Fotric TD2e Kit

Acoustic Imaging Camera

From ‘Inaudible’ to ‘Visible’

The Fotric TDee Kit transforms ultrasonic sound into clear visual images — allowing you to detect faults instantly, without stopping operations.

Why Choose the TD2e Kit?

  • Detect hidden faults beyond human hearing
  • Visualise sound as a real-time heatmap overlay
  • Fast identification within seconds
  • No shutdown required — inspect while equipment is running
  • High-precision fault localisation

What is Acoustic Imaging?

Limitation of Human Peception

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

Compressed Air System Leaks

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

Vacuum System Leaks

The TD2 Kit 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 Kit 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.

Pneumatic Valve Leakage Detection

As pneumatic valves, cylinders, and  fittings in automated production lines age,  they frequently generate high-frequency  leakage noise. The TD2e Kit captures  real-time ultrasonic leakage signals from  valve bodies and fittings, providing visual  localization to pinpoint leak sources  quickly.

Why Fotric TD2e Kit?

  • High-density microphone array with 64 MEMS digital microphones
  • Industrial digital camera: 5 MP, 58° × 45° field of view
  • ≥ 3 hours of single-battery runtime, removable; device rated IP54
  • Detection distance: 0.3~60m

Professional-grade Features

Multiple Image Modes

Even in noisy environments, sound  sources no longer blur into one. Multisource mode can simultaneously lock  onto multiple abnormal sound points,  automatically distinguish sources with  different frequencies and intensities, and  enable multi-target visualization—making  every issue clearly visible.
