8921B

These small, portable, battery-powered vibration exciters are specifically designed to verify and calibrate the sensitivity of accelerometers out in the field.
Main features / advantages
  • Measurement system integrity check
  • Convenient, self-contained and portable accelerometer calibrators
  • Rechargeable battery for laboratory and field use
  • Automatic shut-off
  • Tests sensors up to 600 g (1.3 lbs) in weight
  • Traceable to national standard
These shakers of Type 8921B provide an accurate, controlled vibration level to verify the sensitivity of acceleration sensors or the complete measuring system. The internal control and excitation system provides a constant (Type 8921B01) or selectable (Type 8921B02) precise frequency, while a closed-loop control maintains a constant (Type 8921B01) or selectable (Type 8921B02) amplitude independent of the mass of the test article. Should the test article exceed the capacity of the shaker, the acceleration calibrator 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.
