Today’s practice In practice, the maintenance centers demand a high level of safety and efficiency. Vehicles that come in for maintenance or repair must be put back on the tracks as quickly as possible. A tricky leakage in the compressed air network can completely mess up the service center’s planning but also that of the ‘customer’, which can lead to high costs. The classic search methods such as hearing, exclusion steps, soapy water, etc. can take hours or even days to locate the leak. Downtime costs are pre- programmed. Fluke solution The Fluke sound camera enables technicians to quickly and easily locate leaks in the compressed air system. The sound source (leakage point) is visualised and precisely localized on the display using 64 ultrasonic sensors and a digital camera. A short tour around the locomotive is enough to get a good ‘picture’ of the situation. Fluke asked a maintenance leader from a German railway operator why Location Railways maintenance site in Germany User/department Service and maintenance technicians, maintenance-technical management, process and work preparations, wagon and locomotive maintenance Application Locating leaks in brake systems Valves in the ventilation system Vehicle components such as sanding system, pantograph and lubrication of the wheels Time savings Greater than 80 % Why use the Fluke ii900 Sonic Industrial Imager? Ease-of-use Quick localisation Versatile application Fluke ii900 was the chosen option: “This innovative technology has excited me from the moment I first heard about it. The imager was primarily purchased for troubleshooting the trains’ pneumatics. We have already seen enormous time savings with complex leakages. After just a few tests, we found how reliable the system is and the versatile ways it can be used. We are very pleased to see the high level of acceptance amongst our service technicians–the ii900 has immediately become a standard tool for us.” www.fluke.com
