Silicon Audio Seismic

Digital Sensor System

SHARE

To capture the full performance of our optical interferometer-based seismometer we developed a complete digital sensor system. High levels of integration allow for a compact, low mass and highperformance sensor installation that can act as the heart of geophysical monitoring stations.

With the largest dynamic range available among seismic sensors, the Silicon Audio sensor eliminates the need for multiple sensors to maximize the signal capture in terms of seismic amplitude and bandwidth. For example, applications which once required a broad-band seismometer paired with a strong-motion accelerometer can be addressed with a single Silicon Audio digital sensor
