The FOTRIC TD2e Kit converts audible and ultrasonic signals into acoustic images, allowing maintenance engineers to locate leaks and abnormal sound emissions without physical contact with the equipment under inspection.

Its advanced acoustic imaging technology combines a microphone array with digital signal processing algorithms to determine the direction of sound emissions. Acoustic sources are displayed as a visual overlay on the digital camera image, making it easier to identify the origin of industrial problems.

The TD2e Kit is especially suitable for organizations seeking to reduce compressed air losses, improve energy efficiency, locate vacuum leaks, enhance industrial reliability and optimize preventive and predictive maintenance programmes.

Acoustic Beamforming Technology – Make Sound Visible

The Acoustic Beamforming technology processes signals captured simultaneously by 64 MEMS digital microphones to identify the direction of sound sources. It creates acoustic maps that are overlaid onto the camera's live visual image.

This approach helps maintenance technicians pinpoint sound emissions that may otherwise be difficult to locate, particularly in complex machinery, pneumatic systems and installations with multiple background noise sources.

2–100 kHz Audible and Ultrasonic Detection

The FOTRIC TD2e Kit features a 2–100 kHz acoustic positioning frequency range, covering audible sound and ultrasonic emissions beyond the range of human hearing.

Compressed air and pressurized gas leaks often generate high-frequency turbulence noise. By visualizing these emissions, the TD2e Kit helps identify potential leaks in pipelines, connectors, valves and pneumatic systems.

Technicians can manually adjust the frequency range and display peak-frequency information to improve inspection selectivity and support acoustic analysis.

Compressed Air Leak Detection

Compressed air leaks are a significant source of avoidable energy consumption in industrial facilities. Even relatively small leaks in pipes, fittings, valves and pneumatic equipment can increase compressor operating time and overall energy costs.

The FOTRIC TD2e Kit helps maintenance personnel visually locate ultrasonic emissions associated with leaks, reducing the time required to investigate suspected loss points.

It is a practical tool for compressed air system maintenance, industrial leak surveys, energy efficiency programmes and pneumatic equipment inspections.

Vacuum System Leak Detection

Air ingress through damaged seals, fittings and connections can reduce the performance and stability of industrial vacuum systems.

The FOTRIC TD2e Kit detects acoustic emissions associated with vacuum leaks, helping maintenance teams identify potential problems without immediate dismantling of the equipment.

Pneumatic Valves, Cylinders and Actuators

Pneumatic control systems depend on reliable seals, valves, cylinders and connections. Component wear can result in air leakage, reduced efficiency and unstable equipment operation.

The TD2e Kit provides real-time acoustic visualization to help locate high-frequency emissions in pneumatic valves, actuators, cylinders, connectors and automated manufacturing systems.

Mechanical Anomaly and Loose Joint Inspection

Beyond leak detection, the FOTRIC TD2e Kit can help investigate high-frequency acoustic emissions associated with loose bolts, mechanical joints and abnormal vibrations.

Acoustic inspection supports fault localization and helps maintenance teams identify components requiring further assessment, complementing other condition monitoring techniques.

Three Professional Acoustic Imaging Modes

The FOTRIC TD2e Kit provides three acoustic imaging modes for different inspection requirements:

• Single-source: focuses on an individual acoustic source to simplify localization.

• Multi-source: identifies and displays multiple acoustic sources simultaneously.

• All-source: visualizes all detected sound sources within the inspection scene.

Noise Suppression and Micro-Detection Technology

The Noise Suppression mode reduces interference from environmental sounds, improving acoustic source localization in noisy industrial environments.

The Micro-Detection mode helps capture weaker acoustic signals, supporting the investigation of subtle emissions that might otherwise be difficult to detect during conventional inspections.

3.5-inch IPS Touchscreen and 5 MP Digital Camera

The FOTRIC TD2e Kit features a 3.5-inch IPS LCD touchscreen with a 640 × 480-pixel resolution for intuitive navigation and acoustic visualization.

Its integrated 5-megapixel industrial-grade digital camera provides a visual reference for acoustic maps, allowing technicians to associate detected sound sources with specific equipment components.

Designed for Professional Field Inspections

The TD2e Kit offers an IP54 protection rating, industrial construction and a manufacturer-specified design for resistance to drops of up to 2 metres.

The professional kit includes two field-replaceable lithium-ion batteries, each providing at least 3 hours of nominal operating time depending on usage conditions. The protective hard case, soft carrying bag and tool holster facilitate transport and on-site inspection.

FAQ – Frequently Asked Questions

What is the FOTRIC TD2e Kit used for?

The FOTRIC TD2e Kit is an acoustic imaging camera designed to locate compressed air leaks, pressurized gas leaks, vacuum leaks and abnormal acoustic emissions in industrial equipment.

What is the detection frequency range?

The camera operates across a 2–100 kHz frequency range, covering audible and ultrasonic frequencies.

What is the maximum working distance?

The manufacturer specifies a working distance of 0.3–60 metres. Actual detection performance depends on the leak characteristics, background noise and inspection conditions.

Can the TD2e Kit detect very small leaks?

The manufacturer reports detection sensitivity of 0.01 L/min under specific laboratory conditions. Actual performance varies with pressure, distance, leak size and environmental noise.

Can multiple leaks be identified simultaneously?

Yes. The Multi-source imaging mode allows the camera to visualize multiple acoustic sources within a single inspection scene.

Does the FOTRIC TD2e Kit measure temperature?

No. The TD2e Kit is an acoustic imaging camera, not a thermal imaging camera. Its acoustic heatmap indicates sound emissions rather than component temperatures.

Can it be used in noisy industrial environments?

Yes. Noise Suppression and manual frequency selection help technicians isolate relevant acoustic signals in challenging industrial environments.

Can the TD2e detect leaks through walls?

No. The camera detects airborne acoustic emissions. Solid barriers such as walls and soil can prevent sound from reaching its microphone array.

What is the difference between TD2e Standard and TD2e Kit?

Both versions use the same camera. The Kit adds a second rechargeable battery, a protective hard case, a soft carrying bag and an extended manufacturer-advertised warranty.

Can the TD2e Kit help reduce industrial energy costs?

Yes. Identifying compressed air leaks helps maintenance teams prioritize repairs and reduce avoidable losses. Actual savings depend on system pressure, operating hours, leak flow and compressor energy consumption.
