DB940A SERIES DOUBLE-ENDED SHEAR BEAM LOAD CELL
Product description:
DB940A is a double ended shear beam, both ends loaded, center supported via self-aligning semicircular arc convex structure, so that the force can be applied properly. This load cell is suitable for a wide range of truck scales, giant vessel scales and rail scales. It is designed to be lifted via a pair of parallel connected ring at both ends. Fully alloy steel construct, hermetically sealed, which ensure high seals performance of waterproof.
Main Features:
• Material: Alloy steel
• Rated Capacities: 25klb~100klb
• OIML NTEP HB44, CE and RoHS certified
• IP Rating: IP68
• Suitable for truck scale, heavy duty hopper scales and other electronic weighing devices.
• High precision by NTEP III L 10000, high reliability.
