Abstract

Accelerometer comparison calibration technique involves the back-to-back coupling the accelerometer under test directly to a traceable reference standard accelerometer and both accelerometers will be experienced the same motion from shaker. Thus the sensitivity of standard accelerometer can be transferred to the test accelerometer via a calibration constant from the output signals. The results of the relative expand uncertainty for the voltage sensitivities for accelerometer are less than 1.4 %, 1.9 % and 2.9 % within frequency range from 50 Hz to 1.5 kHz, from 1.5 kHz to 5 kHz, and from 5 kHz to 7 kHz, respectively. This paper will present the construction, the performance evaluation of the calibration system in NML, CMS/ITRI.
