The LW140.141-110 is our strongest compact linear amplifer shaker system. Capable of up to 110 lbs. force, the 3-inch diameter armature table is suitable for larger loads that require high vibration levels. The shaker's full 1-inch armature stroke capability is ideal for many modal as well as low and high 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 lateral flexure table base system is available for larger and heavier loads or loads with a high center of gravity.
