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.
UAV & ROV Autopilot
Any sensor fixed to either UAV or ROV systems must be light and small and must have a low power consumption. In addition, high shocks resistance is a key element to keep the integrity of the IMU in case of crash. In terms of accuracy, the IMUs integrated on professional drones, should deliver accuracies corresponding to…
North finding is critical for tactical navigation and target orientation localization. It is used either in fixed static observation systems or in hand-held portable devices. MS1000 implements an innovative microelectromechanical design and electronics which unleash unbeatable performances with regard to the long term bias and scale factor repeatability, in-run bias and vibration rectification error (VRE).
Inertial Navigation System Accelerometer
A key challenge for navigation systems is making them smaller, less expensive and more robust while preserving high-end performances grade. The innovative MS1000 accelerometer responds to tactical grade performance requirements due to the excellent bias and scale factor performances.
