigh Cells exist?
Weigh Cells are available in many different designs – always matching the type of scale, such as platform scales, floor scales, bench scales, static scales, checkweighers or catchweighers. The most important parameter for the development of custom-fit modules is firstly measuring accuracy. However, the measuring speed, the height of the weights and the type of measurement (tension, compression, dynamic or static) also play an important role.
What is a digital Weigh Cell?
Digital Weigh Cells are a special type that process and evaluate weights digitally. These special modules are available in two designs:
- In strain gauge scales, the geometry of a spring element changes under load. This elastic deformation is recorded by a strain gauge (SG) and converted into an electrical signal.
- EMFR scales function like a mechanical beam balance whose deflection is compensated electrodynamically with the aid of a magnetic coil. Digital Weigh Cells from Wipotec operate using the principle of electro-magnetic force restoration (EMFR) – in the weight range between 1 microgram and 120 kilograms.
What is the function of a Weigh Cell?
Such a module is at the heart of every precision scale: It measures the weights placed on or attached to these scales extremely accurately.
What is a platform Weigh Cell?
As the name suggests. platform Weigh Cells are mostly used in platform scales. Such special scales are important for dynamic filling, packaging and weighing processes in the food and pharmaceutical industries. In these high-speed production lines, in addition to speed, maximum robustness and easy cleaning are particularly important. This is precisely what Wipotec Weigh Cells offer.
