2500 lbf. Vibration Systems
The series of Derritron “High Performance Air Cooled” shakers are
designed for a wide variety of dynamic test conditions including
Sinewave, Random, Shock and Seismic simulations over a wide
frequency range. We offer a complete turnkey solution for all of
your testing needs by supplying complete Shaker, Amplifier and
Controller packages at reasonable prices. These systems are
indispensable for complete and thorough product testing.
Derritron shakers are designed to run for extended periods over a
long life span. These rugged shakers offer high transverse vibration
strength and high axial stiffness and can be operated in either vertical
or horizontal mode. A built-in Automatic Load Support System
allows the armature to remain stable even with high test loads. A high
power blower insures proper cooling of the shaker and is included.
The standard Swivel Trunnion includes air isolation mounts to reduce the vibrations of the shaker from
transmitting to the floor. These shakers offer a variety armature head sizes to fully accommodate your test
requirements and will allow you to verify and improve the quality of your products.
