What is an S-Beam Load Cell?

An s-beam load cell is a sensor shaped like an ‘S’ which measures both tension and compression.

How Does an S-Beam Load Cell Work?

As tension is applied to the sensor the central beam of the s shape acts like a spring and compresses or stretches depending on the direction of the force.  For example, if a compression force is applied, the central beam will compress and if tension is applied the central beam will stretch.

Strain gauges are attached to the central beam which converts the deformation into an electrical signal.

How to Install an S-Beam Load Cell

Our Applied Measurements experts have put together a 5-step guide to demonstrate how to correctly install an S-beam load cell.

Step 1 – Keep the Forces Centrally Aligned

To reduce any off-axis loading, forces must be centrally aligned through the centre of the load cell.  We can supply optional load buttons and rod ends which work to reduce any side loading.

Step 2 – Do Not Overtighten the Rod Ends and Load Buttons

When using rod ends and load buttons be sure not to overtighten them when attaching them to the S-beam load cell.  As this can cause damage to the load cell.

Step 3 – Always Leave a Gap

Ensure that the rod ends and load buttons do not touch the central beam.  If a gap is not maintained, the central beam will not be able to move freely when tension or compressive force is applied.

Step 4 – Mount on a Flat Surface

Always secure the S-beam load cell to a clean, flat surface of better than 0.005mm surface flatness.

Step 5 – Contact with Active Area Only

When installing the S-beam load cell ensure the load is applied to the active end area only.
