Applied Measurements DBBSMM miniature S-Beam load cell (or Z-Beam load cell) is suitable for use in tension and compression and lends itself to both force and load measurement applications where the space to mount a standard size load cell is not available.
All of our miniature S-Beam load cells offer high accuracy of better than ±0.03% of their rated capacity and can be optionally gel-filled to provide a waterproof device suitable for applications such as wave tank monitoring.
Rod end bearings and load buttons are available (see gallery images) to provide optimum loading conditions.
If you require a miniature S-Beam load cell with a capacity greater than 50kg, Applied Measurements can manufacture special versions of the DBBSMM with measuring ranges of 100kg, 150kg, 200kg and upwards on request. Please contact your Applied Measurements expert sales team using the form in the sidebar to discuss your miniature s-beam load cell requirement in detail.
If you are not space-restricted, our DBBSM series of load cells covers load ranges up to 0-30,000kg (300kN).

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.
Load Buttons for Compressive Use

Rod End Bearings for Tension Use
Maintenance-free rod ends are a complete units made up of a housing with both an integral shank (with an internal or external thread) and a maintenance-free spherical plain bearing, located within the housing.
- Supports radial loads in a tensile or compressive direction.
- Suitable for unilateral loads – can support alternating loads and alternating loads in combination with bearing GE..UK-2RS, consult sales.
- Zinc plated for corrosion resistance.
- Are maintenance-free.
- Fitted with radial spherical plain bearings GE..UK
- Hard chromium/PTFE composite sliding contact surfaces.
- Enables compact adjacent construction thanks to its thin walled design of the eye housing.

How to measure grip strength of an eagle for BBC Natural World
Last year, we were asked to design a sensor to measure the grip strength of a golden eagle named Tilly, for the award-winning BBC documentary series, Natural World.
Challenge - to find a load cell that could withstand the estimated grip strength of an eagle.
As Tilly had been trained to catch and grip a tennis ball, the load cell needed to be small enough to fit inside a similar-sized measuring device yet withstand Tilly's tremendous grip strength.
Thanks to their unique design, our DBBSMM miniature s-beam load cells were ideal for the job. Not only are they very compact but their s-shaped design offers superior side-load rejection and high accuracy.
Universal Fabric Tension Tester for All Fabrics and Styles
The Challenge - Accurately Measure Fabric Tension on Any Style of Furniture.
Fabric strength testing guarantees the fabric being used on furniture meets the high quality needed for durability, comfort and support.
Choosing the wrong type of fabric can lead to fabric tearing, loss of customer satisfaction and a decrease in sales and profit.
Find out how our miniature s-beam load cell, intuitive4-L digital indicator and industrial LVDT displacement sensors were used to determine fabric strength.
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.
