INERTIAL-GRADE SURFACE MOUNT MEMS DC ACCELEROMETERS
Silicon Designs' inertial-grade surface mount MEMS DC accelerometers offer the same durability and reliability as their industrial-grade counterparts, while providing the enhanced specifications required for higher-end and tactical-grade inertial applications, including Allan Variance, long-term bias repeatability, scale factor stability, axis misalignment, and vibration rectification error.
