principle of vibration welding

Load Cell Technology

The ring torsion measuring principle is relatively new, and ideally suited for the capacity ranges which are typically served by shear and bending beams. VPG Transducers load cell model RLC is a low profile, stain- less steel ring torsion load cell, based on a full bridge circuit of four circular strain gages.
