Portable reference shaker

The compact shaker provides an accurate, controlled vibration level to verify the sensitivity of vibration sensors or a complete measuring system. The internal control and excitation system provides a series of seven precise, selectable frequencies, while a closed-loop control maintains the selected amplitude independent of the mass of the test article.

Front panel indicators show the selected frequency and amplitude and battery condition. Should the test article exceed the capacity of the shaker, the unit provides an audible and visual warning to the operator.
