FLIR Si124 PD Acoustic Camera

Industrial Acoustic Imaging Camera

The FLIR Si124 acoustic imaging camera can help you locate pressurized leaks in compressed air systems or detect partial discharge from high-voltage electrical systems. This lightweight, one-handed solution can be used to identify issues up to 10 times faster than with traditional methods. Built with 124 microphones, the Si124 produces a precise acoustic image that visually displays ultrasonic information, even in loud industrial environments. The acoustic image is transposed in real time on top of a digital camera picture, which allows you to accurately pinpoint the source of the sound. Equipped with the FLIR Acoustic Camera Viewer cloud service, this smart tool automatically saves images to the cloud after they’re captured. Then you can access stored files and separate sound sources for deeper analysis and classification of problems. Through a regular maintenance routine, the FLIR Si124 can help facilities save money on utility bills and delay the expense of installing new compressors.
