Presentation of root-mean-square value (RMS) of vibration velocity and peak-topeak value of vibration displacement. The calibrator consists of a vibrostand, control unit including a kit of auxilliary equipment.

Area of application

Verification and calibration (vibration meters) of vibration displacement sensors (VDS) with eddy-current transducers and vibration velocity sensors during their operation and manufacture – the calibrator presents the required RMS of vibration velocity and peak-topeak value of vibration displacements of a vibrostand's (VS) table vibrations. For eddy-current VDS simulation of a reference surface with respect to which the peak-topeak value of vibration displacement is measured is implemented by removable disks made of different grades of steel.
