Configure VibrationVIEW to Calibrate Piezoelectric Accelerometers

January 2, 2019

Equipment Needed

    • VR9500 vibration controller
    • PC with VibrationVIEW Sine software and the accelerometer calibration add-on package
    • VR5200HF shaker and amplifier
    • Reference device (REF): For example, a Dytran 3027B back-to-back accelerometer
    • The device under test (DUT): The piezoelectric accelerometer to be calibrated
    • Cables

Set-Up

1. Connect and power the PC, controller, shaker, and amplifier

2. Mount the DUT accelerometer to the REF in a back-to-back configuration

Make sure to use a good mounting technique (see blog post:  Accelerometer Mounting Tip Sheet.)

  • Stud mount the REF to the shaker head
  • Stud mount the DUT to the top of the REF

3. Make testing connections

  • Connect the REF to Input Ch1
  • Connect the DUT to Input Ch2

4. Configure VibrationVIEW

  • Click Configuration > System Limits; select Vibration Research VR5200
  • Click the Inputs tab
    • Select accelerometer power for Ch 1 and Ch 2
    • Enter the proper Sensitivity for Ch 1 and Ch 2
    • If the DUT supports TEDS, check the TEDS box

    • Click OK

5. Create the calibration test profile for Ch2

  • Click the Navigator button
  • Click the Sine library > Sine Accelerometer Calibration

Sine accelerometer calibration in VibrationVIEW

    • Click OK
    • Enter a file name for the Sine test profile

6. Run the Test

  • Click the Run button

  • Fill in the test information on the HTML form

  • Click Continue. The calibration of the DUT accelerometer will run at 100Hz. After the calibration is complete, the test will verify the accuracy across a full operating range of frequencies.

7. After the Test Completes

  • Click Save New Values and VibrationVIEW will update the TEDS information stored on the DUT accelerometer

  • VibrationVIEW will generate an Accelerometer Calibration report as an Excel file
