SHAKE FA335 is a tri-axial force balance accelerometer suitable for bridge deck vibration monitoring. The high-dynamic resolution provides accurate data generated by micro-tremors, loading of heavy traffic, structural vibration as well as earthquakes. SHAKE FA335 can be also applied into high-rise building health and strong-motion monitoring. The voltage outputs of SHAKE FA335 are compatible with digitizers manufactured by Sanlien or any other brands with easy integration.
