FLIR Unveils Si2-Series Acoustic Imagers for Leak, Discharge, Fault Detection

A Teledyne Technologies company, FLIR, announced the expansion of the Si-Series acoustic imaging cameras with three models in the Si2 portfolio, designed for detecting compressed air leaks, specialty gas leaks, mechanical faults, and partial discharges. The Si2-Pro, Si2-LD, and Si2-PD offer industrial-grade solutions for the detection of air and gas leaks, as well as faults such as bearing issues, for industries including manufacturing, electrical, and utilities.

FLIR’s Si2-Series cameras provided elevated performance, with the ability to identify issues over long distances, detect and measure with increased sensitivity, and produce more accurate classification of issues. The Si2-Series features improvements in acoustic camera picture, including a 12 MP color camera, 8x digital zoom, and LED illumination for managing dark areas. They also have increased battery life to keep professionals in the field without the need for swapping power sources.

Specialty gas leak quantification and cost estimates have been expanded beyond compressed air to include common industrial gases such as hydrogen, CO₂, methane, helium, argon, ammonia, and more.

• FLIR Si2-Pro: Industrial acoustic imaging camera for pressurized leak detection, mechanical fault detection, and partial discharge detection with on-camera severity assessments.
• FLIR Si2-LD: Industrial acoustic imaging camera for pressurized leak detection and mechanical fault detection in manufacturing and other industrial environments.
• FLIR Si2-PD: Industrial acoustic imaging camera for partial discharge detection with on-camera severity assessments for power infrastructure inspection.

FLIR’s advanced automatic filtering identifies leaks by sound signatures even in noisy industrial environments. A new “mech mode” feature in the Si2-Series enhances site safety by allowing quick detection of mechanical issues, enabling professionals to rapidly evaluate conditions, identify problems, and implement solutions. Plant operators can identify mechanical, leak, and partial discharge issues, then generate reports for immediate attention. The on-camera decision support tools include mechanical defect measurement, classification and severity assessment of partial discharges, leak size estimation, and cost analysis.

The Si2-Pro combines the features of the Si2-LD and Si2-PD, lowering costs by addressing mechanical bearing issues and partial discharge on electrical equipment. It also significantly cuts leaks in facilities to reduce expenses from compressed air and gas leaks. FLIR provides its acoustic training platform and 24/7 support through its global service organization.
