Enhancing Predictive Maintenance with Fotric TD2e Acoustic Imaging
Acoustic imaging cameras such as the Fotric TD2e represent a practical, field-ready solution for rapid fault detection in industrial and electrical environments. The TD2e utilises a 64-microphone MEMS array combined with a visual camera to generate real-time acoustic images, enabling users to “see” ultrasonic sound sources such as compressed air leaks or partial discharge. With a wide frequency range of 2 kHz to 100 kHz and detection distances up to 60 m, the device can identify both audible and ultrasonic anomalies that are otherwise undetectable using conventional methods .
From an application perspective, the TD2e is particularly suited for compressed air leak detection, gas leak localisation, and electrical discharge identification (corona, tracking, arcing). Its built in noise suppression mode ensures reliable operation even in high noise industrial environments, while micro detection capability allows capture of very subtle fault signatures . This makes it effective for routine inspections, predictive maintenance programs, and energy efficiency audits.

In utility and asset intensive industries, the TD2e supports a shift toward condition-based maintenance, reducing downtime and inspection effort. Compared to traditional techniques such as soapy water testing or handheld ultrasonic probes, it offers non contact, fast, and visual fault localisation, significantly improving maintenance productivity and safety.
Dual Detection Mode
a. Noise Suppression Mode: Maintains stable acoustic imaging even in high-noise environments, accurately locating true sound sources.

b. Micro-Detection Mode: Captures subtle sounds, ensuring no potential issue points are missed.
