SI1000 is a high-end capacitive MEMS accelerometer specially designed for Strong Motion Class B seismic measurements. It provides extremely low noise, excellent linearity and temperature stability, wide frequency response in an small form-factor and hermetically sealed package. SI1000 guarantees very accurate and stable seismic measurements, requiring neither recalibration nor maintenance during the lifecycle of the system.
