FOTRIC TD2e Kit Introduction: Handheld Acoustic Imaging Camera

FOTRIC TD2e Kit positions itself as the most efficient entry-level ultrasonic leak detector for daily inspections. Specifically designed for the quick and precise localization of compressed air leaks, gas leaks, mechanical anomalies, and electrical discharges, this acoustic camera is the ideal tool for timely maintenance checks and immediate adoption in high-volume industrial environments.

Thanks to its startup in just 1 second, the device is immediately ready for use in the field. The optimized high-density array, consisting of 64 digital MEMS microphones, guarantees a localization accuracy significantly superior to the past. With an extended frequency range (2–100 kHz), it easily detects both audible sounds and ultrasounds imperceptible to the human ear.

The acoustic source is displayed as a heat map superimposed on the real image captured by the 5 MP industrial digital camera (58° × 45° field of view). To operate smoothly even in the most critical contexts, the TD2e implements the Noise Suppression feature that proactively filters out background noise, and the Peak Mode, essential for isolating specific ultrasonic frequencies and identifying multiple leak points in complex scenarios. With over 3 hours of battery life for each removable battery (IP54) and a large 3.5” touch display, it is the ideal ally for quality control and predictive maintenance of facilities.

What is acoustic imaging?

Limitation of human perception

The human ear can only perceive sounds between 20 Hz and 20 kHz. However, many industrial anomalies such as gas leaks, bearing wear, and electrical discharges generate ultrasounds (>20 kHz) that remain completely imperceptible and undetectable with traditional stethoscopes or microphones.

How does it work?

FOTRIC TD2e uses an optimized array of MEMS microphones to detect and locate high-frequency sound sources. The beamforming algorithm filters out environmental disturbances, displaying the position of the acoustic source as a heat map superimposed on the real image, thus allowing for immediate and precise diagnosis in seconds.

What does the FOTRIC TD2e Kit include?

The FOTRIC TD2e Kit is structured to provide everything needed for continuous inspections in high-intensity industrial environments. The package includes:

• FOTRIC TD2e Acoustic Camera: The main unit comes with an exclusive extended 1.5-year warranty.
• Power System (2x Batteries): Includes two 3.6V / 5000mAh rechargeable lithium-ion batteries. Each battery provides over 3 hours of runtime, easily covering an entire inspection shift. A charging base is included.
• Transport Solutions:
  • Durable Hard Case: Features an industrial-grade shockproof design with a custom-molded internal structure.
  • Soft Bag: For lighter and more flexible transport scenarios.
• Belt Clip: Enhances on-site mobility and safety by allowing the device to be securely attached to a belt or tool pocket.
• Accessories and Connectivity: Type-C cable, 32 GB Micro SD card for data storage, wrist strap, and manuals.

Beyond what is audible

Tire air leaks

The TD2e quickly visualizes and locates leak points in tires without the use of soapy spray: precise, efficient, and easy to use.

Compressed air system leaks

Leaks in compressed air systems emit high-frequency turbulent noises: thanks to the Noise Suppression feature, TD2e detects even the smallest leaks in the ducts by isolating the signal from machinery noise.

Vacuum system leaks

The TD2e accurately captures leak sounds in vacuum systems, even those imperceptible to the human ear, allowing for rapid, non-contact localization.

Loose joint vibrations during operation

The TD2e detects and visualizes in real-time abnormal vibrations caused by loose screws during operation, without the need to stop the plant.

Advanced Features

Acoustic focus (Noise Suppression and Peak Mode)

The exclusive signal processing functions of the TD2e ensure clear diagnoses in critical industrial environments. The Noise Suppression function adaptively filters background interference, while the Peak Mode (or Micro-Detection Mode) isolates ultrasonic frequencies to highlight multiple anomaly points in a single complex scenario.

Source mode switching

The TD2e supports single-source, multi-source, and all-source display modes, adapting instantly to noise complexities.

Sound pressure level measurement

The integrated sound pressure level (dB) measurement allows evaluating the severity of the leak by quickly diagnosing the acoustic sources and facilitating a more structured quality control.
