The FLIR Si2-LD™ is an acoustic imaging camera that detects and quantifies pressurized air and gas leaks and identifies mechanical faults to reduce energy loss and prevent downtime.
The FLIR Si2-LD™ acoustic imaging camera for pressurized leak detection and mechanical fault enables you to detect and reduce leaks in facilities, thereby cutting costs associated with compressed air and specialty gas leaks. Beyond these capabilities, it also identifies mechanical faults, such as bearing issues, facilitating preventative maintenance to avoid downtime. The Si2 series delivers unparalleled performance, enhances decision support, simplifies fleet management, and integrates seamlessly with enterprise data, setting a new standard in its class.
Detect & Quantify Air and Gas Leaks
Automatically recognizes leaks, estimates leak size, and calculates annual cost to prioritize repairs and savings.
Mechanical Fault Detection Mode
Helps identify bearing faults and other mechanical issues early to support proactive maintenance.
Long-Distance Acoustic Imaging
Detects leaks and mechanical faults from up to 200 m (656 ft) away with real-time sound visualization.
Fast, One-Hand Inspections
Automatic tuning, 8× digital zoom, and a 12 MP camera make inspections quick and easy with minimal training.
Compressed Air Leak Detection (Industrial Facilities)
Locate and quantify leaks across manufacturing, production, and assembly environments.
Pressurized Industrial Gas Leak Detection
Identify leaks and estimate costs for common industrial gases to improve safety and reduce loss.
Mechanical Fault Detection (Bearings & Rotating Equipment)
Detect bearing issues early to plan repairs and avoid unplanned downtime.
Preventative Maintenance Programs
Improve inspection speed, reporting, and repair prioritization across large facilities.
