Portable vibration Calibrator

AT2040 Portable Vibration Calibrator

Three test methods to choose from


Mode one is a "shake" operation in which the PVC operates as a simple shaker table. This is useful for performing end-to-end checks or other vibration testing where accelerometer sensitivity is not needed.

The third main method of operation is "simulate" mode. Simulator mode is similar to "shake" mode, but a function generator is used instead of the electrodynamic shaker. The advantages of using simulator mode to perform vibration checks are numerous. The simulator is more accurate and performs over a wider range because it is not bound to the mechanical limitations of the electrodynamic shaker.

Sensor Sensitivity Test

The second mode to select from is "test" mode which displays the accelerometer or proximity probe sensitivity reading. These readings can be done in manual mode or full automatic mode. When performing sensitivity test in full automatic mode, a PDF calibration certificate is also generated by the AT-2040 portable vibration calibrator.

In manual mode, amplitude and frequency can be changed manually to show sensor sensitivity at the desired singular point.

Full automatic mode runs through a series of pre-defined calibration points and automatically shows the results in table format.

LiFeP04 Battery

The LiFeP04 battery outperforms Lead-Acid in almost every measurable way.

  • Longer Life Span of (5-10) years vs lead acid (3-5) years.
  • More cycle lifes - LiFeP04 batteries last 1,000 to 3,000 charge and discharge cycles compared to lead acid 200-1,000.
  • LifePo4 batteries are more environmental friendly than Lead Acid
  • Lighter weight. LiFeP04 battery cuts out 3lbs in AT2040 shaker vs lead acid.
  • Very Safe to use and does not need a dangerous good exemption for air transport like Lead-Acid Batteries.
  • Significantly faster charging time vs lead-acid batteries .
