Model 1521 surface-mount accelerometers from Silicon Designs Inc., Kirkland, WA, with MEMS chip development and fabrication offer up to 2,000 hr. of measurement stability, temperatures to +175°C, with 6,000 g shock survivability and zero signal degradation. Features include non-ferrous construction, nitrogen-damped MEMS sensing element in gold ceramic 20-pin LCC or JLCC package, and 0.5 V to 4.5 V single-ended or ±4 V differential output. Measuring ranges ±2 g to ±200 g, nominal frequency response, 0 to 400 Hz (±2 g) or 0 to 3000 Hz (±200 g), insensitive to temperature changes and gradients, signal output unaffected by electromagnetic interference, and no warm-up period. Applications include shock and vibration measurement, particularly in harsh environments; oil and gas downhole monitoring; UAV inertial measurements; tilt and position measurements for antennas, solar panels, wind turbines, hydroelectric spillway parts; civil structure seismic monitoring; industrial vibration monitoring and analysis; robotics; and machinery control.
