FLIR Si-Series Acoustic Imaging Cameras

Compressed air leaks, specialized gas leaks, mechanical faults, and electrical partial discharges are all expensive system issues that consume power, leaving your company to deal with unforeseen costs and potential production/uptime issues. Ultrasonic imaging with an acoustic camera is an effective way to detect these equipment issues as part of a complete asset management plan. The FLIR Si-Series is your perfect solution for locating compromised areas in your compressed air systems, and for identifying partial discharge problems in high-voltage electrical systems. This lightweight, one-handed detector can help you in utility, manufacturing, and engineering applications to identify efficiency loss and potential failures up to 10 times faster than traditional methods—with minimal training.

Compressed air leak detection

Finding the source of an air leak can be difficult and time-consuming with most tools, but our intelligent ultrasonic imaging detection equipment can make it quick and easy. FLIR Si-Series cameras provide leak rates and cost estimations at safe distances to help with leak detection and prioritize repairs to improve safety and save money.

Detect Mechanical Faults

The Si2's MECH mode detects and measures the severity of bearing faults and other mechanical issues, before they lead to costly production disruption or safety hazards.

Detect Partial Discharge

Partial discharge (PD) indicates partial failure of an electrical insulator (can be a mechanical insulator, air gap, vacuum, liquid, etc.). Si-Series models use artificial intelligence to classify the specific type of partial discharge so you know exactly what to fix: surface discharge (typical with insulators, bushings, terminations), floating discharge (between components), and corona.

What To Look for In An Acoustic Imager

Effective Frequency Range

To ensure you’re choosing the right equipment, take a critical look at your camera’s frequency range. You might think that you need the widest range possible in order to pick up the widest range of sounds. However, in reality, the most effective frequency range for compressed air leak detection is between 20 and 30 kHz. This is because using the 20 to 30 kHz range aids in distinguishing compressed air leaks from the background noise in a factory.

Optimal Number of Microphones

In the pursuit of quieter noises, more is better. Acoustic imaging cameras typically employ dozens of micro-electric-mechanical system (MEMS) microphones to collect and characterize sound. While MEMS are small, use little power, and are very stable, they also generate their own noise that interferes with an individual microphone's ability to pick up very quiet sounds. The solution is to increase the number of microphones in use; simply doubling the number of microphones improves the signal-to-noise ratio enough to remove three decibels of unwanted sounds.

FLIR Thermal Studio Compatibility

The FLIR Si-Series Plugin for FLIR Thermal Studio allows you to import images from FLIR Si-Series acoustic imagers to FLIR Thermal Studio. Easily edit and analyze images, and create advanced reports. With the plugin, you have support for automatic fault classification, severity indication, recommended action for utility inspections, estimation of leak volume, and cost savings for air leaks. Combine acoustic images with thermal imaging from FLIR handheld infrared detectors such as the FLIR E8 Pro for water leak detection in the same report.
