Measuring what we can’t feel – seismic sensing

For safety-critical infrastructure such as power plants, bridges, tunnels and dams, reliable seismic monitoring is vital. In areas exposed to tectonic activity, structures need to be monitored continuously – not only to detect potentially dangerous seismic events, but also to understand the long-term effects of micro-movements on structural integrity.

The challenge lies in capturing extremely small vibration amplitudes.

This is where capacitive accelerometers from the ASC EQ series excel. With a resolution of less than 1 µg and compliance with Motion Class B requirements, they provide the sensitivity needed to reliably measure even lowest-amplitude seismic vibrations.

Accurate seismic data helps engineers assess how structures respond to ground motion, identify changes that may indicate earthquake-related fatigue and make informed decisions about inspections, maintenance and structural health. In critical situations, rapid detection can also support timely alerts and appropriate safety measures.

As for sensitive buildings and critical infrastructure, detecting the tiniest movements can help prevent major consequences.
