Reliable detection of ground motion
Even small ground movements can have major effects on buildings, bridges, and industrial installations. Continuous vibration or minor seismic activity can lead to cracks, fatigue, or misalignment over time.
Seismic sensors make these movements measurable. They record ground acceleration or vibration with high accuracy and enable early reaction to possible structural damage or process disturbance.
Technology behind modern seismic sensors
Our ASC, EQ series seismic sensors are based on MEMS (Micro-Electro-Mechanical Systems). These sensors use capacitive measurement technology and are designed for very low-frequency vibration detection.
Key performance details
- Measurement range: typically ±3 g or ±5 g
- Noise performance: up to ~113 dB signal-to-noise ratio (at ±3 g)
- Frequency range: optimized for low frequencies (0–20 Hz), extended up to 100 Hz
- Resolution: better than 1 µg (one-millionth of gravity)
This combination makes the sensors suitable for both structural health monitoring and earthquake early warning systems. With low noise and fast response, they provide reliable data even in environments with minimal vibration levels.
