Flir Si2 Pro Acoustic Imaging Camera is an advanced, handheld industrial acoustic imaging camera designed to detect partial discharges, pressurized gas/vacuum leaks, and mechanical bearing faults.
The Flir Si2 Pro Acoustic Imaging Camera 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.
Flir Si2 Pro Acoustic Imaging Camera Features
- Advanced Leak Detection: 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.
- Bearing Fault Analysis: Save on costly repairs, reduce downtime, and enhance maintenance efficiency by identifying bearing defects before they cause equipment failure.
- Fleet Management Functionality: 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.
