LabWorks LW139.141-75 Vibration System
The LabWorks LW139.141-75 Vibration System is a powerful linear amplifier permanent magnet field shaker capable of delivering up to 75 lbs of force over a frequency range of 0 - 6500Hz. LabWorks LW139.141-75 shakers feature a 3-inch diameter armature table and are ideal for larger loads which require high vibration levels. The shaker's full 1-inch armature stroke capability is ideal for many modal as well as low frequency general applications. The air cooled PA-141 linear amplifier is direct coupled to the shaker to give the maximum performance at low and high frequencies and can be easily switched from voltage source mode for general testing to current source mode for modal testing applications. Dual meters display the system operating levels and complete shaker and user interlocks help protect the system from accidental abuse. A guided flexure table base system is available for larger or heavier loads and loads with a higher center of gravity.
