Realization and dissemination of linear acceleration unit at UME

2002    Sadikoglu, E; Bilgic, E; Karaboce, B

At Turkish National Metrology Institute (UME), linear acceleration unit has been realized based on laser interferometry with different signal processing techniques. Absolute calibrations of reference accelerometers are performed by using fringe-counting and minimum point method in the frequency range from 20 to 10000 Hz. Dissemination of the linear acceleration unit to the secondary levels is carried out through a comparison calibration of vibration pick-ups by "back-to-back" method. Traceability chain for calibrations of the vibration calibrations and measurements performed at UME has been described in this paper.
