Product Introduction
Company's Quartz Accelerometer is a high-performance single-axis torque-feedback sensor built on an advanced quartz flexure structure with closed-loop servo technology. It precisely detects external acceleration and outputs a proportional current signal via a high-precision demodulation circuit. Designed for extreme environments, it delivers superior high-temperature, vibration, and shock resistance. Widely deployed in aerospace high-precision navigation, oil drilling inclination measurement, and geological exploration, it provides reliable, accurate measurement under complex operating conditions.
Unique Technology
Company is a high-tech enterprise with full closed-loop capabilities from fiber winding equipment and coils to FOGs, fiber/Quartz Accelerometer inertial products, IMU circuits, software, and test equipment. End-to-end process control improves quality and reduces costs. Operating under ISO9001 with strict processes, it ensures product reliability and consistency.
