1 oad cell Overview Combined error comb Repeatability v ±0.0% C n ±0.0% C n The shear beam load cell is particularly suitable for implementation in container, overhead rail conveyor and platform scales. esign The measuring element is a shear tension spring made of stainless steel to which strain gauges are applied. The strain gauges are arranged at 4 to the longitudinal axis on the side of the spring body and are therefore subject to shear forces. Under the influence of the load acting in the measuring direction, the spring bodies and therefore the friction-locked strain gauges are elastically deformed. This generates a measuring signal voltage that is proportional to the load.

5 ase plate with elastomer bearing Overview esign lastomer bearings are rubber-metal composites made of neoprene and stainless steel. Their special design means that lateral movement of the load bearing implement does not result in high transverse force on the load cell. If the load bearing implement is displaced by more than 4 mm (0.16 inch) in the horizontal direction, measures for restricting sideways play (e.g. stops) must be provided in the construction of the load bearing implement. The base plate of stainless steel is used for suitable fixing of the load cell on the base. The load cell is not included in the scope of delivery of the base plate or elastomer bearing. The base plate and the elastomer bearing form a self-centering bearing unit together with the load cells of the series. It suppresses oscillations and shocks to a certain extent.
