FLIR Si2x-LD™

Hazardous Location Acoustic Imaging Camera for Pressurized Leak Detection and Mechanical Fault Detection

The Si2x-LD Acoustic Imaging Camera is specifically designed for use in hazardous gas and explosive dust environments, to easily reduce leaks of toxic or flammable gases to improve safety, or cut expenses associated with compressed air or gas leaks in your facilities. With its advanced analysis tools, the Si2x-LD provides a robust solution for lowering costs associated with mechanical bearing issues. Engineered for hazardous operations, it offers best-in-class performance, decision support, and fleet management, along with enterprise data integration for optimal efficiency and safety.

For those requiring partial discharge detection, you can opt for the Si2x-Pro for PD, leak. and mechanical fault detection.

Whether it’s a small hiss or a hard-to-find leak, this camera can identify and quantify compressed air and specific gas leaks from up to 200 m (656 ft) away, making it indispensable for ensuring operational efficiency and safety.

Save on costly repairs, reduce downtime, and enhance maintenance efficiency by identifying bearing and other mechanical defects before they overheat or cause equipment failure.

Ensure optimal use and maintenance of equipment in large-scale industrial settings with fleet management, cloud data integration, and OTA software updates. Combine acoustic and thermal imaging in the same report.
