Industrial Acoustic Imaging Camera for Compressed Air Leak Detection

FLIR Si124-LD Plus

Go to Product Support
product image

The FLIR Si124-LD Plus is an easy-to-use, stand-alone system for locating and quantifying pressurized leaks in compressed air systems. This lightweight, one-handed solution is designed to help maintenance, manufacturing, and engineering professionals identify air leaks up to 10 times faster than with traditional methods. Built with 124 microphones, the Si124-LD Plus produces a precise acoustic image that visually displays ultrasonic information, even in loud, industrial environments. The acoustic image is overlaid in real time on a digital camera picture, allowing you to accurately pinpoint the source of the sound. The Si124-LD Plus features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Through a regular maintenance routine, the FLIR Si124-LD Plus can help facilities save money on utility bills and delay the expense of installing new compressors.

Available in additional models which include: the Si124-PD for electric utility applications, or the Si124 for both electric utility and leak-detection applications. View the models in the related products section below.

  • Accurately find the smallest leaks

    Accurately detect and measure small compressed air and gas leaks (from 0.016 l/min to 0.004 l/min) up to 10 times faster with sound imaging, Auto Distance, and Auto Filtering features

  • Reduce costs, save money

    Minimize excess utility costs, equipment failures, and downtime by ensuring proper air pressure to pneumatic equipment and quantifying leak size to understand how much energy was lost

  • Inspect easily

    Quantify leak severity in real time with this lightweight, smart tool that you can operate with one hand and minimal training

Auto Filter

On most acoustic cameras, you have to manually select the frequency range. Auto Filter automatically chooses the correct settings for each environment and automatically filters out disturbances to make operation even simpler and more effective at finding leaks.

Auto Distance

To get the most accurate leak size estimates, the approximate distance to the leak must be calculated. Auto Distance* automatically detects the distance between the leak and your camera to improve accuracy and reduce manual inputs.

*AutoDistance works for distances up to 5 meters (16 feet)

Continuous Auto-Correct

Improves leak detection performance to find even smaller air leaks from 0.016 l/min to 0.004 l/min.
