FLIR Si2x-Pro Hazardous Location Acoustic Imaging Camera

Key Features:

Hazardous Area Certification (ATEX & IECEx) for Gas & Dust Zones
Certified for Zone 2 explosive gas atmospheres and Zone 22 dust environments. Designed for safe operation in hazardous locations. 

Advanced Leak, Mechanical Fault & Partial Discharge Detection
All-in-one device: detects, locates, and measures compressed air/gas leaks, bearing or mechanical faults, and partial discharges. 

High Sensitivity Acoustic Measurement System
124 low-noise MEMS microphones, with real-time sound visualization over bandwidth of 2-130 kHz, allowing detection of subtle ultrasonic signals in noisy industrial environments. 

Long Detection Range & Fine Leak Rate Sensitivity
Operates from ~0.3 m (1 ft) up to 200 m (656 ft); Minimum detectable leak rate: 0.0032 L/min at 2.5 m, 0.0044 L/min at 6 m. 

High-Resolution Imaging & Visual Context
12 MP colour camera, 75° diagonal field of view, 8× digital zoom, with built-in LED lights for low-light conditions; overlay of acoustic sound map on visual image to pinpoint issues. 

Automatic AI-Based Diagnostics & Severity Assessment
On-camera and in-software partial discharge type classification and severity scoring, plus mechanical condition assessment via metrics like sound pressure level, crest factor etc., enabling pre-emptive maintenance. 

Fleet Management & Enterprise Integration
Supports Over-The-Air (OTA) firmware/software updates, cloud data transfers (WiFi dual band 2.4 & 5 GHz), compatibility with FLIR Thermal Studio and Acoustic Viewer, facilitating reporting, data centralization and fleet health tracking.

Robust Design & Usability in Harsh Environments
IP54 ingress protection; operates from −10 °C to 50 °C; compact design with durable housing; large resistive touch display (5-inch, 1280×720) & intuitive UI to reduce training requirement. 

Measurement & Cost-Saving Analytics
Quantifies leak rates and estimates financial losses (gas/compressed air leaks), allowing priority setting of repair work and supporting energy efficiency / ESG objectives. 

Wide Gas Compatibility
Detects leaks of multiple industrial gases: compressed air, nitrogen, ammonia, hydrogen, carbon dioxide, methane, helium, argon, etc.
