Seismic Sensor SI1000
HIGH-END CAPACITIVE MEMS Accelerometer
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.
Identify Hazards For Critical Civil Infrastructure
The SI1000 helps to monitor and identify seismic vibration hazards that could potentially threaten the safety and operability of critical civil infrastructure – such as dams, bridges and buildings. Any slight seismic motions can be detected and measured with the high precision of the SI1000 MEMS Accelerometer.
One of the most impressive advantages is the excellent long-term bias and scale factor repeatability, low run-in bias, excellent behavior in vibration (VRE) and low noise. All of these factors allow for very accurate and cost-effective tactical grade measurements.
Built-In Self-Test Function
The built-in self-test mode generates a square wave signal on the device outputs (OUTP & OUTN) and can be used for device failure detection. This can be helpful to prevent system faults before they occur.
