The magnetic induction inclinometer sensor is mainly used to measure the azimuth angle of the drill pipe relative to the earth's magnetic field, thereby determining the inclination angle of the drill bit. The following is the basic working principle of the magnetic induction inclinometer sensor:

Magnetic field detection: The magnetic induction inclinometer sensor is equipped with magnetic sensitive elements inside, such as Hall effect sensors or magnetoresistive sensors. These elements can sense the existence of the earth's magnetic field.

Azimuth measurement: When the drill pipe rotates, the magnetic sensitive elements inside the sensor will rotate along with the drill pipe and sense the magnetic field intensity in different directions. By analyzing these changes in magnetic field intensity, the sensor can determine the azimuth angle of the drill pipe relative to the geomagnetic field.

Inclination angle calculation: Since the earth's magnetic field is uniform on the horizontal plane, the inclination angle of the drill pipe can be calculated by measuring the angle between the magnetic field direction on the drill pipe and the horizontal plane. This angle is the inclination angle of the drill pipe.

Data processing: After the sensor converts the sensed magnetic field signal into an electrical signal, it is processed by the built-in electronic circuit and finally outputs a value representing the inclination angle.

Calibration: To ensure accuracy, magnetic induction inclinometer sensors usually need to be calibrated regularly to compensate for the influence of environmental factors (such as the presence of ferromagnetic particles in drilling fluid) on the measurement results.

Data transmission: Modern magnetic induction inclinometer sensors usually have data storage and wireless transmission functions and can directly send measurement data to the drilling control system for real-time monitoring of the drilling direction.

Environmental impact: It should be noted that the presence of ferromagnetic substances may interfere with the measurement of the magnetic field. Therefore, when using a magnetic induction inclinometer sensor, try to avoid the presence of strong magnetic field sources around.
