Product Introduction
The HEC375 magnetic continuous inclinometer uses high-quality accelerometers and magnetic sensors as its core components to collect the three-dimensional components of the Earth's gravity field and magnetic field, perform real-time calculations underground, and continuously and accurately measure the wellbore trajectory in three-dimensional space. The system adopts an attitude calculation method based on aerospace inertial navigation technology, which ensures the accuracy and reliability of the system through advanced software verification and compensation.
HEC375 is specially optimized for applications in the field of petroleum geology inclinometer, making it very suitable for inclinometer systems. HEC375 can manually or automatically output inclination angle, azimuth angle, and tool face angle information, and can also output the current magnetic field component size. Users only need to connect HEC375 to the data transmission circuit to form a high-precision inclinometer. The operating temperature of HEC375 can reach 125 ° C, and through advanced temperature compensation algorithms, HEC375 can output high-precision angle values throughout the entire temperature range.
HEC375 has the characteristics of small size and low power consumption, making it more suitable for power volume sensitive measurement systems. HEC375 has been widely used in various fields such as petroleum logging, antenna pointing, vehicle navigation, attitude systems, etc.
