Condmaster Ruby Module SPM HD Expert
SPM HD Expert is a complement to SPM HDm/HDc and LR/HR. Advanced digital technique, RPM-based sampling frequency and measuring time automatically adjusted to RPM makes SPM HD particularly well suited for measurement on low-speed applications. Extraordinary signal quality and 24 bit A/D conversion provides razor-sharp resolution and exceptional detail in spectrums and time signals.
The SPM HD method produces different types of results:
- HDm/HDc are part of the Condmaster Ruby platform
- Time Signal HD is extremely useful to locate where in the bearing a possible damage is located. In many cases it is also possible to determine the nature of the damage (cracked inner race with spalling all around or a single crack etc.). The Time signal HD is a result of very advanced digital algorithms where repetitive shocks are enhanced and random signals are suppressed.
- SPM Spectrum HD is the result of applying FFT algorithms on the Time Signal HD. The SPM HD spectrum is useful to determine where a possible bearing damage is located. It is also useful for trending purposes (applying symptom and band values).
High Definition Order Tracking is a function used with Leonova Diamond, Leonova Emerald and Intellinova, primarily for analysis on variable speed machines. The method uses multiples of rotational speed (orders), rather than absolute frequency (Hz). The number of orders to be covered is input by the user. HD Order Tracking also minimizes the risk of smearing in the spectrums.
Condition Manager enables users to experiment freely in or-der to find the optimal alert setup for any given application. This “learning phase” can continue until the criteria is saved. When it is saved, the criteria is activated and Condmaster starts to evaluate measuring results according to the criteria setup. If at some later time it turns out the alert settings yield unsatisfactory results, the criteria can be edited.
