Accelerometer Sensitivity (24110C)

NIST calibrations of accelerometers are performed by absolute measurements, following ISO 16063-11. A calibration consists of measuring the sensitivity of the accelerometer at customer-selected frequencies from the standardized one-third-octave frequency series within the range of interest. An alternate set of
standardized frequencies and/or a limited number of additional frequencies within the range of 10 Hz to 20,000 Hz may be included in the 24110C service at the customer’s request; please contact vibration@nist.gov for additional information.

The sensitivity of an accelerometer is the ratio of the electrical output to an applied level of acceleration. The electrical output of an accelerometer is either charge or voltage, thus the sensitivity is expressed in either mV/(ms-2) or pC/(ms-2).

All measurements are performed at 23 ± 2 °C. The calibration is reported as the sensitivity at a set of one or more discrete, customer-chosen frequencies.

The calibrations have a typical relative expanded uncertainty of 0.3% to 2.0%, depending on the frequency range.

Accelerometer Special Test (24130S)

NIST Special Tests of accelerometers are performed by absolute measurements, following ISO 16063-11. All measurements are performed at customer-selected frequencies. Accelerometer Special Test 24130S permits calibrations of accelerometers at a wider frequency range than 24110C; in particular, accelerometers can be calibrated at frequencies as low as 0.2 Hz; accelerometers may also be measured at frequencies as high as 50 kHz. Accelerometer Special Test 24130S also permits calibrations of accelerometers with unique configurations. Please contact vibration@nist.gov to discuss your specific requirements.
