Acoustic imaging cameras are a recent technological breakthrough in condition monitoring. They use multi-frequency ultrasound sensors and digital imaging to provide reliability practitioners with an acoustic image that depicts precisely where an ultrasound source originates from.

​

Acoustic imaging cameras detect high-frequency sound waves that are emitted by machinery. These sound waves are then converted into images that can be analyzed by reliability practitioners to identify faults in the machinery.

The technology behind acoustic imaging cameras is complex, but the basic principle is simple. The ultrasound sensors detect sound waves that are emitted by machinery. These sound waves are then converted into images that can be analyzed by reliability practitioners to identify faults in the machinery.

​

Acoustic imaging cameras are used to detect a lot of faults found in machinery used in various manufacturing processes. These faults can include compressed air or gas system leaks, steam leaks that are not visible within a steam system, electrical faults such as partial discharge, arcing, and fugitive emission management in the oil and gas industries.

​

Acoustic imaging cameras are becoming increasingly popular in the manufacturing industry due to their ability to detect faults that are not visible to the naked eye. They are also more accurate than other condition monitoring techniques such as vibration analysis and oil analysis.

​

Acoustic imaging cameras are equipped with a microphone array, also known as a group of microphones, that simultaneously collects and processes signals to create a representation of the location of sound sources. There are various microphone array structures available to support specific analysis needs. Additionally, some acoustic cameras come with an embedded visual camera that provides an image over which the acoustic localization information can be presented.

​

The process of acoustic imaging begins with the detection of high-frequency sound waves that are emitted by machinery. These sound waves are then captured by the microphone array of the acoustic imaging camera. The captured sound waves are then processed to create an acoustic image that depicts precisely where an ultrasound source originates from.

​

The process of creating an acoustic image involves several steps. First, the sound waves are captured by the microphone array of the acoustic imaging camera. Next, the captured sound waves are processed to create a time-frequency representation of the sound field. This representation is then used to estimate the location of the sound sources.

​

The location of the sound sources is then used to create an acoustic image that depicts precisely where an ultrasound source originates from. This image is then analyzed by reliability practitioners to identify faults in the machinery.

​

Acoustic imaging cameras are used to detect a wide range of faults found in machinery used in manufacturing processes. These faults can include compressed air or gas system leaks, steam leaks that are not visible within a steam system, electrical faults such as partial discharge, arcing, and tracking, fugitive emission management at oil and gas facilities, and much more.

​

In summary, acoustic imaging cameras use multi-frequency ultrasound sensors and digital imaging to provide an acoustic image that depicts precisely where an ultrasound source originates from. They detect high-frequency sound waves that are emitted by machinery and are used to detect a wide range of faults found in machinery used in manufacturing processes. Acoustic imaging cameras are becoming increasingly popular in the manufacturing industry due to their accuracy and ability to detect faults that are not visible to the naked eye.
