Inclinometer based on magnetoresistive and tilt sensors

Currently, a high precision, small volume, low cost inclinometer is needed in the coal-bed logging. A new type of inclinometer is designed based on the magnetoresistive and tilt sensors. The vertex angle and the azimuth angle is defined in the geographical coordinates and the exploring probe coordinates, the computing formula for vertex angle and azimuth angle is deduced, and the vertex angle and azimuth angle is calculated real-time by the MCU programme. This inclinometer has been used successfully in the coal-bed logging, and it can satisfy the engineering requirements.
