TECHNICAL INFORMATION

EARTH MOTION FROM ALL DIRECTIONS

Stay on scale with the RS4D! Incorporating both a vertical velocity geophone sensor and three orthogonally positioned microelectromechanical systems (MEMS) accelerometers, the RS4D is an incredibly versatile seismograph.  It is capable of measuring both strong motion and micro-seismic activity. 

This highly portable, turnkey device integrates the velocity and acceleration sensors, digitizer, hyper-damper, and computer into a single unit. The addition of the MEMS sensors effectively widens the decibel measurement band of this seismograph, to ensure it remains on scale during large earthquakes, which it measures across all axes. The combination of sensors also extends the device’s use cases, allowing it to be used in applications where an accelerometer is required, such as for structural health monitoring. 

The RS4D is the complete package. Monitor the vertical motion of local and global seismic activity from all magnitudes of earthquakes, and remain on scale to measure larger more powerful local earthquakes across the east, north, and vertical axes (triaxial).
