• Accelerometro Sismico Amd Mems 01

AMD MEMS seismic accelerometer

AMD MEMS strong motion seismic accelerometer suitable for any environmental condition and designed for vibration measurement of bridges and viaducts.

Solgeo has developed this triaxial mems accelerometer with performances suitable for monitoring structures such as bridges, viaducts, tunnels in road and rail environment, both for direct measurement of accelerations and displacements but also suitable for modal analysis of structures.
. It is characterised by high response accuracy, good dynamics especially at low frequencies (those of interest), high robustness to atmospheric agents and shocks, all at a very competitive price for widespread installation. It connects directly to the Dymas24 series acquirers that manage the internal test.
