  LS Series Vibration Test System
     
  The Long Stroke Series vibration testing systems are designed for
long stroke displacement test requirements normally performed by
hydraulic shakers. Compared to a hydraulic shaker where maximum test
frequency is typically around 400Hz. The Long Stroke Series is
capable to testing up to 3,000 Hz with a maximum of 100 g (bare
table) bounded by 2m/s maximum velocity. This provides users time
and cost saving for wide test requirements. These shakers are
suitable for test application such as package testing and vehicle
testing.
