Portable acoustic camera
Find the sources of mechanical fault sounds
during the inspection of operating equipment.
The camera displays the location of the sound source on the equipment image. The "Mechanics" mode helps assess the nature of the sound based on acoustic excess and acoustic spikes.
Tasks of acoustic diagnostics
Bearings
Locate the sound of a running bearing
and assess for signs of wear or damage
lubrication by acoustic signal.
Electric motors
Locate the sound source
in a running electric motor without stopping
equipment.
Rotating knots
Find the source of sound in drives, couplings, and other mechanisms. Evaluate the signal's nature based on acoustic excess and peaks.
Noise research
Ultrasound imaging in a selected frequency range. Source detection, room and vehicle surveys, acoustic testing.
Mechanic mode
Localization of the source and assessment of the nature of the sound using two acoustic parameters.
Acoustic excess (AE)
Characterizes the severity of peaks in the acoustic signal. An increase in this indicator may indicate insufficient lubrication or increased wear.
Acoustic burst (AB)
Characterizes pulse spikes in the acoustic signal envelope. An increase in this indicator may indicate lubricant contamination or component damage.
Color indicators help track indicator progress. Sensitivity can be adjusted separately for each parameter.
Hear the difference
Compare a regular microphone and the NAC-PA camera:
Listen to the general background, then isolate the sound of a particular source.
From survey to report
Find the source and save the survey results.
-
Find the source
Point the camera at the equipment - the acoustic map will show the location of the sound source.
-
Save the result
Record the image and measurement results for further analysis.
-
Prepare a report
Generate a report on the saved data in Aura SVS software and submit the results to the operations department.
