What is the SONASCREEN 2 and which applications can the acoustic camera be used for?

The SONASCREEN 2 is an acoustic camera for locating, visualizing, and recording sound sources in the audible and ultrasonic frequency ranges.

Its microphone array detects acoustic signals and uses them to generate an acoustic image in real time. The position of a sound source is displayed directly in the camera image. This allows ultrasonic sources to be located quickly without having to inspect individual points one after another using a sensor.

The SONASCREEN 2 detects sound signals up to 100 kHz and features 176 digital MEMS microphones.

Which applications is the SONASCREEN 2 suitable for?

The main applications include:

• leak detection in compressed-air, gas, and vacuum systems,
• detection of electrical partial discharges,
• tightness testing,
• general localization and analysis of audible and ultrasonic sound sources.

Several sound sources can be visualized simultaneously in the camera image.

How is ultrasound displayed?

The SONASCREEN 2 overlays the calculated acoustic image onto the optical camera image.

This makes it immediately visible which area the detected sound signal is coming from.

The selected ultrasonic signal can also be made audible via headphones.

The user can therefore simultaneously:

• see,
• hear, and
• analyze

the sound source.

What is the role of the thermal imaging camera?

The SONASCREEN 2 also features an integrated infrared module for thermal imaging.

This allows acoustic and thermal information from the same inspection situation to be viewed together. Combining both types of information can provide additional indications of the condition of a component or system.

Does the system have to be shut down for the inspection?

Many applications can be performed while the system is operating.

For example, compressed-air leaks or acoustically detectable partial discharges can be inspected without interrupting normal system operation for the measurement.

All safety regulations and required safety distances applicable to the respective system must always be observed.
