The FLIR Si2-PD Industrial Acoustic Imager is a sensitive, simple-to-use, safety-optimised sonic imager designed for pinpointing partial discharge (PD). A perfect condition monitoring tool for the electric, power, and utilities industries, the FLIR Si2-PD Industrial Acoustic Imager is designed to make maintenance managers’, substation managers’, reliability specialists’, and thermographers’ jobs easier and quicker.
Building on the success of its predecessor, the FLIR Si124-PD Industrial Acoustic Imager, the FLIR Si2-PD Industrial Acoustic Imager can detect partial discharge faults thirty times smaller than previously possible and from a safe distance of 200m away from the issue. In addition to this, it includes the following new features:
124 microphones strategically arranged for high performance combined with a 12MP digital camera, and 8x digital zoom, ensures the FLIR Si2-PD Industrial Acoustic Imager can locate and classify PD faults, as well as assess the severity of these defects from up to 200m (656 ft). Such a long detection range not only enables the identification of tricky-to-access issues but also ensures staff are kept safe when surveying dangerous equipment.
One-handed operation and automatic tuning add to the ease and efficiency of the FLIR Si2-PD Industrial Acoustic Imager, maximising inspection productivity.
The FLIR Si2-PD Industrial Acoustic Imager offers best-in-class decision support due to on-camera and software-based severity assessment of partial discharge issues and PD classification. It also provides recommended actions aiding in swift decision-making and suitable response/repair planning. Again, this improves the simplicity and speed of maintenance inspections.
Support for Cloud data integration and OTA software means the FLIR Si2-PD Industrial Acoustic Imager can accommodate enterprise scaling allowing managers to ensure tools are being used and maintained correctly.
As a result of its sophisticated yet simple-to-use design and PD optimisation, the FLIR Si2-PD Industrial Acoustic Imager is perfect for:
A powerful and practical ultrasonic imager, the FLIR Si2-PD Industrial Acoustic Imager empowers you to make precise maintenance decisions, save money, protect the public, and prevent downtime.
