Flir Si2-Pro™
Industrial Acoustic Imaging Camera for Partial Discharge Detection, Pressurized Leak Detection and Mechanical Fault Detection
The Flir Si2-Pro helps you significantly lower costs associated with mechanical bearing issues and partial discharge on electrical equipment. It also enables you to drastically reduce leaks in your facilities, cutting down expenses related to compressed air and gas leaks. With the Si2 series, you'll experience the best-in-class performance, decision support, fleet management, and enterprise data integration available.
For specialized needs, you can choose from additional models: opt for the Si2-LD for advanced leak detection and mechanical fault detection applications or select the Si2-PD for your electric utility applications. Explore these models in the related products section below to find the perfect fit for your requirements.
Clear Vision, Sound Solutions
Precisely detect, locate, and measure compressed air leaks, gas leaks, and partial discharges. Identify and quantify both minor and elusive issues from up to 200 m (656 ft) away—boosting operational efficiency and ensuring safety.
Save on costly repairs, reduce downtime, and enhance maintenance efficiency by identifying bearing defects before they 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.
