    Applied Measurements DBBSUB submersible S-Beam load cell is ideal for tension and compression measurement in situations involving permanent submersion in water. They are hermetically sealed to IP68 to a depth of 10m/1bar making them ideal for flood susceptible locations, submersible and hydrostatic applications.

    The permanently submersible s-beam load cell has a dual bending beam design to ensure inherently high accuracy and enables us to guarantee performance well within specification.

    Our DBBSUB permanently submersible load cell can be supplied with specialised rod end bearings further guaranteeing the transducer’s optimum performance. For fast and simple installation they can be supplied with custom designed mounting plates and fixtures.

    If you require an IP67 rated S-Beam load cells with capacities of less than 50kg or greater than 10,000kg, our 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, Applied Measurements 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.
