Weigh Bar® vs. Shear Beam

The Weigh Bar by design deflects more than a shear beam. This allows the Weigh Bar to absorb much more energy from shock loading. This ability to absorb shock loading is especially important in mobile applications where the equipment is used on rough and uneven terrain. The shear beams' inability to absorb energy often leads to using a cell rated at twice the capacity to compensate for this shortcoming.

Weigh Bars
Shear Beams
Design Purpose Specifically designed for farm use Usually a more generalised design for a variety of industrial applications
Accuracy Individual weigh bar .25% max error and system with multiple weigh bars 1% max error Variable depending on suitability of application but of generally lower system accuracy than weigh-bar design
Strength Based on inherently strong design with significant overload capacity Requires higher capacity due to their generally poor ability to withstand shock and side load
