| A custom instrument designed to minimize errors of tilt detection (based on acceleration measurements) due to misalignments of the employed microelectromechanical system sensors is presented. Owing to special housing, the sensors can be easily aligned and calibrated, and the instrument can be precisely mounted in the end device that utilizes tilt detection. The procedure of a standard calibration for the sensors is briefly described, and a novel method of their alignment is discussed. Thus, a new computation-efficient solution for the precise determination of dual-axis tilt using low-cost accelerometers is introduced. A related application of the instrument (monitoring of axial run-out) is mentioned. |
