    On the left is an image of a man holding the Teledyne FLIR Si124 Acoustic imager pointing it at a collection of electricity pylons. The plant is covered in snow. On the right of the image large, black text on a white background reads "6 Things to Consider Before Buying an Acoustic Camera". Acoustic imaging cameras, otherwise known as sonic or ultrasonic imagers, are popular amongst facilities managers, especially those working in industrial or high-voltage settings. They are extremely easy to use and highly effective at finding air/pressurised leaks and partial discharge/corona. Acoustic cameras detect audible and/or ultrasonic sound; convert it into a sound map; then superimpose this map onto a digital image of the inspection area, allowing you to pinpoint the source of the leak or electrical fault accurately, simply, and quickly. As sonic imaging is a relatively new preventative maintenance/inspection technology, it can be difficult to know what makes a good acoustic camera. Thankfully, Teledyne FLIR has outlined six things to look for when purchasing an ultrasonic imager. Continue reading →
