BRIDGING THE GAPS WITH USED OIL ANALYSIS AND NDT TECHNOLOGIES

Used oil analysis has long been a tried-and-true method for machine health condition monitoring. However, it does have its limitations.

Therefore, embracing the inherent strengths of additional ancillary non-destructive testing (NDT) technologies provides a holistic approach and places your organization in a place to further succeed.

This isn't an either-or type of consideration. Incorporating elements of each can strengthen the foundation of an end user's current condition monitoring program, regardless of its current stage or level of sophistication.

In this article, we'll discuss the traditional concept of used oil analysis the "why's", the "when's", and the "what can be improved upon" compared to the status quo.

In addition, you'll learn about three NDT technologies: vibration analysis, infrared (IR) thermography, and ultrasonics. We'll discuss the various strengths and challenges with each, and most importantly, how these applications complement one another on your journey to operational excellence.

Traditional Used Oil Analysis

Regardless of the maintenance, reliability, or condition monitoring program you have, oil analysis is one of the oldest, most economical, and most effective technologies available, and it should be the base for your entire program.

In my three decades of experience, oil analysis has been the primary tool in my arsenal, allowing me to catch and diagnose impending failures with great success. As with any NDT, it requires end-user expertise; they must have intimate domain knowledge to extrapolate the data and provide insights that can lead to corrective actions and predictable outcomes.
