PW28: Single Point load cell for dynamic weighing PW28: Single Point load cell for dynamic weighing | HBM

PW28 Single Point Load Cells for Precise Weighing of Masses from 5 kg to 75 kg

Owing to its ratio of minimum verification interval of up to 20,000, the PW28 single point load cell complies with the C3 multi-range, or, optionally, the even higher C4 MR accuracy class, providing extremely precise results. It is suitable for both static and dynamic applications due to its high stiffness. Stainless-steel housing and IP67 degree of protection permit reliable operation in industrial environments. All PW28 load cells, irrespective of their maximum capacity, feature integrated and encapsulated overload protection, ensuring stability against unexpected overload.

  • Accuracy class: C3 MR, C4 MR in compliance with OIML R60
  • Nominal (rated) measuring range: 5 kg to 75 kg


  • Accurate weighing up to C3 multi-range / C4 multi-range accuracy class (in compliance with OIML R60)
  • Precise results owing to the minimum verification interval ratio of up to 20,000
  • High bending and torsional stiffness
  • Off-center load compensation

Precise measurement results due to protected and premium strain gauge load cell technology


  • Stainless steel housing
  • Resistant to humidity and dirt in industrial environments, due to the IP67 degree of protection (in compliance with EN 60 529)
  • Integrated and encapsulated overload protection

Safe use in industrial environments owing to its high degree of protection and encapsulated overload protection


  • Six different maximum capacities are available (5 kg, 10 kg, 20 kg, 30 kg, 50 kg, and 75 kg)
  • The load cell is available as the standard version with a minimum verification interval ratio of up to 10,000 or, alternatively, as a version with 20,000
  • The robust M12 connector plug allows for variable connection of different cables

Versatile in use due to six selectable maximum capacities and the possibility to connect different cables
