The FLIR Si2a-Pro combines partial discharge detection and leak detection in one fixed acoustic imaging camera. It helps teams identify PD activity, corona, arcing, compressed air leaks and industrial gas leaks earlier — supporting safer diagnostics, reduced downtime and improved plant reliability.
DETECT ELECTRICAL FAULTS AND LEAKS BEFORE THEY BECOME COSTLY
Continuous fixed acoustic monitoring for partial discharge, compressed air leaks and pressurised gas leaks.
DUAL ACOUSTIC MONITORING
Built for electrical faults and leak-related losses.
The FLIR Si2a-Pro supports continuous monitoring across electrical and industrial assets — helping teams detect partial discharge activity, compressed air leaks and pressurised gas leaks before they become downtime, safety risks or unnecessary operating costs.

WHY IT MATTERS
Smarter monitoring. Safer decisions. Lower losses.
Continuous acoustic monitoring helps maintenance teams detect risk earlier, reduce manual inspection pressure and respond with confidence across both electrical and leak detection applications.
One Camera. Two Critical Risks.
Monitor both partial discharge and pressurised gas leaks with a single fixed acoustic imaging camera.
Find Faults and Losses Earlier
Detect PD activity, compressed air leaks and gas leaks before they become outages, safety risks or costly waste.
AI Turns Signals Into Action
AI-driven analysis helps classify faults, assess severity, estimate leak impact and support faster decisions.

DETECT ELECTRICAL FAULTS AND LEAKS BEFORE THEY BECOME COSTLY
Partial discharge, corona, arcing and pressurised gas leaks can be intermittent and difficult to capture during scheduled inspections. The FLIR Si2a-Pro provides continuous acoustic monitoring so developing electrical faults and leak-related losses can be detected, assessed and prioritised earlier.
By combining electrical fault detection and leak detection in one fixed acoustic solution, the Si2a-Pro helps teams reduce risk, improve safety and identify costly losses before they escalate.
