Identifying and resolving system issues like compressed air leaks, vacuum system leaks, and electrical partial discharge is crucial for minimizing costs and avoiding production interruptions. Ultrasound imaging using an acoustic camera is a reliable method for detecting these equipment issues as part of a comprehensive asset management strategy. The FLIR Si-Series offers an ideal solution for pinpointing pressurized leaks in compressed air systems and identifying partial discharge problems in high-voltage electrical systems. This lightweight, one-handed camera is suitable for utility, manufacturing, and engineering applications, enabling users to identify efficiency loss and potential failures up to 10 times faster than traditional methods, with minimal training required.

Key Advantages of Acoustic Imaging
Compressed Air Leak Detection
Locating the origin of an air leak can often be a challenging and time-consuming task using conventional tools. However, our advanced ultrasonic imaging system simplifies this process, making it both quick and efficient. FLIR Si-Series cameras offer precise leak rates and cost estimations from safe distances, facilitating leak detection and enabling prioritized repairs to enhance safety measures and cost savings.
Detect Mechanical Faults
The Si2's MECH mode is designed to identify and measure the severity of bearing and other mechanical issues, preventing them from causing expensive production disruptions or safety risks.
Detect Partial Discharge
Partial discharge (PD) signals a partial breakdown in an electrical insulator, which can occur in various mediums such as mechanical insulators, air gaps, vacuum, or liquids. Si-Series models utilize artificial intelligence to categorize the type of partial discharge, enabling precise identification of issues for targeted solutions. These classifications include surface discharge (common with insulators, bushings, and terminations), floating discharge (between components), and corona.
Why Choose a FLIR Acoustic Imager?
Effortless one-hand operation
You can keep one hand free while inspecting components for operator safety and to reduce neck strain.
Superior sound detection with 124 microphones
Si-Series cameras are equipped with 124 microphones, enabling the detection of extremely faint noises over long distances for ultrasonic imaging. This feature is particularly crucial when examining high-voltage systems and potential leaks, necessitating a safe distance from energized equipment. As sound signals lose intensity with distance, increasing the number of microphones extends the sound detection range. Quadrupling the microphones effectively doubles this range. The cameras utilize optimized dynamic range to strike a balance between frequency capabilities and sound propagation distance. Employing lower frequencies maximizes detection distance.
Enterprise Scalability
Maximize the utilization and upkeep of equipment within extensive industrial operations through fleet management, cloud data integration, and Over-The-Air (OTA) software updates. Accompanying software offers integration with data historians, cloud-based and desktop reporting options, as well as the merging of IR and acoustic inspection programs. Si-Series users can leverage the Organization feature, a user-friendly solution that streamlines reporting follow-ups across multiple locations and users.
Machine learning capabilities
The FLIR Si-Series employs machine learning to differentiate between the distinct characteristics of sound patterns produced by leaks and partial discharge (PD) from background noise. This process is akin to discerning between the sounds of a harmonica and a bell playing the same note. With a multitude of sensitive microphones and advanced computer processing utilizing machine learning, we can accurately distinguish between background noise and defect-induced noise based on properties beyond frequency.

What to Look for in an Acoustic Imaging Camera
Effective Frequency Range
One of the first features to consider is the 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.
