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.
• Test measurement system integrity
• Convenient, self-contained and portable
• Rechargeable battery
• Tests sensors up to 300 grams of weight
• Conforming to CE
