Specification

The Type 8921 provides an accurate controlled vibration level to verify the sensitivity of vibration sensors or the complete measuring system. The internal control and excitation system provides a constant, exact frequency while a closed loop control maintains a constant amplitude independent of the mass of the test article. Should the test article exceeds the capacity of the shaker, the unit provides an audible and visual warning to the operator. A self contained, rechargeable battery can power the shaker up to approximately these hours between recharing.
