FLIR Si2 Advanced Industrial Acoustic Camera Range

The FLIR Si2 range is a family of advanced industrial acoustic imaging cameras designed to detect and analyse partial discharge (PD) faults, compressed‑air and industrial gas leaks, and mechanical issues such as bearing faults, combining long‑range ultrasonic detection (up to 200m) with AI‑based severity assessment, 12 MP visual imaging, 8× zoom, and automatic frequency tuning.

Models across the range such as the Si2‑LD, Si2‑PD, and Si2‑Pro feature wide acoustic bandwidths (2–130 kHz), support for multiple gases, real‑time leak cost quantification, and integration with FLIR Acoustic Camera Viewer and Thermal Studio for cloud and desktop reporting, making them suitable for predictive maintenance, electrical reliability assessments, and comprehensive facility diagnostics.
