MEMS DC accelerometers by Silicon Designs Inc. (SDI) offer a superior combination of precision, ruggedness, and long-term reliability for a wide range of defense applications.
Piezoelectric accelerometers have historically been favored for high-frequency operations however, their inability to measure static or low-frequency acceleration can limit their utility in certain defense applications.
SDI’s MEMS DC accelerometers overcome these limitations with static and dynamic sensing capabilities in a single device, providing real-time awareness even in zero-motion conditions.
Combat-Ready Durability
Military environments often involve extremes of impact, heat, cold, and electromagnetic interference. SDI’s accelerometers are designed to maintain data fidelity despite these challenges.
Defining features:
The capacitive sensing mechanism is less affected by temperature variations compared to piezoelectric sensors, reducing the need for added compensation- Low-impedance outputs to reduce signal degradation and noise pickup over extended cable lengths
- An extremely rugged design with no crystal structures to damage
- Low noise and minimal drift ensure that data remains accurate over years with no loss of sensitivity
Manufactured in the U.S., SDI’s sensors are screened to MIL-STD-883 and qualified to MIL-PRF-38534, making them suitable for defense-grade systems. Their analog output design simplifies integration into existing mission hardware, while long-term stability reduces lifecycle maintenance and recalibration costs.
