HM8 Single-Shear-Beam Load Cell, 1-30 t Capacity (CAT#: STEM-BC-3370-ZJF)

The HM8 is a single-shear-beam load cell for medium- and high-capacity industrial weighing. It is manufactured from nickel-plated alloy steel. Fully welded sealing protects the sensing components from oil, water, and common corrosive media. The protection rating is IP68. Available rated capacities range from 1 t to 30 t. The load cell provides C3 accuracy with 3000 verification divisions. Optional ATEX classifications support selected explosive-atmosphere installations. It is suitable for platform scales, weighing modules, hopper scales, and truck scales.
