FLIR Si2a-Pro Leak and Partial Discharge Fixed Acoustic Imaging Camera (with Wi-Fi)
The FLIR Si2a-Pro Leak and Partial Discharge Fixed Acoustic Imaging Camera (with Wi-Fi) is designed for continuous monitoring of compressed air and gas leaks and partial discharge (PD) activity. Instead of relying solely on scheduled inspections, it provides 24/7 acoustic monitoring of critical equipment, helping maintenance teams spot developing problems earlier and respond before they lead to unnecessary energy loss, equipment damage or downtime.
Equipped with 124 low-noise MEMS microphones and a 2 kHz to 130 kHz frequency bandwidth, the Si2a-Pro can detect, locate and evaluate acoustic events across a wide range of industrial applications. It offers directional resolution from 1° down to 0.125° and can monitor targets at distances ranging from 0.3 m to 200 m.
Continuous Leak Detection
The Si2a-Pro continuously monitors for pressurised gas leaks, as well as estimate leak rates and calculate the associated financial impact, allowing maintenance teams to prioritise repairs based on severity and cost.
The system is capable of detecting a variety of gases under sufficient pressure, including:
- Compressed air
- Ammonia
- Argon
- Carbon dioxide
- Helium
- Hydrogen
- Methane
- Natural gas
- Nitrogen
With continuous monitoring, leaks can be identified as they develop rather than waiting for scheduled inspections, improving operational efficiency and reducing unnecessary losses.
Partial Discharge Monitoring
In addition to leak detection, the Si2a-Pro provides continuous monitoring of partial discharge activity in electrical infrastructure. It helps identify insulation defects and developing electrical faults in transmission and distribution equipment, substations, switchgear and gas-insulated assets.
By continuously monitoring acoustic emissions, the camera can capture intermittent partial discharge events that may be missed during routine inspections. This supports earlier fault detection, improves maintenance planning and helps reduce the risk of equipment failure and unexpected outages.
Visual Verification
While the Si2a-Pro continuously detects and analyses acoustic events, its integrated visual imaging capabilities provide valuable context for verification and investigation. Operators can quickly correlate detected leaks or partial discharge activity with the physical asset, helping accelerate diagnosis and corrective action.
The camera incorporates a 12 MP colour digital camera with a 75° diagonal field of view, supporting 960 × 540 video streaming at 15 fps and snapshot capture at 30 fps. Real-time sound visualisation overlays acoustic data onto the visual image, making it easier to locate, assess and document detected events.
Intelligent Monitoring, Wireless Connectivity and Integration
Built-in AI-driven analysis helps process and classify detected acoustic events in real time, reducing the amount of manual input required from operators. Configurable monitoring zones and alarm thresholds support unattended operation, ensuring personnel are alerted when abnormal conditions are detected.
This version also provides wireless connectivity through built-in Wi-Fi, supporting both 2.4 GHz and 5 GHz networks with IEEE 802.11 b/g/n/ac compatibility. A Wi-Fi antenna is included, providing a convenient wireless connection for installations where network connectivity is required without relying solely on a wired connection.
For enterprise-wide condition monitoring, the camera is compatible with FLIR AssetLink™, allowing data and alerts to be integrated into centralised asset management and maintenance workflows. This combination of AI-driven analytics, wireless connectivity and system integration makes the Si2a-Pro an effective solution for organisations looking to scale continuous monitoring across multiple assets and sites.
Built for Permanent Installation
Designed for demanding industrial and utility environments, the Si2a-Pro features a rugged IP66-rated enclosure that provides protection against dust and water ingress. Its low-maintenance design and flexible mounting options make it well suited to permanent installations where dependable, long-term monitoring is essential.
Main Applications
Typical applications for the Si2a-Pro include:
- Continuous monitoring of transmission, distribution and substation assets to detect insulation faults and reduce the risk of power outages.
- Detection of compressed air and industrial gas leaks across pipelines, valves and connections to minimise energy losses, operating costs and emissions.
- Condition monitoring of switchgear and gas-insulated equipment to identify both electrical and gas-related issues at an early stage.
- Remote monitoring applications where Wi-Fi connectivity enables easier deployment and access to real-time condition data.
- Plant-wide reliability improvement by combining leak detection and partial discharge monitoring in a single continuous monitoring solution.
