Fixed acoustic imaging cameras for continuous asset condition monitoring

Teledyne FLIR’s Si2a-LD and Si2a-Pro now complete the new Si2a-Series portfolio of fixed-mount acoustic imaging solutions for continuous condition monitoring in industrial and utility environments.

Designed to provide always-on visibility into asset health, the Si2a-LD and Si2a-Pro help organisations move beyond periodic inspections by continuously monitoring critical systems for developing issues. Integrated with the FLIR AssetLink ecosystem, both solutions support proactive maintenance strategies by helping teams identify problems earlier, reduce manual inspection effort, and make more informed maintenance decisions.

The Si2a-LD is purpose-built for continuous monitoring of compressed air and gas leaks, helping organisations reduce energy waste and operating costs. The Si2a-Pro expands monitoring capabilities further by combining continuous leak detection with partial discharge monitoring, providing broader insight into asset condition through a single fixed-mount solution.

Compressed air and gas leaks are among the most common sources of energy waste in industrial facilities, while intermittent faults often go undetected between scheduled inspections. The Si2a-Series helps address these challenges by continuously monitoring critical assets and alerting teams to developing issues as they occur.

Key benefits

• Always-on acoustic monitoring for critical assets and systems
•  Detect compressed air and gas leaks early to reduce energy loss and operating costs
• Capture intermittent faults and events that periodic inspections often miss
• AI-enhanced detection and classification for faster, more confident decisions
•  Configurable monitoring zones and alarms for unattended operation
• Improve reliability with earlier visibility into developing issues
• Reduce manual inspection effort through continuous condition monitoring
• Integrate with AssetLink and enterprise systems for centralised workflows
• Designed for permanent deployment in industrial and utility environments
•  Low-maintenance, scalable architecture for monitoring across multiple sites

By combining continuous acoustic monitoring with AI-enhanced analysis and AssetLink integration, the Si2a-LD and Si2a-Pro help organisations identify issues earlier, improve reliability, and make more informed maintenance decisions. As part of the broader FLIR condition monitoring portfolio, these solutions can also be used alongside handheld acoustic imaging cameras, handheld thermal cameras, and fixed thermal monitoring solutions to provide a more comprehensive view of asset health and support proactive maintenance strategies across critical infrastructure and industrial operations.
