UTILCELL / DB903A SERIES DOUBLE-ENDED SHEAR BEAM LOAD CELL


Product description:

DB903A is a double ended shear beam, both ends loaded, center supported via self-aligning ring groove structure, so that the force can be applied properly. This load cell is suitable for a wide range of truck scales, rail scales and process weighing equipment of tank, bin and hopper scale, etc. It is bolted at both ends.. Fully alloy steel construct, hermetically sealed, which ensure high seals performance of waterproof.

Main Features:

• Material: Alloy steel

• Rated Capacities: 10klb~250klb

• IP Rating: IP68

• Suitable for truck scale, heavy duty hopper scale and other electronic weighing devices.

• High precision by NTEP III L 10000, high reliability.
