The LW127.141-225 system utilizes the ET-127 shaker in a lower force output system. Suitable for larger loads that don't require high vibration levels, the 225 system offers the benefits of the larger shaker at a reduced price 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. Oil film slip table base systems are available for larger and heavier loads or loads with high centers of gravity.
