Suitability of MEMS Accelerometers for Condition Monitoring: An experimental study

Abstract

With increasing demands for wireless sensing nodes for assets control and condition monitoring; needs for alternatives to expensive conventional accelerometers in vibration measurements have been arisen. Micro-Electro Mechanical Systems (MEMS) accelerometer is one of the available options. The performances of three of the MEMS accelerometers from different manufacturers are investigated in this paper and compared to a well calibrated commercial accelerometer used as a reference for MEMS sensors performance evaluation. Tests were performed on a real CNC machine in a typical industrial environmental workshop and the achieved results are presented.

Application of Single MEMS-accelerometer to Measure 3-axis Vibrations and 2-axis Tilt-Angle Simultaneously

“…In recent year, application of micro electro-mechanical systems (MEMS) accelerometer to detect vibration as well as tiltangle has been widely used in various fields of application, such as in [4]- [8]. Accelerometer sensors made using MEMS are better than their conventional counterparts because they are smaller in size, low power consumption, sensitive to input variations, easy to integrate into systems or modify, and cheaper.…”

“…For example, for testing and analysis of the dynamic movement of a ship [1], investigating active volcano [2], [3], determine the health status of industrial machines [4], [5], and so on. In here, to get simultaneous measurement of vibrations and tilt-angle, will require more then one kind of sensor.…”
