The ACMA instrument monitors high frequency Acoustic Emissions (AE) signals naturally generated by the deterioration in rotating machinery. The smart way of detecting and processing these signals gives you condition-related information in the easiest possible form. It is a state-of-the-art Condition Monitoring instrument with extreme sensitivity to developing faults

How does it work? As the mechanical condition of machinery deteriorates, energy loss processes such as impacts, friction and crushing, generate activity that spans a broad range of frequencies. By detecting only the high frequency part of this signal with special AE sensors, it is possible to detect miniscule amounts of activity (e.g. a slight rub, a brief impact or the crushing of a single particle in the lubricant).Whilst ignoring the sounds you can hear the audio spectrum.
