Space Electronics - Test Fixtures

Measurement accuracy is highly dependant on the fixture used to support your payload on the measuring instrument. Space Electronics offers its extensive experience in designing and manufacturing fixtures to suit a full range of test parts from hard-drive components weighing a few grams to space satellites weighing 10 tons.

Blade adapters for moment weight scales - Space Electronics "Gravity Wedge" blade adapters are more repeatable and easier to use than any other style of adapter. Tare moment is not altered by insertion of blade. Repeatability is better than 1 part in 100,000. Please visit our specific blade adapters page.

L-Adapters - Our KSR and POI series machines measure in one setup 2-axis CG and MOI about a single axis. In order to measure the other mass properties of an object, it is necessary to reposition it relative to the machine. Our L-adapter supports the object horizontally and includes a rotary table which allows you to turn the object about its axis to obtain two additional MOI measurements and the third CG measurement.

Roller Vees - Roller Vee fixtures are used to position cylindrical objects on a mass properties measurement instrument. It allows to measure CG in two axes and MOI in one axis, then rotate the payload by 90 degrees to measure the third CG coordinate and a second MOI.

Tilt / translation tables - These fixtures allow translation of the payload in two horizontal axes and rotation around the center of gravity of the payload. They are used to precisely adjust the verticality of the payload and the position of its center of gravity over the centerline of our KSR and POI Series of instruments.
