🚨 Introducing the NEW FLIR Si2a-Pro
Continuous Acoustic Monitoring for Partial Discharge AND Gas Leaks
Acoustic imaging just took another big step forward.
FLIR has launched the Si2a-Pro Industrial Fixed Acoustic Imaging Camera – bringing 24/7 partial discharge monitoring and pressurised gas leak detection together in one permanently installed solution.
✔ No waiting for the next inspection.
✔ No relying on a fault being present when an engineer happens to be there.
✔ The FLIR Si2a-Pro keeps listening around the clock.
FLIR Si2a-Pro – continuous acoustic monitoring, 24/7.
👀 What Happens Between Inspections?
Portable acoustic imaging has transformed condition monitoring.
Engineers can quickly scan electrical equipment for partial discharge or locate compressed air and gas leaks from a safe distance.
But every inspection is still a snapshot.
A developing electrical fault could appear days after an inspection. A compressed air leak could start overnight and continue wasting energy until the next survey.
The Si2a-Pro is designed to close that gap.
Installed permanently, it continuously monitors critical assets and uses acoustic imaging and automated analysis to identify developing problems.
⚡ Partial Discharge Monitoring – Around the Clock
Partial discharge can be an early warning of deteriorating electrical insulation.
The Si2a-Pro uses 124 low-noise MEMS microphones to detect and locate acoustic signatures associated with electrical faults. It can automatically recognise PD types including surface and internal discharge, positive and negative corona, and floating discharge.
It also provides automatic PRPD pattern recognition and AI-based severity assessment, helping maintenance teams understand not just where activity is occurring, but how seriously it should be treated.
Continuous acoustic monitoring can provide earlier visibility of developing electrical faults.
💨 And Now for the Big Difference: Gas Leak Detection
This is where the Si2a-Pro really stands out.
Alongside electrical monitoring, the same camera can continuously detect compressed air and pressurised gas leaks.
And it doesn't simply locate them.
The Si2a-Pro can automatically recognise leaks and estimate leak size and annual cost, helping maintenance teams understand which problems deserve attention first.
Leak-rate and cost quantification is available for gases including:
- Compressed air
- Ammonia
- Argon
- Carbon dioxide
- Helium
- Hydrogen
- Methane
- Natural gas
- Nitrogen
For manufacturing and industrial sites, that means one acoustic monitoring platform can help tackle electrical reliability and energy loss at the same time.
Find, locate and quantify pressurised gas leaks continuously.
🔎 One Device. Three Critical Applications.
The FLIR Si2a-Pro brings continuous acoustic monitoring to three critical areas across industrial and utility environments.
Compressed Air & Gas Leaks 
Detect and quantify compressed air and industrial gas leaks, including estimated leak size and annual cost. This helps reduce energy waste and prioritise repairs.
Industrial Partial Discharge 
Continuously detect, locate and assess partial discharge activity in critical electrical assets. This helps maintenance teams identify developing electrical problems earlier.
Utility Partial Discharge 
Continuously monitor transmission, distribution and substation assets for partial discharge activity associated with insulation faults and developing electrical problems.
One device. Three critical applications. 24/7 monitoring.
🧠 Intelligent, Connected Monitoring
Continuous monitoring is only useful if the information it produces can help maintenance teams make decisions.
The Si2a-Pro combines automated acoustic analysis with flexible connectivity to help turn acoustic data into useful maintenance information.
Intelligent analysis: Automatic recognition and AI-assisted severity assessment help identify and assess developing partial discharge activity.
Leak intelligence: Automatic leak recognition can provide estimated leak size and annual cost to help teams prioritise repairs.
24/7 visibility: Critical assets can be monitored continuously between routine inspections.
Connected monitoring: Integration options include REST API, MQTT, digital I/O and 4–20 mA connectivity.
🏭 Built for Industrial and Utility Environments
The Si2a-Pro isn't simply a portable acoustic camera mounted permanently.
It's designed as a fixed industrial monitoring solution.
With an IP66-rated enclosure, operating temperatures from -20°C to 50°C, PoE+ connectivity and an operating distance of up to 200 metres, it is designed for demanding industrial and utility applications.
Potential applications include electrical switchgear, substations, transmission and distribution assets, pipelines, valves, connections and plant-wide reliability programmes.
🔄 Portable Inspection + Permanent Monitoring
Does this mean portable acoustic imaging is going away?
Absolutely not.
Portable cameras remain ideal for routine surveys, troubleshooting and inspecting multiple assets around a site.
The Si2a-Pro adds something different:
Permanent eyes and ears on the assets that matter most.
Use portable acoustic imaging to survey the plant.
Use fixed acoustic imaging where you need continuous visibility.
🚀 The Next Step in Acoustic Imaging Has Arrived
For years, acoustic imaging has helped engineers find faults faster.
The FLIR Si2a-Pro takes that technology one step further by providing continuous acoustic monitoring across industrial electrical assets, utility infrastructure and compressed air and gas systems.
That means greater visibility of developing electrical problems alongside the ability to identify costly leaks and wasted energy.
At Acutest Direct, we're excited to introduce this new generation of fixed acoustic monitoring and help customers understand where it can deliver the greatest value.
