FLIR Si124 Industrial Acoustic Imaging Camera
The FLIR Si124 is an intelligent, easy-to-use imaging system. It is designed to visually show pressurized leaks in compressed air systems and display partial discharge problems in highvoltage electrical systems.
The FLIR Si124 is extremely light (980g), and therefore easy to handle with one hand. The minimum working distance goes from 0.3 meter (1.0 ft) up to a maximum working distance of 130 meter (430 ft). All this makes this acoustic imaging camera thé solution for compressed air leaks- and partial discharge detection.
Built with 124 microphones and a frequency range that covers audible and ultrasound (2 kHz to 35 kHz), the Si124 sees through background noise commonly found in industrial
environments to produce precise acoustic imagery.
With the FLIR Si124 you are able to find leaks 10x faster and you can reduce electricity waste and optimize equipment performance. Because inspecting with the acoustic imager is so easy to learn, this camera is even for individuals with limited experience the perfect measurement tool.

Electrical applications
The 3 most common electrical errors detected by ultrasound are:
- Arcing
- Tracking
- Corona
The FLIR Si124 has a maximum working distance of 130 meters (430 ft.). Therefore inspecting high-voltage power lines, electrical installations that are hard to reacht, etc. is not a problem at all.
With the FLIR Si124 you always work safe and efficient.

Mechanical applications
Mechanical ultrasound can be used for diagnoses and predictive maintenance of a wide range of mechanical equipment. Examples are:
- Bearings
- Belts
- Pulleys
- Couplings
- Chains
The FLIR Si124 makes it possible to visualize friction. The more friction, the more ultrasound there is. With the help of the FLIR Si124 you can immediately locate the problem. In this way you can intervene to prevent a worse situation.

Leak detection
Ultrasound is ideal for detecting turbulence in gases and liquids. Just like it is the case with more friction in mechanical applications, for pressurized leaks applies: the more turbulence there is, the more ultrasonic sounds.
Steam leaks under high pressure can be life-threatening. Leaks of compressed air are often audible to the human ear. Yet the turbulence generated by these steam leaks is many times higher. This therefore translates into more ultrasonic sounds. So for the FLIR Si124 no problem to detect this.
Factors to take into account when detecting a leak:
- Turbulence
- Shape of the opening
- Pressure differences
- Viscosity of the liquid
- Distance to the leak
- Accessibility to the leak
