Sound is an important factor of quality analysis; changes in noise output can often be used to detect defects in machinery and plant installations. With the correct instruments, an expert technician can quickly locate these issues. To diagnose flaws and avert dangerous hazards, most plant owners rely on cutting-edge technologies. Technomax would like to introduce you to one such technology that will help maintenance technicians to pinpoint the issues. Sonotec's Acoustic Imager is a portable system that can show complex acoustic information in different colours and detect leaks much more quickly than any other technique. These advanced technologies allow for quick localization and analysis based on a variety of factors.

How does Sonotec’s Acoustic imager work?

The acoustic camera uses distinct colours to locate sound sources and shows complex acoustic information. With the use of beamforming, the device can extend its vision to areas where the human eye is unable to see. The position of the source in wave fields, such as ultrasound fields, can be established using beamforming. It is constructed in such a way that it can be utilised in a range of industrial locations, thanks to the highly sensitive array of 72 microphones and the IP54 protection rating. Because of the overall spiral array architecture, it can span a wide dynamic range. Also, the wide frequency range of Sonotec Acoustic cameras can detect sound waves in both the audible and ultrasonic ranges.

The acoustic imager's secondary advantage is the high-resolution display at a real-time frame rate of roughly 100 frames per second. The camera can perfectly capture fast-moving objects. Users can also focus on different frequencies and bandwidths depending on the application and the generated acoustic waves. The camera detects sound sources at a range of up to 150 metres, depending on the frequency the user is focusing on. We can also change the dynamic range of the camera to mask out sources of interference. The device uses industrial headphones to deliver acoustic feedback back to the user. In addition to the visual inspection, the maintenance staff can also listen to the measurements.

Application of SONASCREEN Acoustic Cameras 

• Detection of compressed air and vacuum 

Larger areas can be searched for leaks quickly with the help of the acoustic imager, saving time and money. The pre-set leak detection profile makes leak detection with an acoustic camera uncomplicated. With the use of these cameras, multiple leaks can also be detected and highlighted at the same time. 

• Electrical asset reliability

The acoustic cameras would allow maintenance professionals to swiftly and accurately detect high-frequency sound sources such as corona or partial discharge. Regular ultrasonic inspections of electrical assets will aid in the early detection of partial discharges and help to ensure plant reliability and safety.
