Monitoring the structural health of bridges is crucial as it directly impacts safety and longevity.
Dewesoft has developed MEMS-based vibration sensors specifically designed for bridge vibration monitoring. The Dewesoft IOLITE-3xMEMS-8g sensor offers many advantages:
- MEMS technology: This allows the sensor to detect extremely slow vibrations, starting from DC frequency, making it ideal for structural health monitoring.
- Low noise level: Designed for detecting very small vibrations, the sensor has an extremely low noise level of 25 µg/√Hz (or 0.7 µg/√Hz for the high-end version).
- Velocity and displacement measurement: The Dewesoft X software enables the calculation of velocity and displacement values based on vibration signals.
- Perfect ynchronization: These sensors use EtherCAT communication, ensuring signal synchronization at a precision of 1 µs.
- Distributed architecture design: Sensors can be placed up to 50 meters apart using cost-effective CAT6 cables. When combined with optical converters, signal transmission can reach up to 20 km while maintaining synchronization.
- Sensor and DAQ are in one equipment: This reduces costs by 30-40% compared to traditional monitoring solutions.
