MARIETTA, GA – 09/2013 -

The Type 8921B01 portable shaker is a small, self-contained, battery powered vibration exciter specifically designed to verify/calibrate the sensitivity of accelerometers in a field environment.

• Test measurement system integrity

• Convenient, self-contained and portable

• Rechargeable battery for laboratory and field use

• Automatic shut-off

• Tests sensors up to 21 oz of weight • Conforms to CE

• Traceable to national standard

Description
The Type 8921B01 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 exceed 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 five hours between recharging.

Operator convenience and measurement confidence are of primary importance. The unit is portable, weighing 2.2 kg. 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 Type 8921B01 has sufficient force to test every sensor from the smallest laboratory accelerometer to large industrial sensors.

Application
The Type 8921B01 reference shaker can be used to confirm the sensitivity of acceleration, velocity and displacement sensors. Additionally, it provides convenient and accurate means of testing the integrity of the vibration measurement system from end-to-end. The unit is rugged and meant to withstand factory environments while providing years of reliable operation in the laboratory.
