SPM Instrument's HD ENV vibration enveloping technique detects early stage gear and bearing faults

SPM Instrument announces the launch of HD ENV, a high definition vibration enveloping technique for detection of early stage gear and bearing faults. Capable of detecting at an early stage such machine problems which are generally difficult to find in good time with conventional non-enveloping techniques - for example gear and bearing damages - the method utilizes algorithms for digital signal processing, preserving the true highest peak of the vibration signal. Signals buried in machine noise are revealed through high definition digital enveloping, extracting and enhancing the signals of interest from the overall machinery vibration signal.

The unit of measurement is HD Real Peak, a scalar value expressed in decibels. Representing the true amplitude levels found in the envelope signal, HD Real Peak is the primary value to use for determining the severity of a given damage. It is also used for triggering alarms. Using order tracking and symptom enhancement, applying FFT on the signal is very useful to determine the source of the signal. Spectrums and time signals are marvels of clarity, providing a snapshot of machine condition to give the maintenance department a heads-up on potential problems.

The setup of HD ENV measurements in the diagnostic software is straightforward. A set of predefined filters are available for easy selection; each designed to detect damages or anomalies in different stages of development. HD ENV can be used to monitor applications in the 15-20,000 RPM range.
