Digital and wireless Operating Deflection Shape (ODS) for assets condition monitoring

The maintenance of industrial assets is responsible for a large part of the costs of an industrial plant. In this context, low-cost sensors were developed to measure physical quantities and enable online monitoring of assets. Most of these sensors use vibration measurements as a method for detecting and diagnosing faults or behavior deviations. This paper shows a method for using the Operating Deflection Shape (ODS) vibration signal analysis technique in conjunction with low-cost wireless condition monitoring IoT sensors. The developed method was confronted with commercial devices that perform traditional ODS, thus, laboratory and field validations are presented.
