Description
Applied Measurements DBBSM universal load cell is suitable for tension or compression. It lends itself to a wide force and load measurement applications such as those found on tensile testing machines, suspended hoppers and geotechnical test equipment, as well as a wide range of other general purpose applications.
Our s-beam load cells are available to buy online from our webshop, with the 0-5000kg ranges in stock.
Our universal load cell features a dual bending beam sensing design on all capacities up to 1000kg, while a shear web sensing design is used from 2500kg upwards. Both designs offer excellent accuracy and are guaranteed to meet a specification of ±0.03% of the rated capacity of better.
Applied Measurements rod-end bearings and load buttons are available (see gallery images) to suit all universal load cell capacities and provide optimal loading conditions to ensure that you get the best possible performance from your measuring system. Plus, our expert knowledgeable team can customise the DBBSM s-beam load cell to suit your specific application.
If you need to fit into a restricted space, our DBBSMM range of miniature S-Beam load cells will fit the bill.

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.
Mounting and Installation Accessories
Load Buttons and Rod End Bearings
Designed to align forces through the principle axis of the load cell thus reducing the effects of extraneous forces, hence offering improved performance from the cell.
Load buttons are used where compressive forces are applied.
Rod End Bearings are used where tensile forces are being applied.

Case Studies
S-Beam Load Cells Promise Accurate Pigment Dispensing
We chose Applied Measurements’ DBBSM s-beam load cells as the pigment is £1000 per tonne so has to be extremely accurate” says Paul Akers, Works Manager at PD Edenhall Ltd. One of the largest independent concrete facing brick manufacturer in the UK, needed a way to accurately monitor the amount of pigment being dispensed into the weigh hopper throughout the manufacture of concrete facing bricks. The pigment amount needs to be precise as inaccurate amounts of pigment can lead to incorrect colour blends leading to a loss in sales and profit. Read how our accurate DBBSM s-beam load cells and intuitive4-L digital indicators were used in this construction industry application.
Complete Tensile Monitoring System Delivered in Under 1 Week
With huge capacities of up to 30,000kg and an accuracy of <±0.03% of the rated capacity, the highly accurate DBBSM S-beam load cell really is the knight in stainless steel armour. Not only can it efficiently handle the larger loads in the guys, it can also be supplied in less than 1 week! Its tough construction makes it ideal to use in the harsh outdoor conditions on the guy cables.
Force Measurement Determines The Effect of Girth Tension on Horse Gait
Using electrical systems for the measurement of mechanical forces is by no means limited to machines and laboratory based applications. In her recently completed research thesis ‘Girth Tensions and their Effects on Equine Stride Characteristics’, Sue Wright of Moulton College Northampton used load cells, motion sensors and GPS amongst other technologies to measure and record the tension within the girth strap used to hold the saddle in place.
