FLIR Si2a-PD Industrial Fixed Acoustic Imaging Camera
- Detect Partial Discharge Before It Causes Downtime
The FLIR Si2a-PD is an advanced Fixed Acoustic Imaging solution designed for continuous monitoring of electrical assets. It helps maintenance teams detect partial discharge (PD), corona, arcing, and other electrical faults early, reducing the risk of unplanned outages and costly repairs.
Unlike handheld inspection tools, the FLIR Si2a-PD provides 24/7 monitoring, giving you constant visibility of asset condition. This intelligent Fixed Acoustic Camera combines acoustic imaging, AI-powered analysis, and remote connectivity to support predictive maintenance programmes across industrial and utility environments.
