2S3: Accurate condition monitoring of ultra-low and low speed machines

Tim Sundstrom, Manager of Strategic Sales & Application, SPM Instrument AB


Vibration Enveloping has been a valuable tool for the vibration analyst for decades, it provides an earlier fore-warning time compared to the traditional overall velocity measurements.

By using state of the art digital signal processors and innovative algorithms it’s possible to produce results that takes the vibration envelope method to new levels.
Many of the mission critical machines found in the industry today are running with low or ultra-low speeds. It has been seen as very challenging or even impossible to accurately monitor the condition of such machines using vibration based methods.
HD Technology is the perfect choice for condition monitoring of these machines but also to increase the pre-warning times for machines running at more “normal” speeds.
The presentation will cover the fundamentals of bearing damage processes and explain the new technology including plenty of real world examples.
