The Evolution of Shear Beam Load Cell

Introduction to Shear Beam Load Cell

Shear beam load cells have proven to be highly efficient and productive for sectors where goods are produced and processed. These load cells are suitable for medium or large-capacity weighing applications.

The possible applications of shear beam load cells include constructing multi-sensor scales, for weighing tanks, or for onboard weighing. These load cells consist of a piece of metal that deforms under the influence of force and returns to its original state when the force is removed.

Strain gauges register this deformation and convert it into an electrical signal. Shear beam load cells are calibrated in units of weight (grams, kilograms, or tons). They’re extremely useful to measure torque or force in industrial systems.

Shear beam load cells are built correspondingly robust due to their main use in the industrial sector. These load cells are immune to ingress of dust and strong splashing water or even submersion.

The shear beam load cell is designed for low profile scale and processing applications. With capacities from 100kg to 50t, they’re extremely precise and feature stainless steel construction for use in harsh environments.

The Advantages of Shear Beam Load Cell

Shear beam load cells are ideal for measuring switching or actuating forces. They’re firmly attached to the application/platform on one side of the beam and force is applied vertically.

The double bar measuring principle is important to measure this vertical force. However, the sensors of these forces are largely insensitive to the displacement of the vertical force introduction.

At CUBLiFT, we rely on advanced strain gauge technology, which leads to precisely defined relative changes in resistance of the strain gauges. The resistance of the strain gauges is visible to the introduction of the force on the measuring shear beam load cell.

Our advanced shear beam load cell manufacturing technology enables us to optimally suppress the temperature influences and lateral forces.

The Applications of Shear Beam Load Cell

The shear beam load cell is ideal for industrial weighing applications. Its primary use is in the following industrial weighing equipment:

• Belt scales
• Filling systems
• Container scales
• Checkweighers
• Platform scales in the middle range
• Big bag scales
• Floor scales
• Silo scales

Moreover, shear beam load cells are suitable for torque and force measurements. Shear beam load cells are sued in weighing technology to determine the weight of small-/medium-sized vessels and are also frequently used in force measurement.

The agricultural industry, for example; uses shear beam load cells for gravimetric level weighing.

Moreover, beyond the agricultural and industrial applications, shear beam load cells are produced in many other ways:

• Traditional weighing machine construction
• Crane scales, truck scales, and vessel scales
• Platform weighing through platform scales
• Weighing in-process and dosing systems

Furthermore, shear beam load cells are also often installed for applications in the building materials industry, the food industry, the chemical industry, and medical technology.

Shear Beam Load Cell: Indispensable in Weighing Technology

A finely calibrated shear beam load cell indirectly and precisely determines the weight force by measuring and converting the weight force into a path.

Working Principle of a Shear Beam Load Cell

A weight force can deform a shear beam load cell’s bending beam or a built-in spring.

Afterward, the intensity of this deformation gives information about the weight force or, more precisely, about the object weight.

Furthermore, with this information, you can precisely weigh any material that belongs to industrial applications.

The Core of Shear Beam Load Cells

In a shear beam load cell, a pair of special strain gauges attached/mounted in the measuring bodies plays an important part by acting as a mechanical intermediate stage in the measurement process.

In case the measurement body deforms, it’s transferred to the strain gauges to convert this elastic deformation into electrical signals.

With a measurement accuracy of 0.01%-0.05% F(nom), such changes in resistance can be easily and very accurately measured.

The advanced technology of shear beam load cells offers the following:

• Consistent high quality
• Exact measurement directly in the force flow
• Very good temperature characteristics
• High long-term stability

A laser is used to weld standardized sensors into the measuring element with shear beam load cells which enables automated series production.

Level Monitoring with Shear Beam Load Cells

Shear beam load cells are proven to be extremely productive in level monitoring processes. It can check fill levels by measuring the weight of the vessel and its contents.

The measuring data from this gravimetric level monitoring helps calculate the filling height of a vessel or a tank.

The following are some advantages of this measurement method:

• Measuring the level and the exact mass at the same time
• Eliminating the contact with the medium because of no access required to the tank or vessel
• Independent measurement of the material, its properties, and the geometry of the container
• If necessary, shear beam load cells can be easily replaced

In level measurement, shear beam load cells must function regardless of the nature and condition of the medium:

• Small or large grain sizes
• Liquid or solid
• Hot or cold
• Aggressive or mild
• Steaming or icy
• Conductive or non-conductive
• Foaming or dust

Regardless of the geometry of the vessel and its evenly or unevenly distributed medium, the load cells must also operate well.

Such factors must not affect the measuring result, performance, or any other permanent functions of a load cell.

The current condition also applies in applications that are temperature-critical where robustness and high durability are required.

These are some reasons why high-precision shear beam load cells are ideal for nearly every industrial environment and application.
