Mini Size Ø18.8×21 Quartz Flexible Accelerometer with Scale Factor 2.2~3.5mA/g and Bias Repeatability ≤100ug
The quartz flexible accelerometer is a precision instrument featuring quartz glass flexible support and advanced servo circuitry based on inertia principles. When subjected to acceleration, it delivers an output precisely proportional to the input acceleration. With high output impedance in current output form, users can select sampling resistance according to requirements without compromising system stability.
Our quartz flexible accelerometer product line ranges from high-precision μg GSACC111Q models for satellite microgravity measurement to cost-effective, rugged GSACC117Q variants. These instruments serve aerospace, aviation, navigation, marine, automotive, petroleum, and geotechnical applications, providing critical signals for navigation, guidance, control, leveling, and monitoring systems.
