SARA SA12: TRIAXIAL MEMS ACCELEROMETER
The SA12 is a cost-effective MEMS-based seismic-grade accelerometer, ideal for strong-motion monitoring, vibration monitoring, structural health monitoring (SHM), and operational modal analysis (OMA).
Description
The SA12 is a cost-effective MEMS-based seismic-grade accelerometer ideal for strong-motion monitoring, vibration monitoring, structural health monitoring (SHM), and operational modal analysis (OMA). This sensor is compact and lightweight. It has been in operation for several years, and is known for its high robustness and shock resistance.
With an analog, true differential output, it can be used with relatively long cables, and is compatible with various data acquisition systems (DAQs). The SA12 is available with either cable or connector output options. It comes with an optional mounting plate.
