Technical Data Sheet Page 1 of 2 Leakage Detector DLD DLD ultrasonic leakage detector allows maintenance personnel to confirm a diagnosis on the spot by being able to clearly discriminate among various equipment sounds. Product description: If gases escape through leaks ultrasonic noises are generated. By means of the DLD leakages can be detected in the ultrasonic range even from distances of several meters. DLD transforms the inaudible signals into a frequency which can be identified by means of the provided sound-proof headset. In depressurized systems an ultrasonic tone generator can be used of which the signal travels through smallest openings. Cost saving In Germany 60,000 compressed air plants use 14,000,000,000 kWh electrical energy per year. 15 to 20 % could be easily saved (Peter Radgen, Fraunhofer Institut, Karlsruhe). Most of theses costs are caused by leakages in the compressed air system. The air "escapes" unused. 1 leak with a diameter of 1 mm = 270 EUR/year. The DLD will be payed off after 4 leakages The integrated laser faciliates the detection of leaks Applications: Leak detection in • Compressed air lines, gas, vapour and vacuum plants • Refrigerating plants • Door seals Set DLD consists of: • DLD leakage detector • Ultrasonic sensor • Sound-proof head set • Focus tube with focus tip • hole size increases over time • Cable for ultrasonic sensor • the human ear can only hear leakages which are bigger than 1 mm2 at 7 bar • Battery charger • until they are noticed 10 small leaks may cause a loss of 7.000 Euro/ year • Transport case Technical alterations reserved (R01/ 2008/06/11) Donaldson Filtration Deutschland GmbH · Industrial Filtration Solutions · Büssingstraße 1 · D-42781 Haan · Telefon +49/21 29/569-0 · Telefax +49/21 29/569-100
