Model Number:
LKF-MEMS Accelerometer
Introduction
MXD is a high-performance MEMS dual-axis accelerometer, independently developed by Liocrebif Technology with full localized production (ensuring supply control). It offers high-speed sampling, static/dynamic error compensation (full-temperature for zero drift, scale factor, installation errors) and correction algorithms, boasting excellent accuracy and stability in complex environments. Compact, easy to integrate, it fits space-constrained platforms, applicable to aerial surveying, inertial navigation, UAVs, robots, intelligent vehicles and bridge monitoring.
Technical Specification
Fully localized design with full-process control (core craftsmanship to packaging/testing) ensures supply stability and traceability. Integrated static/dynamic error compensation reduces zero offset and temperature drift, boosting accuracy and adaptability. Compliant with ISO9001 and GJB standards, ensuring consistent performance and high reliability in long-term use. System-level integration and optimization capabilities enable tailored solutions for diverse platforms, facilitating precise, efficient inertial navigation.
