Product Description
LKF-MSN300H High Dynamic MEMS North Finder
Product Overview
The LKF-MSN300H MEMS inertial North Finder employs a strapdown north-finding scheme with integrated MEMS gyroscopes and accelerometers. This product continuously tracks and measures changes in well deviation angle, tool face, and azimuth angle, featuring continuous rotation attitude measurement capability.
Designed with a standalone structure, the LKF-MSN300H integrates high-performance MEMS gyroscopes and accelerometers. The vibration-damping design ensures accurate measurement of carrier angular and linear motion parameters even in harsh environments, providing users with a cost-effective and highly reliable solution.
