Acoustic Emissions Analysis

Vailen

German acoustic emissions company

Waveform-based analysis, such as FFT, wavelet transform, enhanced feature extraction and pattern recognition provides additional information about, e.g. source mechanisms, damage evaluation or wave propagation.

Neuron Soundware

AI-driven acoustic monitoring with easy-to-deploy sensors. Strong in logging, cloud analysis, and real-time alerts for any asset type.

Nanoprecise

Wireless IoT solution, acoustic plus vibration plus environment sensing. Rapid installation (up in days), strong in hazardous industries, provides Remaining Useful Life predictions.

Vibration Analysis

Fluke

Fluke 810 is the preferred tool, and it costs ~$15k/unit. In addition, it requires trained, manual use on the machines, taking measurements that attach to the machine in multiple locations (after inputting into the Fluke 810 the design of the system). The Fluke 810 gives you a diagnosis assessment for different bearings, which is a good offering. It has 800 lines of FFT resolution, which means if you are sampling at 40 kHz, your resolution is 50 Hz.

Fluke 805 is a small meter that looks like a pen, but they emphatically declare that it is not. It is designed for go/no-go measurements. It has 100 Hz frequency resolution, which is not enough for detailed analysis, and does not provide any way to store the data for later analysis.

Vibration analysis and AI

Trigger	Frequency	Amplitude	Comments
Unbalance	1 x RPM	Proportional to the imbalance, greater in the radial direction	Usually appears in the first harmonic
Misalignment/Bent shaft	1/2/3/4 x RPM	Large in the axial direction	Misalignment between bearings
Clearance in the bearings	1/2 x RPM	Large in the vertical direction	As the frequency is less than 1/2 amp, phase can be variable
Lack of mechanical firmness	2 x RPM	Unstable	Usually affects the alignment
Loose straps	1 x RPM	Unstable	-
Defective gears	High	"Blips"	Frequency between 15-40 kHz
Deteriorated bearings	High	"Blips"	Frequency between 15-40 kHz
Lubrication	High	-	The amplitude changes significantly due to the lubrication
Twisted shaft	1 x RPM	Large in the axial direction	The amplitude can be present in a pulsatile form

Electric motor guide

Tractian does not appear to do the analysis for you — it looks like they give you the tools to do it yourself.

Fracttal

Triaxial vibration sensor samples at 3.2 kHz, which means it can only detect frequencies up to 1.6 kHz, which is low.
