Miniature S-Beam Load Cell | Z-Beam Force Sensor | DBBSMM


Applied Measurements DBBSMM miniature S-Beam load cell (or Z-Beam load cell) is suitable for use in tension and compression and lends itself to both force and load measurement applications where the space to mount a standard size load cell is not available.

All of our miniature S-Beam load cells offer high accuracy of better than ±0.03% of their rated capacity and can be optionally gel-filled to provide a waterproof device suitable for applications such as wave tank monitoring.

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

If you require a miniature S-Beam load cell with a capacity greater than 50kg, Applied Measurements can manufacture special versions of the DBBSMM with measuring ranges of 100kg, 150kg, 200kg and upwards on request.  Please contact your Applied Measurements expert sales team using the form in the sidebar to discuss your miniature s-beam load cell requirement in detail.
