Accelerometer Calibration

VR’s accelerometer calibration performs automatic and accurate calibration and verification of IEPE accelerometers and charge mode piezoelectric accelerometers/transducers in your lab. The module provides an easy interface to calculate accelerometer sensitivity. The user can perform a sine sweep controlled on a reference accelerometer to produce a calibration report while calculating the accelerometer sensitivity at the defined frequency.

QUICKLY CALIBRATE

Calibrate a vibration accelerometer accurately to determine its sensitivity at various frequencies of interest. VR uses the most convenient and least expensive technique (per ISO 16063-21): the back-to-back comparison method, approved by the International Society of Automation (ISA).

Easy Procedure

  • Back-to-back reference sensor
  • Reads and re-writes to TEDS sensors
  • Compare sensitivities and save new values
  • Test Profile Included

Why calibrate?

  • Early detection of incorrect sensor sensitivity
  • Discover sensor defects
  • Higher level of confidence
  • Trust in your test results

Custom Reporting

Use the standard report template or customize your report using Microsoft Word. VR offers one of the most flexible custom reporting packages anywhere.

Save Time

VR knows your time is valuable. Our accelerometer calibration package eliminates the need to pack up each accelerometer for shipment back to the lab to be calibrated. Our package will reduce your downtime.

Save Money

The VR calibration package can be used on all your accelerometers for one price, time and time again. Simply hook up each unit for calibration, run the 10-minute verification procedure, retrieve the report, and continue on with your day.
