SonaVu Acoustic Imaging Camera
Defects are visible to the human eye with the SonaVu™ acoustic imaging camera.
SonaVu™ detects sources of airborne ultrasound using its 112 highly sensitive ultrasound sensors. Defects are shown on visual images allowing operators to easily pinpoint faults that produce ultrasound.
How it works:
Using its 112 ultrasound sensors and optical camera, it can detect sources of airborne ultrasound and transmit them into a visual image on its touch screen. Defects such as compressed air system leaks, compressed gas system leaks, vacuum leaks, the presence of partial discharge on electrical assets, and failed/working steam traps all create turbulence. And when there is turbulent flow present, there is airborne ultrasound. SonaVu™ makes the superhuman hearing capabilities of SDT Ultrasound Devices visible to the human eye.
Using an acoustic imaging camera, defects and failure modes can be visualized and pinpointed from up to 164 feet away. The visualization capabilities of SonaVu™ make it really easy to use, too. With minimal device training, maintenance technicians can confidently inspect their assets – long before defects cause unexpected downtime.
If it has been some time since your last ultrasound compressed air survey, or you’ve never performed this type of survey at your facility, it’s likely that your compressed air system has leaks. A poorly maintained compressed air system can negatively impact product quality and production efficiency – not to mention impact plant-wide sustainability.
A leaky system will drain resources and harm the environment with greenhouse gas emissions. Performing a compressed air leak survey and locating the leaks has never been easier. And since SonaVu can pinpoint leaks from up to 164 feet, even leaks in hard-to-reach airlines won’t be missed.
Unreliable electrical machines and equipment can cause manufacturers costly downtime and repairs. Even more threatening, they have the potential to injure and kill personnel without warning. Early detection is key! Before an electrical asset reaches the point where a dangerous phenomenon like arc flash and arc blast can occur, there are signs that the asset is becoming unstable.
Partial discharge is the initial sign of a deteriorating electrical asset. The effects of partial discharge produce airborne ultrasound signals, easily detectable with SonaVu™. Find sources of partial discharge on all types of high voltage electrical assets, such as switchgear, transformers, overhead lines, and underground cables.
By simply scanning these high-voltage electrical assets with a SonaVu™ acoustic imaging camera, you’ll be able to locate and document the presence of any partial discharge.
Fugitive emissions are a significant problem for oil and gas production facilities. Emissions are often accepted as part of the industrial process, as they are categorized as equipment leaks and accidents, and equipment failures. But as they leak into the air we breathe, there can be dangerous consequences. While some fugitive emissions just result in unpleasant odors, some can pose a serious safety threat to plant personnel and those living near the facility.
SonaVu™ is capable of detecting fugitive emission gas leaks in most environments. When a compressed gas leaks from a high-pressure pipe or valve or to a low-pressure zone like our atmosphere, there is a differential pressure created which produces ultrasonic turbulence. Scanning hot zones for fugitive emissions with SonaVu™ reveals the sources of dangerous and costly leaks. Additionally, inspectors need not worry about scanning for leaks indoors or outside, as the wind does not affect the ultrasonic detection capabilities of SonaVu™.
There are many safety and environmental regulations around fugitive emissions, and acoustic imaging can be a very helpful tool in compliance.
