FLIR Si2-LD Industrial Acoustic Imager – Leak Detection

The FLIR Si2-LD Industrial Acoustic Imager is a simple-to-use, highly sensitive sonic imager optimised for leak detection and mechanical fault identification. It builds on the capabilities of the FLIR Si124-LD Industrial Acoustic Imager and as such can detect leaks that are 5x smaller from 4x the distance. For example, the FLIR Si2-LD Industrial Acoustic Imager can locate compressed air/gas leaks from up to 200m (656 ft) from the source. Moreover, a measurement and cost analysis function for industrial gas leaks (ammonia, hydrogen, carbon dioxide, methane, helium, and argon) makes assessing and prioritising repairs easy and efficient. Similarly, a Mechanical Fault mode, which automatically selects and optimises filters, enables fast, simple mechanical/bearing fault identification. In addition to this, the FLIR Si2-LD Industrial Acoustic Imager includes several new features including a 12MP digital camera; 8x digital zoom; 1280 x 720px, 5-inch colour screen; built-in LED lights; and Fleet Management functionality. The FLIR Si2-LD Industrial Acoustic Imager sets a new standard in its class. This ergonomic, easy-to-use, efficient ultrasonic camera delivers unparalleled performance, enhances decision support, and simplifies fleet management. The FLIR Si2-LD Industrial Acoustic Imager is perfect for maintenance managers, reliability specialists, and NDT technicians working in manufacturing sectors. This is because it can be used to find potentially expensive leaks and bearing issues before significant costs are incurred.
