Description

Applied Measurements DBBSM universal load cell is suitable for use in tension or compression and 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 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 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 knowledgable 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 chose Applied Measurements’ DBBSM s-beam load cells as the pigment is £1000 per tonne so has to be extremely accurate.

Paul Akers, Works Manager, PD Edenhall Ltd, 31/May/2018, Universal Load Cell | Universal S-Beam Force Sensor | DBBSM June 1, 2018

For our new larger mast range with large head loads we needed an instrument with a higher range up to 500kg and in a hurry, so that’s how we decided upon your product.

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.

  • 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.

    S-Beam Load Cells Promise Accurate Pigment Dispensing

    S-Beam Load Cells in Yellow Pigment Dispensing Machine

    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.

    Force Measurement Determines The Effect of Girth Tension on Horse Gait

    Equine Tension Load Cell

    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.
