A state of the art review of online condition monitoring tools using NDT as principal testing technique

The non-destructive techniques are the suitable solution for testing and quality control but in present cut-throat scenario where margin of companies are decreasing and pressure for providing good quality is increasing day by day. Therefore offline condition monitoring techniques are losing their importance. Now the most suitable answer is on-line condition monitoring techniques. In online condition monitoring, machine or a component is constantly observed while it is in operating condition by taking help of sensors. This research paper aims to cover the research work related to online condition monitoring giving emphasis on those research papers which uses NDT as principal condition monitoring tool.
