Comprehensive Condition Monitoring with SonaVu™ Acoustic Imaging Cameras

Introduction

In the world of industrial maintenance, unseen faults can quietly erode efficiency, compromise safety, and inflate operational costs. The SonaVu™ series by SDT Ultrasound Solutions is changing that reality.
Through advanced acoustic imaging technology, SonaVu™ detects and visualises hidden issues across mechanical, electrical, and pneumatic systems — before they escalate.

As the trusted distributor of SDT Ultrasound Solutions in Sub-Saharan Africa, Piezo-SA brings this cutting-edge innovation to local industries, empowering maintenance teams to achieve lasting reliability and energy efficiency.

🔹 Vacuum Leak Detection

Vacuum systems play a vital role in many industrial processes. Even a small leak can compromise product quality or reduce system performance. Traditional methods often fall short — vacuum leaks draw air in, making them notoriously difficult to trace.
With SonaVu™, these invisible issues become instantly audible and visible. The system captures ultrasound data and transforms it into a clear, real-time image, allowing technicians to locate and repair leaks quickly.

Key Benefits:

Early detection of vacuum leaks
Prevention of product contamination
Reduced energy consumption

🔹 Fugitive Emissions Detection

Fugitive emissions — unintentional gas leaks from valves, fittings, and pipelines — threaten both safety and compliance. For sectors such as petrochemical, oil and gas, and pharmaceuticals, effective detection is non-negotiable. SonaVu™ detects the high-frequency ultrasound generated by escaping gases, enabling safe, non-invasive identification of leaks without the need for shutdowns or intrusive testing.

Key Benefits:

Enhanced safety and regulatory compliance
Reduced environmental impact
Cost-effective and efficient detection

🔹 Compressed Air Leak Management

Compressed air is one of the most expensive utilities in any plant, yet up to 30% of energy can be lost through undetected leaks. SonaVu™ provides a precise, non-invasive way to find and visualise these losses, even in noisy production environments. By locating and repairing leaks early, facilities can save significant energy and operating costs.

Key Benefits:

Identification of hidden air leaks
Reduced energy waste
Improved system efficiency

🔹 Mechanical Fault Detection

Mechanical components, bearings, chains, belts, and drives, naturally wear over time. However, traditional inspection methods often detect issues only after failure begins. SonaVu™ changes that. It captures ultrasound data generated by friction, impact, or misalignment and overlays it onto a real-time visual image. This allows maintenance teams to see the health of mechanical assets at a glance and act before costly breakdowns occur.

Key Benefits:

Early identification of mechanical issues
Prevention of unexpected downtime
Extended equipment lifespan

🔹 Electrical Fault Detection

Arcing, tracking, and corona discharge often appear long before heat or visible damage is detected — but these early signs are usually inaudible to the human ear. SonaVu™’s acoustic imaging camera captures the high-frequency signals associated with these faults, allowing maintenance teams to locate and assess issues safely from a distance.

Key Benefits:

Early detection of electrical defects
Improved plant safety
Reduced risk of catastrophic failure

How SonaVu™ Works

SonaVu™ combines ultrasound sensing with real-time visualisation, transforming invisible sound data into a clear acoustic image.
Using the InSights™ app, technicians can record, analyse, and share findings seamlessly, creating a data-driven approach to predictive maintenance.

Whether monitoring compressed air, detecting fugitive emissions, or diagnosing electrical faults, the system brings clarity to complex maintenance challenges.

🔹 SonaVu™ Series Overview
