    Applied Measurements STALC3 submersible load cell is designed for use in fully submerged in water, at pressures up to 7000kPa.  Primarily they are used in triaxial chambers and can be retrofitted into existing triaxial chambers or installed into new ones.  Triaxial chambers are pressurised chambers used for testing the shear strength of core samples taken from the earth.  These provide a direct measurement of the axial compression load applied to the sample under test.  Read more about triaxial chambers on our triaxial testing page.

    In addition, our STALC3 submersible load cell can be adapted for use in other applications where they will be submerged in fluids including water and oil.

    Thanks to its pressure compensating system, incorporated within its design, there is no change in zero or sensitivity when the STALC3 load cell is subjected to external pressure changes.  Plus, the STALC3 also features accurate temperature compensation, excellent accuracy and stability, which is essential for the type of long term testing applications in which they are used.

    The standard 75mm diameter STALC3 submersible load cell is available in ranges from 0-1kN to 0-100kN.  The STALC3 can also be used to measure tension if required; for rated capacities up to 5kN tension loads up to the cell’s rated capacity can be applied.  For higher capacities of 10kN and upwards, tension rating is limited to 5kN as standard, however if you need to measure higher tensile forces we can manufacture customised versions on request.
