The precise monitoring and maintenance of machines and systems are decisive factors for the quality and reliability of industrial processes Our solutions - the Acoustic Camera and vibration analysis software - offer machine builders and maintenance technicians highly developed tools for quickly identifying sources of faults, detecting wear at an early stage and optimising operating processes These technologies enable targeted fault diagnosis and support the continuous operation of your machines - a basic prerequisite for economical and efficient work

Sound fingerprints for analysing machines and systems

In complex environments with numerous noise sources, it is often a challenge to obtain specific information about individual noise sources This is where the acoustic camera offers the perfect tool for precisely locating, identifying and analysing noisy areas Whether for noise reduction, to compare different machine models, for environmental protection and safety or for maintenance - the Acoustic Camera provides detailed insights and promotes targeted measures that optimise the operation of your systems in the long term.

Advantages

  • Early detection of wear and defects
    Recognise potential faults caused by unusual noises or vibrations before they lead to major damage. This reduces downtime and minimises repair costs.
  • Quick and precise fault localisation
    The Acoustic Camera visualises sound sources in real time and thus shows exactly where noises or vibrations occur. This enables immediate and precise problem identification.
  • Easy integration into maintenance processes
    Our software can be seamlessly integrated into existing maintenance and monitoring systems and supports automated fault analysis. Technicians can access the data and initiate measures without expert knowledge.
  • Non-destructive testing and condition monitoring
    The acoustic and vibration properties are analysed non-destructively and in real time, which means that ongoing production is not affected.

Precise localisation of noise sources with Octagon

The measurement on a milling machine shows how precisely noise and vibration sources can be localised in machines and systems. The Acoustic Camera Octagon enables noise to be localised with millimetre precision and creates an acoustic map in just a few minutes. Noise sources are visualised on images or videos of the machine, providing valuable insights, particularly in noisy and complex environments. The integrated microphone array and the powerful NoiseImage software capture frequencies from 30 to 24,000 hertz, allowing even short-term and transient disturbances to be precisely recognised.

Magnifying vibrations with WaveCam

WaveCam supplements this analysis with a special vibration visualisation. Often invisible vibrations that indicate mechanical problems are visualised and greatly magnified by an innovative AI-supported video analysis. This allows engineers to identify critical movement patterns and deviations in real time and initiate targeted measures for optimisation and maintenance - an effective solution for ensuring machine stability and performance.

Ultrasound is one of the main indicators about Condition Monitoring, the Acoustic Camera can be your tool to finding defects that can lead to asset failure.  Use the powerful results, going deep in the frequency analysis, applying advanced algorithms and filtering to save money in your industrial process. Even in rotational machine, don´t forget that you can add external sensors like tachometers to the gfai tech data recorder.

Visualize sound emissions like frictions, impacts, air leaks, or fluid flow inside tubes will help you to quickly identify costly energy waste.

Products related to energy generation can be analyzed by the Acoustic Camera from a different perspective too: Noise Reduction. If you know where your noise spot is and the related frequency range, it will be easier and more effective to develop useful solutions and develop quiet products and plant for examles electric transforms, compressors, wind turbines.

WaveCam — Video Vibration Analysis of a Loudspeaker

Changes in the vibration pattern can indicate damage to the structure. Analyze your vibration data in the time and frequency domain to monitor machines, buildings and structures. The results will help you detect damage faster increase productivity by reducing machine downtime or even improve the life of a product. We tested the entire measurement process on a loudspeaker. Never before has a vibration test been completed faster. The excitation was done with a sine sweep. The recorded video data was amplified in motion by software. The results are extremely precise compared to classic sensor systems.

Our Acoustic Camera and vibration analysis software provide machine builders with a powerful tool for fault prevention and process optimisation. They support optimum system availability, a longer service life for machine components and increased productivity - essential advantages for modern requirements in mechanical engineering.

  • Drive trains and gearboxes
    Vibration analyses can be used to identify damage to bearings, gears or couplings at an early stage so that targeted maintenance measures can be planned before a cost-intensive failure occurs.
  • Pumps and compressors
    The Acoustic Camera can help to detect air or fluid leaks in pump systems, which are often caused by material fatigue or faulty seals. This ensures that the efficiency of the systems is maintained.
  • Electric motors
    Vibrations in electric motors can indicate rotor or bearing problems. The combination of acoustics and vibration analysis enables precise and fast diagnosis in order to extend the service life of the components.
