Accelerometer Calibration

Accelerometer calibration and is quick and easy with the AT-2030, AT-2035, and AT-2040 series shakers. If your operating in a environment with a large amount of sensors, it makes financial sense to do the calibrating yourself rather than sending your accelerometers to a lab or manufacturer. Accelerometer Calibration expenses can add up very quickly, with the average calibration cost being anywhere from $200-$700 per accelerometer yearly. By using a portable vibration calibrator, operators will find their machine downtime is greatly reduced and the process of mailing your sensors to and from the calibration lab can be eliminated.

Before You Begin

      1. Make sure that your portable vibration calibrator is fully charged. The Agate Technology Shakers feature an auto-shutdown feature to protect the battery to ensure long-term use of the equipment. Keeping the calibration shaker charged ensures that it will not unexpectedly power down during Accelerometer Calibration.
      2. Make sure your external meter is working correctly (AT-2030 Only). When using the AT-2030 a meter is required to read the measurements. It’s important that your meter be correctly calibrated and have working batteries. If using AT-2035 or AT-2040 skip this step; sensitivity and calibration readings are built in to the unit.





    1. Make sure you have the correct adapters. Agate calibrators each come with 6 mounting adapters, a mounting pad, and a mounting plate. This is is sufficient for most Accelerometer Calibration jobs, but make sure to check that you will not be needing a less common adapter or spacer.

Now You’re Ready to Begin Accelerometer Calibration

Follow these simple steps and you will have your accelerometer calibration completed in no time.

    1. Using the provided short hand accelerometer wrench, secure the reference accelerometer from movement. The shaker and reference accelerometer are connected by four carbon fiber flexures. Use the wrench to ensure that torque is not applied to these parts when tightening down your test accelerometer.






  1. Connect your cable from the accelerometer under test. If using the AT-2030 you will need to connect to an external source such as a multi-meter or vibration monitor control meter. If using AT-2035 or AT-2040, simply plug the test accelerometer to the BNC connector labeled “Sensor Input”

    Wilcoxon Research Velocity Transducer connected to sensor input for sensitivity reading.

  2. Set the portable vibration calibrator to the correct frequency and amplitude and begin your measurements. Using the manufacturer datasheet as a guide, set the correct frequency and amplitude and take your first reading. After that is complete, move on to your second, and so on. If using the AT-2035 or AT-2040 and your sensor is preset, the “Auto” button will perform an automatic sweep of all needed accelerometer calibration points for you and store the data.
  3. Create your certificate. If using the AT-2030 you will need to input your data into Excel and print your certificate manually. If using the AT-2035 or AT-2040, simply download your automatically created certificate to USB in PDF format.
  4. All Done!
