XCC-3-A Quartz Flexure Accelerometer is a high-reliability inertial sensor designed for navigation, stabilization, and control systems requiring medium to high precision and robust performance under harsh environmental conditions.
The accelerometer provides a measurement range of ±50 g with a threshold sensitivity better than 5 μg, enabling accurate detection of low-level acceleration signals. It features a scale factor of 1.30 mA/g (±0.2) and controlled bias, nonlinearity, and repeatability characteristics, making it suitable for precision inertial applications. XCC-3-A demonstrates strong short- and long-term stability, including ≤20 μg short-term stability (4 h) and ≤50 μg bias composite repeatability (1σ, 1 month). Scale factor and nonlinearity composite repeatability are tightly controlled, ensuring consistent performance over time.
Temperature performance is optimized across the full operating range, with low bias and scale factor temperature coefficients (≤±50 μg/°C and ≤±50 ppm/°C). The device supports customizable internal temperature sensors, such as AD590 or PT1000, to meet specific system integration requirements.
Designed for demanding environments, XCC-3-A withstands 10 g vibration (20–2000 Hz) and 150 g shock, operates over a temperature range of –55°C to +85°C, and offers a natural frequency of 400–800 Hz with a bandwidth up to 2500 Hz.
With a compact Ø25.4 × 30 mm form factor, weight ≤80 g, and low power consumption (≤20 mA at ±12 to ±15 V supply), XCC-3-A is well suited for space-constrained inertial systems requiring precision, stability, and environmental robustness.
