Electronic Gyroscope Inclinometer, Borehole Inclination and Azimuth Measurement

JTC-2 Dynamical Tuning Gyro Inclinometer (High Precision)

Main Applications and Features:

• Gyro inclinometer is mainly designed for drilling inclination and azimuth measurement of in iron casing in magnetic mine areas. General inclinometer drilling azimuth mainly relies on compass or magneto sensor for orientation; in the magnetic mine area or inside iron casing, due to the effect of magnetic substance, it is difficult to accurately determine the orientation of drilling. Therefore, the most effective way to measure azimuth in strong magnetic environment is to utilize gyro direction method without magnetic interference. Gyroscopes have two categories: mechanical type and electronic type. Mechanical gyroscope has greater zero drift, but short service life, high price. Gyro inclinometer adopts electronic gyroscope, it has advantages like small size, long service life, less zero drift, lower price, etc.
• Gyro inclinometer consists of three parts namely ground instrument, winch (winch controller is required when>300m), downhole probe, with measured data automatic storage, compact instrument size, and simplicity of operation.
