ZITN 150°C/175°C DS750 High-Temperature Directional Sensor consists of a 3-axis fluxgate magnetometer and a 3-axis accelerometer.The hole deviation angle and gravity tool face angle are measured by the 3-axis accelerometer. After measuring the hole deviation angle and gravity tool face angle, the azimuth angle is calculated by combining the measured values of the 3-axis fluxgate magnetometer. The measurement accuracy of the hole deviation angle is ±0.1°, the measurement accuracy of the azimuth angle is ±0.3°, and the maximum measurement accuracy of the gravity tool face angle is ±0.2°.
In addition, ZITN 150°C/175°C DS750 High-Temperature Directional Sensor can also measure the sum of gravity, sum of magnetic field, magnetic tool face angle, geomagnetic dip angle, and temperature, which can meet the requirements of Logging While Drilling (LWD).
