BALANCE MACHINES

True static CG measurement eliminates errors due to air turbulence on irregularly shaped objects such as satellites Slow spin speed minimizes centrifugal forces on payload Two plane concept allows simultaneous measurement of CG offset and product of inertia No hydraulic pump; no danger of explosion due to mist from high pressure oil line; no risk of contamination of specimen or cleanroom facility With the Space Electronics POI series Spin Balance Machines, only one machine is needed to make mass properties measurements. Our unique gas bearing design allows measurement of dynamic unbalance, product of inertia (POI), center of gravity (CG), and moment of inertia (MOI) with a single setup on a single machine. By eliminating the need for multiple machines, the time required to make these measurements is greatly reduced. Alignment errors that occur during setup on different machines are eliminated. In addition, since the test object is not moved between measurements, the potential for handling damage is minimized.
