LD6000 combidetector

Leak detection and acoustic pipe location

Whether you need it for laying out pipes or to narrow down the search or pinpoint a leak the highly-sophisticat­ed LD6000 and the high-quality microphone, which both carry the hallmarks of a product made in Germany, allow you to determine even the tiniest of leaks and display the signal before it is processed.

Principles of Acoustic Leak Detection

Water which escapes from pipes that are under pressure, causes friction which in turn can be picked up in the form of sound waves.
The pipes themselves start to oscillate.
The sound that is generated by these oscillations and friction, is transmitted through the pipes and can be transformed into audible sound with a body sound microphone at a distant contact point (e.g. valve, hydrant, etc).
In addition the water leaking out through the crack or hole in the pipe, generates sound which is carried through the ground to the surface.

This sound can be picked up by a ground microphone and transformed into audible sound.
The microphone from the LD6000 picks up these sounds and displays them on the controller. The noise can also be heard using the headphones.

Benefits in practice:

Acoustic and trace gas leak detection in only one device High-resolution colour graphic display with touchscreen functions The only one of its kind in its class. State-of-the-art smart function for even faster pinpoint leak detection (patent filed) Numerous preprogrammed common applications for quick access All filters and parameters can be configured individually Pipe detection mode Complies with all guidelines govern­ing according to VBG 121 (when used with original headphones) (VBG – trade association safety regulations) Highly-sensitive, high-quality, robust precision microphone made in Germany
