Sensors we calibrate
What we measure
| Parameter | What it checks | Method / standard | Typical |
|---|---|---|---|
| Reference sensitivity | Output per g (mV/g or pC/g) at reference frequency | Comparison to reference accelerometer at ~159.2 Hz, ISO 16063-21 | Reported value ± uncertainty (~1%) |
| Frequency response | Sensitivity deviation across the band | Sine sweep (e.g. 5 Hz-10 kHz) vs reference | % deviation vs reference |
| Amplitude linearity | Linearity over the amplitude range | Multiple levels at the reference frequency | Within spec (%) |
| Transverse sensitivity | Unwanted cross-axis output | Per ISO 16063 | Typically a few % max |
| System sensitivity | Whole-chain mV/g | Accelerometer + cable + conditioner + analyzer measured together | Reported with channel settings |
In-lab vs on-site calibration
In-lab calibration
- Accredited bench with full reference standards
- Best achievable measurement uncertainties
- Pickup & return logistics handled
- Ideal for precision and reference work
On-site calibration
- We calibrate the accelerometer at your facility
- No shipping risk or transit downtime
- As-found data captured before any move
- Ideal for fixed, large or sensitive assets
In-depth guide
Calibration for accelerometers and complete vibration measurement systems
Accelerometers are measuring devices used to detect and measure acceleration in physical objects or systems. We know that they are important in a variety of industrial applications because of their ability to provide crucial information about motion and vibration. Whatever the application of your accelerometers, such as vibration monitoring of engines, turbines, compressors, and pumps. We know that your periodic calibration will help early detection of abnormal vibrations that can cause failures, reduce downtime, and improve plant safety. Our Calibration Laboratory has extensive experience in the calibration of this type of instrument, both for individual accelerometers such as Triaxial, Piezoelectric, Piezoresistive and for complete vibration measurement systems including vibration controllers and monitors. We recommend an annual calibration for accelerometers and vibration measurement systems; it is important to have both in the calibration cycle to ensure the frequency and sensitivity are correctly rated.Calibration for accelerometers and vibration measurement systems keeps sensitivity, frequency response and phase traceable to national standards. Before choosing a Calibration Laboratory, you should evaluate several key factors: Accreditation, Experience, Metrological Traceability, Equipment, Procedures, and Customer Service.

Equipment: It is always important to know that the laboratory is professional and reliable. It will be important you know their facilities and verify that their equipment or calibration standards are modern and have maintenance processes for their standards.
