FLIR T912340 Si2-Pro Professional Acoustic Imaging Camera MECH and PD Detection

The FLIR T912340 Si2‑Pro, is a professional industrial acoustic imaging camera designed for comprehensive diagnostic work across electrical systems, compressed air/gas infrastructures, and rotating machinery. It integrates long distance ultrasonic detection with AI‑based severity assessment, making it suitable for large scale predictive maintenance programs.

Primary functions include detect, locate, classify, and assess partial discharge (PD) faults up to 200m (656ft) away, detect and quantify compressed air and industrial gas leaks, including cost estimation, and identify mechanical faults such as bearing issues using MECH mode.

Partial Discharge Detection

• Detects and classifies PD types (e.g., corona, surface, internal)
