Three-component seismometer SPV-3K is designed to convert velocities acting along measurement axes of seismometer into proportional electrical signals. The seismometer is intended for work with seismic recording system Delta-03 or any other recording system.
APPLICATIONS
•measurement of amplitudes, natural and forced vibration periods of buildings, structures and critical facilities for the purpose of evaluating their seismic resistance
•detailed seismic zoning and seismic micro‐zoning
•seismology
•seismic exploration.
The Seismometer can come equipped with a system which records its deviation from a vertical axis with the display of vertical deviation angle or generation of alarm signal in the case of excessive deviation (optional). This information can be used to determine the position of a Seismometer in offshore seismic exploration conditions.
