The FLIR Si2-Pro is ideal for routine inspections and preventive maintenance in demanding industrial environments, helping operators pinpoint hidden issues in bearings, compressed air systems, and electrical components before they lead to costly downtime.
Built for today’s industrial challenges, the Si2-Pro combines advanced detection capabilities with powerful software integration to help teams work faster, make confident decisions, and maintain critical assets more efficiently.
From on-site analysis to enterprise-level reporting, it streamlines the inspection process and supports a proactive approach to equipment health and energy savings.
In today’s industrial landscape, the smallest undetected fault can lead to massive losses in productivity, safety, and operational costs. The Teledyne FLIR Si2-Pro is built for that reality. It empowers maintenance teams, inspectors, and asset managers to see and hear what the human senses can’t, capturing detailed acoustic imagery that transforms invisible problems into actionable insights.
Whether it’s a barely audible gas leak, the early stages of electrical discharge, or a mechanical component on the brink of failure, the Si2-Pro delivers the clarity and confidence to act before issues escalate.
Electrical equipment often fails long before it completely breaks down, and one of the earliest warning signs is partial discharge—tiny sparks that silently erode insulation and components. The FLIR Si2-Pro detects these discharges at a scale thirty times smaller than older technology, revealing problems that would otherwise remain invisible.
On the other side of operations, a small air or gas leak can quietly bleed money every hour it goes unnoticed. By locating leaks five times smaller from four times the distance, the Si2-Pro not only spots the problem but also estimates the cost of wasted energy, helping teams prioritize repairs and savings.
Mechanical failures rarely happen overnight, they build up slowly through excess noise, vibration, or stress that the human ear can’t detect.
The FLIR Si2-Pro captures these subtle acoustic signatures across motors, pumps, gearboxes, conveyors, and bearings, identifying components that are beginning to wear down or run inefficiently.
Once a potential fault is identified, the camera’s AI-based severity assessment analyzes the data in real time, comparing it against known fault patterns using metrics like Sound Pressure Level (SPL), Crest factor, and Kurtosis.
The result is a clear severity rating displayed directly on the screen, along with recommended actions, so operators know whether to schedule maintenance, increase monitoring, or take immediate corrective measures.
Mechanical issues often hide in plain sight, but their sound patterns reveal the truth.
The FLIR Si2-Pro measures key acoustic metrics such as Sound Pressure Level (SPL), which shows how loud a fault is compared to healthy components, Crest Factor, which indicates whether a bearing needs lubrication or is starting to fail, and Kurtosis, which highlights abnormal signal patterns linked to wear or damage.
On the electrical side, partial discharge issues are visualized using a Phase-Resolved Partial Discharge (PRPD) pattern, a proven diagnostic tool that shows the type and severity of discharge occurring inside high-voltage equipment.
Instead of vague warnings, teams receive structured data and diagnostic insight that supports immediate action and long-term maintenance planning.
To make inspections easier to track and share, the camera also supports image annotations, allowing operators to tag snapshots with comments and context. This ensures that every detected issue is clearly documented for reports, teams, and follow-up maintenance.
Acoustic data is only useful if you can see it clearly. The FLIR Si2-Pro combines a 12-megapixel digital camera with a bright, 5-inch touchscreen display so operators can visualize issues in high detail as they happen.
The screen overlays acoustic imagery on real-world visuals, making it easy to spot the exact point of a leak, discharge, or fault.
Even in complex environments, the 1280 × 720 resolution and responsive controls give teams the confidence to make decisions on the spot without waiting for post-analysis.
Industrial environments are full of competing sounds, from humming machinery to air flow, which can make pinpointing a single issue feel like finding a needle in a haystack.
The FLIR Si2-Pro simplifies this with its automatic filter selection, which intelligently chooses the best frequency range and removes common industrial disturbances, leaving only the sounds that matter.
At the same time, the Auto Distance feature calculates how far the sound source is from the camera, adjusting the analysis to maintain accuracy.
Together, these tools take the guesswork out of inspections, giving operators clean data and precise measurements even in noisy, crowded facilities.
The FLIR Si2-Pro doesn’t just detect problems, it connects them to your workflow. With cloud integration, every snapshot and video can be uploaded automatically to the FLIR Acoustic Camera Viewer, giving teams unlimited storage and instant access from anywhere.
For larger operations, fleet management tools make it simple to oversee multiple cameras, standardize reporting, and push over-the-air updates, ensuring your entire team is always working with the latest features. By centralizing data and making it easy to share across departments, the Si2-Pro helps organizations move from reactive repairs to proactive maintenance strategies.
