- Usually ships in 3 business days
Description
The FLIR Si2-Pro Acoustic Imaging Camera is FLIR's full-capability acoustic imaging camera, combining pressurized leak detection, partial discharge detection, and mechanical fault detection in one instrument.
The 124-microphone array covers leaks, electrical discharge, and bearing/mechanical signatures with AI-based severity assessment, leak-rate and cost quantification, and discharge pattern analysis. With FLIR Ignite™ reporting and a rugged industrial housing, the Si2-Pro is the single acoustic camera for plant and utility reliability programs.
- Three-in-one inspection tool: partial discharge detection, pressurized leak detection and mechanical fault detection
- 124 low-noise MEMS microphones; detect, locate and measure from 0.3 m up to 200 m (656 ft)
- Leak rate detection threshold: 0.0032 l/min from 2.5 m, 0.0044 l/min from 6 m
- Quantifies leak-rate costs for compressed air, ammonia, argon, CO2, helium, hydrogen, methane, natural gas and nitrogen
- Automatic AI-based PD severity assessment with recommended actions
- Mechanical fault detection helps cut bearing-issue costs before failure
- Best-in-class performance with decision support, fleet management and enterprise data integration
- Cloud integration, OTA updates, and combined acoustic + thermal reporting
Typical Applications
- Compressed air and gas leak surveys
- Partial discharge detection
- Predictive maintenance
- Energy loss audits
