Abstract
Condition monitoring is the process of tracking the performance, operational status, and health of equipment, systems, or machines. The most prevalent condition monitoring techniques include acoustic emission, motor current analysis, oil analysis, thermal imaging, ultrasonic testing, and vibration analysis. Different organizations use commonly employed maintenance methods, such as preventive, corrective, and predictive maintenance, to ensure the performance and reliability of their assets in good working conditions. Non-destructive testing (NDT) is a set of techniques to evaluate the integrity and properties of materials, systems, or components without harming or modifying their structure. This article reviews several NDT methods and data collection equipment to allow predictive maintenance (PdM). NDT plays a vital role in several industries by supporting inspecting components, materials, and objects without causing any harm. Its advantages include longer useful life, reduced catastrophic failures, reusable testing, no damage, and lower repair costs.
