The Evolution of S-Type Load Cell


Introduction to S-Type Load Cells

S-type load cells are exceptional and highly productive for tensile applications where you will experience static and dynamic loads. S-type load cells make the mechanical-to-electronic conversions extremely easy and accurate.

Unlike any other load cell, the S-type load cell features metal foil strain gauge technology. This load cell is a perfect choice for industrial weighing applications because of its incredibly high accuracy and resistance against critical environmental conditions.

These low-cost and high-performance load cells come with a 6-foot strain relieved integral cable with pigtail leads for electrical interface. The state-of-the-art technology and design of S-type load cells make them the perfect load cells for nearly every modern weighing equipment.

With capacities up to 30t, we offer a wide variety of S-type load cells made from alloy steel and stainless steel.

 Advantages of S-Type Load Cell

S-type load cells are extremely popular because of the four primary reasons:

  1. They’re economical (typically <$300 for capacities up to 3 tons)
  2. Easy to mount (single-threaded hole on both sides of the load cells)
  • Precision and accuracy (they’re highly accurate up to ±0.025%)
  1. They’re universal (maintain high performance in both tension and compression)

S type load cells don’t allow for any off-center or off-axis forces and deliver accurate weighing measurements.

Moreover, the following are some secondary benefits of S-type load cells:

  • They’re extremely versatile
  • High endurance
  • High & low capacity options
  • Compact design; makes it suitable for tight environments
  • Suited for both compression and tension applications
  • Availability in imperial dimensions and capacities
  • High performance in cost-effective manners
  • Availability in stainless steel and alloy options
  • Outstanding reliability and long term stability
  • Suitable for harsh & severe industrial environments
  • Temperature-compensated
  • Feature a stable system with no moving parts and linkages


How Does S-Type Load Cell Works?

Tension load cells or S-type load cells are predominantly used for measuring tension or pulling force.

Moreover, many sub-types of these load cells can measure compression too, which makes them extremely versatile due to having bi-directional sensitivity.

The name of the s-type load cell resembles its ergonomic design which is based on an upper and lower arm to help align the mounting points to the central axis.

Working Principle of S-Type Load Cell

S-type is based on modern load cell technology to convert force or weight into an electrical signal.  The main body of S-type load cells deforms slights when experiencing a load.

The strain gauges on the body of the s-type load cell are firmly bonded helps alter the electrical resistance to a voltage signal.

The voltage signal it generates is proportional to the initial force or weight.

Design of S-Type Load Cell

The S-type load cell is typically integrated into the supporting apparatus of particular weighing equipment and designed to suit applications that involve suspended weights.

The lower and upper limbs of the s-type load cell ensure that its mounting holes are in-line with the central axis.

The ergonomic design of these load cells makes them specialized beam load cells. Neither end is fixed in an S-type tension cell. Furthermore, its one end is connected to the apparatus below via the lower arm.

There’s a pull-up on one side of the central bar of this load cell whenever it experiences tension and an equal pull-down on the other end of the central bar. Afterward, strain gauges pick the difference across the central bar that causes the deformation.


Popular Applications of S-Type Load Cells

The primary use of S-type load cells is in mechanical-to-electronic conversions for a number of weighing and general force measurement applications.

The following are some of the extremely popular applications for S type load cells:

  • Industrial control/feedback
  • Dynamometer testing machines
  • Industrial food processing
  • Crane scales
  • Structural performance testing on automotive systems
  • Tank weighing
  • Automotive component lifecycle
  • Mechanical overload protection
  • Hanging scales
  • Structural performance testing
  • Hopper scales
  • Material strain testing
  • Material strain testing of elastomers and polymers
  • Shore hardness & weighing


The Advancements in the S-Type Load Cell Manufacturing

The primary objective of S-type load cells is to measure tensile forces, but also are suitable for compressive force measurement.

They’re ergonomically designed to withstand harsh ambient conditions and are mainly used in industrial applications.

S-type load cells meet the IP65 to IP68 requirements from the following protections:

  • Dust ingress
  • Slash water
  • Splash water
  • Temperature immersion

S-type load cells are chosen based on the following key parameters:

  • Rated load
  • Limit
  • Breaking load
  • Minimum scale division

The results are indicated in Newton where the load cells are to serve as force transducers.

Load cell manufacturers are able to determine its accuracy and permissible tare weight based on the above data.

At CUBLiFT, we manufacture s-type load cells that are verifiable, as most weighing systems need verifications.

Functions of S-Type Load Cells

The middle bar of the S-type load cell is the spring body of the load cell. It restores its shape once the pressure is released and deforms under pressure to record tension.

It’s also the core component of S-type load cells because it measures the weights and defines its accuracy. A strain gauge attached to the metal performs this deformation process and generates electrical signals determining the weight values.

The following are the primary parts of a standard S-type load cell:

  • Mounting hole
  • Strain gauges
  • Upper arm
  • Central beam
  • Protective potting
  • Lower arms

It’s known to be an ideal solution for use in critical industrial environments due to its high IP68 degree of resistance.

