ACR Compression Load Cell

Loadcell ACR

The ACR series load cells are designed for measuring compressive loads up to 10 tonnes are particularly suited for industrial application where optimum precision is needed. Featuring high-alloy tool steel construction for excellent repeatability, the unique element design provides high rated output (3 mV/V) with low deflection. It is recommended that the load cell should incorporate the flat, solid, machined bearing plate and mounting plate to provide the highest accuracy.

  • Hermetically sealed
  • Robust high capacity design
  • High rated output (3mV/V.
