TEST OF IMPACT OF VIBRATIONS FREQUENCY ON MEAN ERRORS OF THE PRECISE HEIGHT DIFFERENCES MEASUREMENT WITH ANALOGUE AUTOMATIC LEVELLER NI002
Journal Title: Civil and Environmental Engineering Reports - Year 2018, Vol 4, Issue 28
Abstract
The article describes the results of tests carried out to determine the measurable effect of vibrations on the accuracy of measurements with an automatic precise leveller. It contains specification of the research station created to examine the case and description of factors affecting the measurement results. The multi-frequency vibrations were forced on a leveller during measurements and calculated mean errors for each frequency analysed. The range of frequencies for which the measurement was possible was estimated. The obtained results can be helpful in the engineering measurements designing, especially in industrial areas, where vibrations are an inseparable element of the environment.<br/><br/>
