    Applied Measurements DBB Z-beam load cell / S-beam load cell is suitable for use in tension or compression with IP67 immersion protection to 1m.  The design lends itself to both 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.

    The sensing principle employed on our Z-Beam load cell varies, with a dual bending beam design on the DBBE model which covers capacities from 50kg up to 1000kg and a shear web design on the DBBWAS model which cover ranges from 0-1500kg to 0-6000kg.  Both sensing principles offer inherently high accuracy and enable us to guarantee performance of better than ±0.03% of rated capacity.

    All our DBB models are constructed from nickel-plated alloy steel.

    Rod end bearings and load buttons are available (see gallery images) to provide optimum loading conditions.

    If you require a Z-Beam load cell with capacities of less than 50kg or greater than 6,000kg, Applied Measurements DBBSM series of S-Beam load cells covers load ranges from 0-1kg (10N) up to 0-30,000kg (300kN).  Meanwhile, 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.

    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.
