Navigation-grade quartz accelerometer, ±60g, <220 µg bias repeatability, with temperature compensation.
AI-Q-2020 Navigation Grade Quartz Accelerometer (±60g, 220 µg)
Navigation-grade quartz accelerometer, ±60g, <220 µg bias repeatability, with temperature compensation.
Description
The InnaLabs AI-Q-2020 is a navigation-grade quartz servo accelerometer with internal temperature sensor enabling temperature calibration and compensation. Features ±60g input range with excellent one-year bias repeatability of 220 µg and scale factor repeatability of 500 ppm, suitable for high-accuracy INS and IMU applications. The 300 Series Stainless Steel housing (Ø25.45mm, 71g) provides 250g shock survival. Operating temperature range -55°C to +95°C with ≥300 Hz bandwidth and analog current output. Better axis misalignment repeatability (≤100 µrad) compared to the AI-Q-2010. An ideal choice for demanding navigation and stabilization applications.