The connection cable which outputs the data to be observed can be permanently protected by a connection adapter for viable protection systems, which is available as a custom option for the s-type load cell.

At CUBLiFT, we increase the performance of our s-type load cells by hermetically encapsulating them to have a robust, stainless-steel measuring body to permanently withstand humid and harsh environments.

Its low profile stainless steel design with accuracy ranges from ±0.28 % up to ±0.02 % (enhanced) and load ranges from 5 kg to 30 tons, making it the most versatile and universal load cell.

It can fit into systems with limited space or tight clearances perfectly and offers stability and reliability under rugged operating conditions.


Selecting the Right S-Type Load Cell Technology

Load cell selection concerns itself primarily with the right capacity, accuracy class, and environmental protection.


The capacity requirements of your load cells require a fundamental understanding of the following:

  • Load related terms for load cells
  • Load related factors associated with the system

Furthermore, these load-related terms for your s-type load cells feature the following:

  • Load cell measuring range
  • Safe load limit
  • Ultimate overload
  • Safe sideload

A load cell performs exceptionally accurately within specifications until the safe side load limit or safe load limit is passed. At the ultimate load limit, the load cell can physically break. The following factors contribute to the weight load on the load cells:

  • Dead load
  • Zero tracking
  • Maximum scale capacity
  • Initial zero settings
  • Location

In addition to these, it’s also important to derate your s-type load cells meaning use higher capacity load cells because of the following reasons:

  • Off-center distribution of dead load
  • Off-center loading to the scale
  • Shock loading
  • The possibility of an overload weight
  • Dynamic influences



The “% rate output” of all the s-type load cells is mentioned in their specifications.

The accuracy of a load cell sensor is determined through its %RO (Rate Output). Having an error of ± 0.5%RO of a load cell with 10,000 kg capacity means it has a resolution of ± 50kg.

Load cells are ranked according to their overall performance capabilities defined by their % rate output or resolution.

These accuracy classes can be related to standards that are used in legal for trade weighing instruments or defined by the individual load cell manufacturer.

Depending on the standard and the performance of a particular load cell type, it has given an accuracy grade.

Environmental protection:

It’s important to choose the right load cell that offers the required environmental protection and sealing standards.

It’s crucial for a load cell manufacturer to have in-depth test procedures and standards to define load cell and weighing system performance to determine its accuracy and precision.

However, there’re no standards to define the suitability of a load cell for specific environmental conditions.

However, we are able to manufacture a fully-customized load cell for your custom environment, equipment, and other needs.

The Selection Criteria of S-Type Load Cell

The S-type load cell can be extremely productive for your applications, and to find out how there’re many important factors to consider.

  1. Waterproof load cells: Wet environments need higher water-resistant in their load cells. We offer hermetically sealed IP68 rated waterproof s-type load cells.

Your Industrial Partner for Stable and Accurate Measurement


S type load cell, or S beam load cells made from CUBTEC, as the name suggests, it is compression tension load cells.

It means that both tension and pressure can be measured by an s-type load cell.

The shape of the load cell sensor is s-shaped, we usually call it an s-beam load cell sensor.

The s-type load cells are one of the first invented force sensors, so it is very widely used in various industries and has very high accuracy as well.

Looking at the S-type load cell, you can find that Its force area is on the upper and lower rectangular faces, which means when applying pressure, we just need to apply the force on the two rectangular surfaces.

By taking a balance weight and placing it directly on one side face of the S-type load cell sensor, we can measure the pressure force imposed on it.

When measuring tension force, the S-type load cell sensor has two threaded holes on the top and bottom, so we can fix our load pins or load shackles or other work pieces on these two threaded holes and pull them against each other to measure the tensile force.

S-type load cell sensors are available in different sizes, for example, the small size can reach 19.1 × 16 mm, and the large size can reach 50 × 66 mm or more.

Because the structure and size of the load cell sensor are different, the load capacity is also different, corresponding to different use scenarios.

From mini load cells to large capacity up to 10000kg, you can find the right S beam load cell to fit your specific needs. The S-type load cell is really useful in various industries. Contact us for details.

Is an S-type load cell a type of tension load cell?

YES. An S beam load cell belongs to the category of tension load cells.
With the S-shaped design, it is capable of measuring both tension (pulling) and compression (pushing) forces.
But a tension load cell is specifically designed to only measure tension or pulling forces. It cannot measure compression forces like an S-type can.

What is FSO in Load Cells?

FSO stands for Full Scale Output, which is a term used to describe the maximum output signal of a sensor, such as a load cell, within its rated capacity.
Take our PDLY-103 for example, it has an accuracy of ±0.03% FSO, means the possible error in measurement would be:
0.03% of 100kg = 0.03/100 x 100kg = 0.03kg
This means the readings from the s beam load cell will have a potential/possible error margin of plus or minus 30 grams on a 100kg load.
