Limitation of Human Perception

The human ear can only perceive sounds in the range of 20 Hz to 20 kHz. However, hidden faults such as gas leaks, bearing wear, and electrical discharges often emit much higher frequency ultrasound (>20 kHz) — sounds that are imperceptible to the human ear and beyond the capabilities of traditional stethoscopes or microphones.

How does it work?

• Microphone Array: Simultaneously captures sound signals from multiple sources to enhance spatial accuracy.
• Beamforming Algorithm: Focuses on sound sources from specific directions, filtering out environmental noise.
• Acoustic Image Overlay: Displays sound source locations as a heatmap over the image.
• Low-Latency Rendering Engine: Enables near-instant response, ideal for continuous inspection scenarios.

Beyond What's Audible

The FOTRIC TD2 acoustic imaging camera can detect not only audible sound (20Hz-20kHz), but also high-frequency ultrasonic signals that are beyond the range of human hearing. This means it can easily capture things like:

Tire air leaks

The TD2 quickly visualizes and locates tire leak points without the need for soap spray–precise, efficient, and easy to use.

Compressed Air System Leaks

As gas leaks emit high-frequency turbulence noise, the TD2 can quickly detect even the smallest leaks in compressed air pipelines.

Vacuum System Leaks

The TD2 precisely captures subtle leak sounds in vacuum systems that human ears cannot hear, enabling fast leak localization without contact or damage to equipment.

Loose Joint Vibration During Operation

The TD2 detects abnormal high-frequency sounds caused by loose screws while equipment is running. It visualizes and pinpoints the issue in real time without requiring a shutdown, helping maintenance teams address risks and ensure operational stability.
