The Moment Balance, also known as a Beam Balance or Single Piece Balance, is manufactured from a single piece of material with separate sections to measure each of the forces and moments (5 moments and 1 force). Moment balances can be very accurate with load capacities can be high; however, the moment balance has larger deflections when compared to a Hybrid Force Balance. The moment balance has a low dynamic frequency and the ability to absorb large dynamic loads. Smaller diameters are possible and costs are reduced. The model or test article is attached to the forward (metric) section with either a taper or other style interface, while the aft (non-metric) end is attached to the sting or ground side of the support system. Optional model / balance attachments are feasible.
The size of this balance can range from 0.30” to 3.0” diameter; maximum normal force ranges from 2.0 lb to 6,000 lb.
