This series of acceleration sensors are designed for monitoring low and extremely low frequencies of earthquakes, large buildings and bridges. They have the advantages of high sensitivity and low background noise. They are suitable for building vibration monitoring, earthquake detection, bridge structure testing, ground and foundation vibration. Monitoring, geological structure research and other low-frequency vibration testing occasions.
