DTG-E2 Gyroscope for dynamic well logging

two DTG with two circuit boards.jpg


DTG-E2 is specially designed for borehole drilling field which has overcame the following technical difficulties, especially its operating temperature up to 100 degree centigrade. Inertial devices are more adaptable and better applied in the drilling field than they are in aviation field due to its ability of working in poor conditions. The life of DTG and its adaptation in temperature are specified, especially when it was used in higher temperature.
