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 ILD 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. ILD 450 transforms the inaudible signals into a frequency which can be identified by human beings. By means of the comfortable soundproof headset, these noises can be detected even in extremely noisy environments.

The ILD 450 leak detector is the advancement of the proven ILD 300 and ILD 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. 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.

The ILD 450 meets the requirements of class I instruments for the norm “Standard Test Method for Leaks with Ultrasound” (ASTM Int. – E1002-05)
