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.

	Avery Weigh-Tronix 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
