Ways of adjusting MEMS accelerometers for tilt measurements over a small angular range of few degrees arc or less are considered with regard to achieving a possibly high accuracy. The paper describes some additional mechanical structures applied to overcome the problem of incompatibility between the large measuring range of MEMS accelerometers and the expected small angular measuring range.
The paper deals with a specific type of tilt measurements, where an axial tilt is to be determined. The measurements are realized by means of accelerometers - MEMS devices most preferably. Various mathematical relations between the axial tilt and the Cartesian components of the gravitational acceleration are presented. Each relation is described in detail, especially in the terms of the resultant...
