Ultra low speed bearing monitoring

The premature failure of bearings in low speed machinery is a notorious problem. The special requirements associated with measurement on low rpm applications have been beyond the limits of established monitoring techniques – until now.

The low-speed challenge

Condition monitoring on machinery operating at low speed is more complicated than on industrial machinery in general. Signals originating from bearing and gear problems are typically low in energy content, jumbled up and practically unanalyzable. Distinguishing these signals from background noise in order to extract meaningful bearing information can be a very difficult task. Measurement data collected at low speeds are often mistakenly dismissed as being ”just noise”. Hence, bearing wear and damage often goes undetected until it is too late.

Extending the scope of predictive maintenance to include condition monitoring at low speeds, SPM HD® is all the bearing monitoring technology you need.

The SPM HD solution

SPM HD makes optimal use of hardware and software capacity for maximized performance. Advanced digital algorithms provide very high dynamics, enabling the method to distinguish the desired signal from background noise. The signal is picked up and enhanced, resulting in a clear and unobstructed view of machine condition.

SPM HD is the result of an intense development effort by SPM Instrument in close cooperation with customers in industry. The method has been field tested successfully on low speed applications such as twin wire presses, screw presses, drying cylinders and wind turbines, some running at only a few revolutions per minute.
