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.
Operator convenience and measurement confidence are of primary importance.
the unit is portable, weighing 4.5 pounds. Front panel indicators provide information as to the condition of the internal
battery. An automatic shut-off circuit switches off the power automatically after 10 minutes of continuous operation. The 8921 has
sufficient force to test every sensor from the smallest laboratory accelerometer to the large industrial sensors.
