Abstract

High-accuracy mass measurements may be influenced by a number of factors, incl level of vibration. We have developed vibration monitoring system capable of measuring low vibration levels in the Estonian National Mass Standard Laboratory. The measurement system consists of three accelerometers attached to the massive base block in three perpendicular axes. The capabilities of our vibration monitoring system are limited to the range of frequency from 1 Hz to 100 Hz and acceleration from 1 mm/s² to 5 m/s². The first results show that vibration in this frequency range may influence the performance of our high-accuracy mass comparator.
