Measurement algorithmic adjustment of 2-axis inclinometer in borehole inclinometer

Introduced application of the SCA100T2-axis inclinometer which belongs to the VTI technology of the Finnish.In order to measure angle,it will be greatly improved in stability,durability,accuracy and reduce volume.The angle measurement causes the question of the algorithm correction in 2-axis inclinometer.Through using the calibration data can obtain regression model of the angle value.The value exists certain measurement error,through the application of error compensation methods can reduce measurement error.The theory analysis and computer simulation show the maximum quadratic mean deviation of the compensation is 0.152 58 and that off-the shelf algorithm of compensation is 4.811 04.It is obvious that the method is efficient.
