- Usually ships in 3 business days
Description
The FLIR Si2-PD Acoustic Imaging Camera is an industrial acoustic imaging camera for partial discharge detection on high-voltage equipment, helping utilities and plants find insulation failures before they flash over.
Its 124-microphone array detects corona, surface, and floating discharge from up to 656 ft (200 m), with automatic AI-based severity assessment and recommended actions, plus PRPD pattern analysis in FLIR software. On-screen results and cloud reporting turn substation walks into documented, prioritized findings.
- 124 low-noise MEMS microphones detect, locate, classify and assess partial discharge faults from up to 200 m (656 ft)
- Detects PD issues 30x smaller than previously possible
- Automatic AI-based severity assessment with recommended actions, on camera and in software
- Fleet management tools for large-scale utility inspection programs
- Cloud data integration and automatic over-the-air (OTA) software updates
- Combine acoustic and thermal imaging in the same report
- One-handed, lightweight design with 12 MP digital camera and 8x zoom
- 5-inch 1280 × 720 touchscreen for fast field assessments
Typical Applications
- Compressed air and gas leak surveys
- Partial discharge detection
- Predictive maintenance
- Energy loss audits
