MP Weight/CG/MOI Series

Mass Properties Made Easy: Our MP series of instruments measure in one setup the weight of the payload, two coordinates of the center of gravity location, and one moment of inertia.

Portability: Our MP instruments are self-contained instruments that are easy to transport and easy to set up. They are particularly well suited to field measurements.

Speed of measurement: As no rotation is required to make center of gravity measurement, the operator can measure weight, 2 coordinates of center of gravity and moment of inertia in about one minute.

Measurement concept:

– Weight and Center of Gravity: These instruments use the multi-point weighing method to simultaneously measure both weight and CG. Less than one minute is required to make a measurement, so these instruments are ideally suited to high volume production.

– Moment of Inertia: The instrument uses a flat gas thrust bearing to support the test part weight, a cylindrical bearing for precise centering, and a torsion rod as a rotational spring. To measure MOI, the test table is manually rotated through a small angle and held against a fixed stop. When released, the table will oscillate freely since the load is supported and centered by a nearly frictionless gas bearing. A digital timer determines the period of oscillation.

Automated Operation: A Windows based computer system is provided with the MP6500 system. The MP6500 operating software prompts the user through the testing sequence, acquires data, calculates results and generates a report.

Calibration hardware provided: Each MP instrument comes with calibration hardware certified to NIST.

Gas Supply: A source of pressurized nitrogen or dry clean air capable of delivering 2 CFM at 75 PSI must be provided for the operation of the gas bearing. For locations that do not have a permanent nitrogen line or oil-less dry airline, this gas can be supplied from a Space Electronics Instrument Air Supply. (Note: Shop air usually contains oil and water and is not acceptable.)
