For oil field
LKF-MSN300 MEMS inertial attitude measuring instrument adopts a strapdown navigation scheme composed of built-in high-precision MEMS gyroscope and MEMS accelerometer, which can directly point the azimuth angle, tilt angle and rolling angle of the logging hole. The range and bandwidth of the gyroscope and accelerometer of the sensor can be configured according to different user needs.
Fault diagnosis technology (customizable)
According to the needs of some application scenarios, multiple redundant inertial sensors are integrated in the module, which can realize fault diagnosis of product output and ensure the reliability of product work.
High quality and reliability
The company can effectively improve product quality and reduce system costs by comprehensively controlling upstream and downstream processes and technologies. At the same time, the company implements ISO9001 and GJB quality systems, and adopts strict processes to ensure the reliability and consistency of product performance.
The working temperature of the internal components of the attitude measuring instrument can reach 125℃, which well meets the relevant requirements of oil drilling measurement.
