Working principle & design of Single Point Load Cell

The defining characteristic of a single-point load cell is its ability to accommodate off-center loading.

In general, maintaining the load and aligning it with the load cell can maximize the weighing accuracy of your single-point load cell.

If the weight moves off-axis, it introduces errors. On the other hand, single point load cells due to their geometric design allow for some flexibility and can thus maintain accurate weighing even if the weight is unevenly distributed.

What makes single point load cells are a perfect choice for platform scales is their ability to provide accurate readings even in versatile conditions.

Single point load cells are of enormous value as they eliminate the chances of any human error in placements.

Moreover, they help avoid the need for specialist equipment or training to simply get accurate weighing measurements.

Operating Principle:

A single point load cell, like any other technologically-advanced load cell, is a primary transducer that converts force/weight into an electrical signal.

They do so with the help of strain gauges, which are attached to the body of the single-point load cell.

The shape of a single point load cell deforms under load/weight and this change in shape is detected by the strain gauges. Afterward, these strain gauges distort in unison with the body, resulting in a change in voltage.

The voltage, strain gauges generated, is proportional to the initial weight/load and can be used to accurately calculate it.


Single point load cells come in a vast library of shapes and sizes to accommodate different types of applications and weighing equipment.

Every single point load cell features a geometrically precise cut-out of the body that’s known as “inner aperture”.

The inner aperture of a single point load cell visually distinguishes it from other load cells and makes it exceptional.

Moreover, it controls the thickness of the metal at various points across the single-point load cell body.

It’s the key to the load cell’s ability to accommodate off-center loading. The manufacturing material for single-point load cells is either high-grade aluminum or stainless steel.

Depending on the degree of environmental protection required by your single point load cell, they come in both potted or hermetically-sealed versions.

At CUBLiFT, we have a comprehensive catalog of single-point load cells accommodating both small and large volume orders.

The Evolution of Single Point Load Cell

A single point load cell is among the most precise weighing equipment worldwide.

In regards to other load cells or force sensors, a single point allows force to be applied at different points without falsifying the measurement results.

Moreover, it ensures accurate weighing measurements by the integrated parallelogram.

It serves thousands of high-precision weighing applications and is primarily used by plant engineers for manufacturing industries and for installation on industrial scales.

The History of Every Load Cell

In 1856, Lord Kelvin was the man behind the mechanism of a load cell, he discovered the electrical resistance of iron/copper wires increasing when they are subjected to tensile stress.

Later, Kelvin laid the foundation of strain gauge technology. That strain gauge technology, later on, became the basis for today’s high-tech single-point load cells/

Today, strain gauges have become an indispensable component for every industrial weighing equipment worldwide.

The ergonomic and exceptional design with an integrated parallelogram of single-point load cell is what sets it apart from other load cells.

With the parallelogram links and the resulting ability to precisely weigh loads off the platform, a single point load cell offers great value for a wide range of industries and applications.

The High-Precision Nature of Single Point Load CellThe High-Precision Nature of Single Point Load Cell Blog (2)

The two parallelogram links of a single point load cell which are fixed on both sides of its base body define its structure.

A pair of strain gauges are attached to each link. The parallelogram links are deformed in an s-shape when force is applied due to the thin spots.

Furthermore, its rectangular basic shape becomes a parallelogram link structure that ensures that off-center loads are compensated and that the load is always applied vertically.

The Basic Material for Single Point Load Cell

Stainless steel or aluminum are the two basic materials for single-point load cells for use in various applications with different environmental influences.

High-grade aluminum alloys exhibit high strength combined with low creep effects under load.

It helps eliminate any time-/temperature-dependent viscoelastic or plastic deformation under load.

Most importantly, high-grade aluminum alloys are the best base body material for single-point load cells.

The low aging properties of aluminum at typical operating temperatures -20° to 65° C increase the quality of load cell which also affects its performance.

Moreover, aluminum helps single point load cells achieve higher measuring accuracy as compared to stainless steel. Stainless steel, on the other hand, is extremely corrosion resistant to chemicals and improves the properties of single-point load cells against environmental influences.

Aluminum can be anodized to also improve the properties against environmental influences. Regardless of the choice of base body material, however, it’s extremely important to protect strain gauges to ensure accurate measurement results.

Protection of Strain Gauges

The strain gauges of single point load cell can be protected through silicon or metal encapsulation and this choice depends primarily on the environment in which the load cell will be used.

If its primary use is to operate in dry environments, metal encapsulation is a better option, or if the influence of moisture plays a subordinate role in the environment, silicon encapsulation is sufficient.

Strain gauges can be metallically encapsulated by being implemented in the area of the parallelogram links or with an additional deformation body.

Encapsulated single-point load cells featuring stainless steel as the base body material are predestined for environmental conditions with high demands on the degree of protection (up to IP69).

The foil of strain gauges is completely encapsulated in metal that increases their life-cycle, performance, and resistance against humidity to maintain accurate measurement results.

Application Areas of Single Point Load Cell

The most common applications of single point load cells are the following:

  1. Static Checkweighing: It offers highly accurate results for manual and automatic weighing processes in classic tasks such as Checkweighing.


  1. Dynamic Checkweighing: Single point load cells can take 100% control of the load to create productive reports and eliminate any chance of incorrect measurements in dynamic weighing processes.
