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.

We are very happy with the recent purchase of S-beam load cell and handheld load cell indicator. The ease of which to order exactly what we needed, and the expertise shown by your staff made the whole experience event free. Delivery time was very good and when received load cell and indicator, installation was quick and simple unlike the last item we received from another supplier. We will definitely be using Applied Measurements for any further purchases if required.

We chose Applied Measurements’ DBBSM s-beam load cells as the pigment is £1000 per tonne so has to be extremely accurate.

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.

Rod End Bearings for Tension Use

  • 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.
  • Zinc plated for corrosion resistance.
  • Are maintenance-free (in bearings with Elgoglide®, lubricant leads to a considerable reduction in bearing life)
  • Fitted with radial spherical plain bearings GE..UK or GE..UK-2RS
  • Hard chromium/PTFE composite or hard chromium/Elgoglide® sliding contact surfaces.
  • Enables compact adjacent construction thanks to its thin walled design of the eye housing.

Case Studies

S-Beam Load Cells in Yellow Pigment Dispensing Machine

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.

Equine Tension Load Cell

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.
