Z6 Bending Beam Load Cell: The Market Standard for Precision and Robustness in the Weighing Range from 5 kg to 1 t

The precise Z6 bending beam load cell, developed by HBM in 1972, has been continuously optimized for decades. Z6 is based on strain gauge technology. It is available in nine different versions with maximum capacities that range from 5 kg to 1 t. The load cell with the characteristic bellows has become a worldwide standard, with millions of load cells having been sold. It is employed in platform and conveyor scales for dosing and level measurement as well as in weighing modules that, for instance, are used for tank weighing applications. The metal bellows protect the load cell against the ingress of moisture. The Z6 load cell has been optimized for connection in parallel. An IECEx-ATEX-compliant explosion-proof version is also available.

  • Accuracy class (OIML): up to C6
  • Nominal load: from 5 kg to 1 t
  • Degree of protection: IP 68
