Leakage Leak detector LD 450 If gases escape through leaks in pressurized pipe systems (e.g. non-tight screwed connections, corrosions and so on), ultrasonic noises are generated. By means of LD 450, even the smallest leakages which cannot be heard by the human ear and which are not visible due to their size can be detected even from distances of several meters. LD 450 transforms the inaudible signals into a frequency which can be identified by human beings. By means of the comfortable sound-proof headset, these noises can be detected even in extremely noisy environments. The LD 450 leak detector is the advancement of the proven LD 300 and LD 400 and it impresses with its significantly refined sensor technology and its improved support in the tracing of leaks. By means of the integrated laser pointer, which serves for target heading, the leak can be localised more accurately. of class I instruments for the norm “Standard Test Method for Leaks • compressed air, gas and vacuum systems • Door seals with Ultrasound” (ASTM Int. - E1002-05) Acoustic trumpet LD 450 with straightening tube and straightening tip for accurate detection. Sound-proof headset: Enables leak detection in an extremely loud environment Costs per year Size of leakage - diameter (mm) Pressure Table: Leakage costs within one year in case of operation 24

Through the use of a specially designed acoustic trumpet, a better bundling of the sound waves is achieved. This trumpet acts like a directional microphone, which bundles ultrasonic waves and thus improves the acoustic behavior. Due to the special design of the acoustic trumpet, the use of the laser pointer is not hindered. Leak test: A handy ultrasonic transmitter is available for detecting leaks in pressureless systems. The transmitter is positioned so that the sound can enter the pipe system. The ultrasonic signal penetrates the small- est openings, which can then be detected with the LD 450....
