Industrial Acoustic Imaging Camera

Making “invisible” faults fully visible.

Introduction

On industrial sites, hazards such as gas leaks and partial discharge are often “silent and invisible,” yet they threaten both safety and efficiency. Our Industrial Acoustic Imaging Camera “translates” sound waves into visual images, letting you lock onto the fault point at a glance.

Working Principle

The device incorporates a high-sensitivity microphone array (>200 channels, bandwidth >100 kHz) that acquires spatial sound waves in real time; through phase difference and beamforming algorithms, it precisely computes the sound source position and overlays it on the visible-light image to generate a colored acoustic image contour map—the deeper the color, the greater the sound intensity, making the severity of the fault clear at a glance.

Product Highlights

Real-time imaging, second-level response

Imaging speed < 0.1 second, dynamically capturing transient sound sources and multiplying inspection efficiency.

Ultra-long distance, assured safety

Maximum detection distance up to 200 m (50 m for leak detection), enabling safe operation at height, on live equipment, and in confined spaces.

Intelligent noise reduction, strong interference rejection

Built-in digital filtering and scene recognition algorithms ensure precision even under complex operating conditions.

Lightweight and durable

Total unit weight < 1.4 kg, equipped with GPS, Wi-Fi, Bluetooth, and 4G/5G, making outdoor work effortless.

Dual-mode on one screen (optional infrared module)

Acoustic images and infrared thermal images can be displayed on the same screen, coordinating acoustic and thermal diagnosis for more comprehensive assessment.

Core Technical Parameters

Notes: (1) The “localization accuracy: centimeter level” figure is quoted without a distance premise; angular resolution implies that accuracy degrades with distance, so the applicable distance range is to be specified (see the appendix, Section 3, item 1). (2) The “>100 kHz” bandwidth and the “>200 channels” figure are quoted without the array’s sensitivity, signal-to-noise ratio, or angular resolution (see the appendix, Section 3, item 3). (3) The 200 m maximum detection distance is to be qualified by frequency band and test conditions, as ultrasonic attenuation in air constrains the achievable range at high frequencies (see the appendix, Section 3, item 2). (4) The 0.5 m – 200 m detection distance and the 0.5–50 m leak-detection range are quoted as stated in the source; the two ranges are frequency- and source-intensity-dependent. (5) The infrared module is optional; the base configuration does not include it.

Typical Application Scenarios

Gas leak detection

Applicable to more than a hundred types of process gases, flammable and explosive gases, and toxic and harmful gases, including compressed air, steam, alkanes, hydrogen, coal gas, CO, and NH₃.

Even minute leaks can be captured with clear acoustic signature characteristics and localized rapidly, dispensing with the outdated practices of soap-bubble testing and manual listening.

Power partial discharge detection

Supports the identification of three typical types of partial discharge—corona discharge, surface discharge, and floating discharge—and displays PRPD patterns in real time to assist in determining the discharge type.

Applicable to substations (500 kV / 220 kV / 10 kV), distribution network lines, switchgear cabinets, cable joints, insulators, pole-mounted circuit breakers, and pad-mounted transformers, among other scenarios; it can provide early warning at the stage of incipient equipment degradation, before heat is generated.

Significant Advantages over Conventional Detection Methods

Additional capabilities

• Integrates acoustic imaging and infrared thermal imaging for multiple functions in one device;

• Supports Bluetooth headphone listening assistance, smoothing the transition from conventional habits;

• Features out-of-field-of-view edge indication to guide rapid searching for sound sources;

• Provides a focus window to mask irrelevant areas for more precise localization;

• Built-in software with multiple scene presets (leak detection, partial discharge, etc.) for one-touch adaptation.

Conclusion

Let hazards “speak”; let safety be seen.

The Industrial Acoustic Imaging Camera is your ideal partner for on-site inspection, preventive maintenance, and emergency troubleshooting.
