Bilateral key comparison on calibration of accelerometers at low frequencies
Project Description
The specific task of this bilateral key comparison is the measurement of the magnitude of the complex charge sensitivity of two accelerometers in the frequency range from 0.2 Hz to 40 Hz. TÜBİTAK UME is motivated to participate in this bilateral comparison in order to confirm technical competence and to get an evidence for CMCs at primary calibration of vibration transducers in the low frequency range.
The sensitivity of accelerometer shall be calculated as the ratio of the amplitude of the output of the accelerometer to the amplitude of the acceleration at its reference surface with primary means in accordance with ISO 16063-11:1999 “Methods for the calibration of vibration and shock transducers - Part 11: Primary vibration calibration by laser interferometry”.
