Inclinometer in borehole
WebSlope inclinometers are geotechnical instruments used to measure horizontal displacements along various points on a borehole. For this reason, sometimes they are also called borehole inclinometers or simply inclinometers. Slope inclinometers are the most important source of geotechnical data during construction (Erikson et. al., 1992). http://pergatory.mit.edu/kinematiccouplings/documents/Papers/three_ball_and_groove_couplings/Precision_Robot_Calibration_Using_Kinematically_Placed_Inclinometers_abstract.pdf
