FLIR Si2x-Pro Industrial Acoustic Imaging Camera

The FLIR Si2x-Pro Acoustic Imaging Camera is specifically engineered for use in hazardous gas and explosive dust environments, where safety and reliability are critical. Now upgraded with IECEx Zone 2 certification for gas, in addition to the existing ATEX Zone 2/22 certification for dust and gas, the Si2x-Pro meets internationally recognized safety standards, ensuring compliance across global operations. This next-generation acoustic imager is designed to help industries detect and quantify pressurized gas leaks, identify mechanical faults, and monitor partial discharge in electrical equipment with unmatched accuracy. By combining best-in-class acoustic imaging performance, AI-driven analysis tools, and real-time leak quantification, the Si2x-Pro not only enhances worker safety but also helps organizations minimize energy losses, reduce downtime, and lower maintenance costs. With integrated fleet management, cloud-based data reporting, and seamless enterprise-level integration, the Si2x-Pro empowers teams to operate with confidence and efficiency, even in the most demanding explosive atmospheres.

For applications that don’t require partial discharge detection, the Si2x-LD is an ideal option for leak and mechanical fault detection.

FLIR Si2x-Pro Key Features

Si2x Leak Detection

Advanced Leak and Partial Discharge Detection

Accurately detect, locate, and measure compressed air leaks, gas leaks, and partial discharges. Identify and quantify even small or hard-to-find issues from distances of up to 200 meters (656 feet), improving operational efficiency and enhancing safety.

Si2x maintenance

Mechanical Fault Analysis

Reduce costly repairs, minimize downtime, and improve maintenance efficiency by detecting bearing and other mechanical defects early, before they lead to overheating or equipment failure.

Si2x reporting

Fleet Management Functionality

Maximize equipment utilization and maintenance efficiency in large-scale industrial environments with fleet management, cloud data integration, and over-the-air (OTA) software updates. Consolidate acoustic and thermal imaging data into a single report for comprehensive analysis.

Why Choose the FLIR Si2x?
