Intrinsically safe hole orientator for mine
1. The built-in LED screen display the opening pitch angle,roll angle and azimuth angle;
2.High-precision three-axis fiber optic gyroscope is used for north finding,with high accuracy in measuring opening and the azimuth,and is not affected by magnetic field;
3.It has the function of quickly determining the true opening azimuth,and the function of continuous true horizontally rotatable angle measurement;
4.Light,portable and eazy to use.
1. It uses high-precision fiber-optic gyroscopes to sense the earth’s rotation rate,and uses accelerometer for tilt compensation to rapidly and independently determine the true horizontally rotatable angle of drilling.
