These compact instruments are ideal for very small items (e.g., bullets) and record CG to +/-0.002′. The SE199 and SE300 models are designed to measure weight and precisely locate the CG of very small test objects along a single axis (dual-axis versions of these instruments are also available). They are particularly well suited for locating the axial position of the center of gravity of bullets and other small projectiles. The CG of a typical small-caliber bullet can be determined within +/- .002 inches.
The pair of microbalance models are simple to set up and operate for gathering weight and CG data from many payload tests in succession. With the help of our active moment transducers, moment sensitivity up to 0.01 g-mm is obtainable — a degree that far outperforms other instruments of this type. With proper fixturing, the CG of hard drive heads, gyro rotors, small turbine buckets, and other small objects can also be accurately determined. These instruments use the active moment transducer concept developed to achieve a sensitivity that is 100 times greater than usually possible with an instrument of this type.
