The History of Load Cells

Modern load cells operate by utilizing strain gauges arranged in a Wheatstone configuration. This technology owes its development to two key innovations: the Wheatstone bridge equation and the strain gauge itself. Sir Charles Wheatstone refined and popularized the Wheatstone bridge equation in 1843, establishing the principle of differential measurement. However, this equation’s practical utility was limited until the invention of the strain gauge. Prior to its development, large loads and industrial items were typically weighed using mechanical lever scales.

In the 1940s, the strain gauge emerged, marking a significant advancement. Initially, researchers introduced the first bonded resistance wire strain gauge. The combination of this innovation with the Wheatstone bridge equation led to the creation of load cells. Despite having the necessary components, engineers faced challenges in scaling production due to limited electronic technology and funding. However, as technology advanced and feasibility improved, the adoption of load cells skyrocketed, fueling ongoing growth in the industry to the present day.


Production Process

Load cells are crafted through principles involving mass measurement under fluid pressure, elasticity, magnetic effects, piezoelectricity, and zero-gravity conditions. They consist of two primary components: the sensing element and the circuit, typically accompanied by connecting cables.

The sensing element typically comprises a strain gauge, a compact device that detects strain, weight, or force by converting internal deformation into electrical signals. Occasionally, the load cell may employ a piezoelectric sensor instead, utilizing piezoelectric crystals to measure strain, movement, weight, and vibrations. This category includes pressure and force transducers, which, like load cells, gauge applied force, pressure, and strain in contexts such as gas and liquid pressures, and altitude. The circuit links these sensors or gauges to various points within the load cell, while cables, if employed, connect transducers to instrumentation.

Material Design

Load cells can be crafted from diverse metallic materials, including tool steel, alloy steel, stainless steel, and aluminum, tailored to the specific requirements of the load cell. Manufacturers select materials based on the intended use, prioritizing characteristics such as lightness, strength, electrical and thermal conductivity, aesthetic appeal, ease of machining, corrosion resistance, resilience at very low temperatures, and malleability.

Design Considerations and Customization

In crafting a load cell, manufacturers must navigate a myriad of factors. Initially, they delve into the cell’s potential capacity by analyzing the dynamics of the system, such as frequency response, and the highest values of force and extraneous loads, while also evaluating the impact of integrating the transducer within the force pathway. Mounting considerations include whether the load cell will directly or indirectly intercept the primary load, as well as the environmental conditions—like exposure to water or corrosive materials—and the spatial constraints where the load cell operates.

  1. Always leave sensor covers in place and intact.
  2. Ensure a stable power supply to prevent voltage surges.
  3. Handle load cell cables with care: avoid yanking, pinching, kinking, or bending them excessively.
  4. Monitor the environmental temperature around your load cell, ensuring it stays within the specified tolerance range.


When buying a load cell, ensure it meets various safety and performance standards, such as ISO, SAE AS9102, and ANSI/J-STD-001B. Additionally, it’s advisable to verify that the load cell has undergone insulation resistance testing.

The specific requirements can differ depending on your region and industry. For example, load cells intended for NASA need to meet NASA certification standards (NASA-STD-8739.3), while those used in the European Union must adhere to RoHS certification standards.

Things to Consider

Before choosing or installing a load cell for your application, it’s essential to evaluate several factors, including load cell capacity and positioning. To determine the load cell capacity, consider the maximum force value, the system’s dynamics (such as frequency response), the load cell’s reaction to the placement of a transducer in the force path, and the additional weight the load cell can handle. Load cells can contain between four and 30 gauges, and a higher number of gauges enhances the cell’s sensitivity in detecting and recording variations.

When installing the load cell, consider whether it will be positioned in the primary load path or used for remote force measurement. Evaluate any necessary physical modifications for size and mounting, the required level of accuracy, and potential environmental factors that could affect its performance. Careful consideration of these aspects ensures accurate readings and proper placement, enhancing safety in the factory, lab, and beyond.
