Sound imaging used with ultrasound instruments such as the Ultraprobe 10,000 and Ultraprobe 15,000 is rapidly becoming accepted as an important component to ultrasound condition monitoring programs. The ability to both hear the sound as it is played and view it on either the FFT, Time Series or Waterfall screens provides the inspector an added dimension that cannot be overlooked. There are times when sound quality can add to understanding a potential issue that just viewing a screen might miss. One can equate this to viewing a silent movie versus an HD video with sound effects. Plus this element extends ultrasound diagnostics to all the major applications, not just mechanical inspections. You can analyze anything that produces detectable ultrasound. This can be lubrication related issues, bearing trending, valve analysis, steam trap testing, electric fault analysis, arc flash potential and even leaks. If you are a vibration analyst, you can fully appreciate the time it will save. You only need to capture data from one test point and you can hear the sound in real time as you record.
There are useful tools built in, such as overlays, harmonic cursor, two movable cursors and annotation that make it easy to review and analyze sounds. The overlays enable users to compare one sound sample to another. These can be saved in a folder to be used for historical reference or as a training device to understand what one should look for when reviewing and comparing new sound samples.
The new bearing fault calculator is useful in diagnosing the fault frequency as it relates to inner race, outer race, ball pass or cage. In addition it has a feature to calculate the RPM which is helpful in determining whether or not the motor is rotating at the proper speed.
The Ultraprobe 15,000 has on-board spectral analysis. Sounds can be analyzed in the field viewing any of the FFT, Time Series or dual screens. The sound and the image of the screen can be stored and entered into a report. The Ultraprobe 10,000 has on-board sound recording. Sound and data can be transferred to Ultratrend DMS and viewed in UE Spectralyzer where the results can also be entered into a report.
