Highly sensitive leak detector

The leak detector LD 400 is a handy device for detecting often hidden perforations in pipes and tubes. It is the further development of the proven LD 300 and impresses through a significantly more sensitive sensor technology to provide improved support during the leak detecting process.

The functional principle is ingeniously simple

Leaking gas causes ultrasonic noise. However, a leak must have the size of approximately 1 mm and the pressure must have reached approximately 7 bar before the frequency emits a sound that is audible to the human ear. The leak detector LD 400 can locate leaks in the ultrasonic range, even from a distance of several meters. The LD 400 translates the ultrasonic sound into an audible frequency and makes it easier to detect even the finest holes in the pipes. Sound-proof headphones ensure that the technician can hear the acoustic signal even in the noisy environment of an industrial plant.

Complete discovery of leaks

Additionally, in extremely loud rooms, we recommend the use of a shotgun microphone with a directional tip. It functions like a directional microphone, prevents annoying background noises and also facilitates the precise localization of leaks in inaccessible areas.
Additionally, an ultrasonic transmitter whose signal penetrates through the smallest openings can be used to detect leaks in pressureless systems.

Saving energy and money with high-tech

In Germany alone, 60,000 compressed air systems are using 14 million MWh of electricity each year. “15 to 20 percent of it can be easily saved,” says Peter Radgen of the Fraunhofer Institute in Karlsruhe,
“because a large part of the energy that is used by the systems to generate and constantly maintain air pressure escapes through leaks in the pipes.” In other words: a hole with a diameter of one millimeter results in energy costs of approximately EUR 270 per year. Depending on the size of the facility, the energy saving potential can amount to five- or even six-figure sums.

This representative example demonstrates vividly that the acquisition of the leak detector LD 400 is already profitable with only four leaks. Furthermore, the size of the leak grows through steady pressure of the escaping gas. The permanent burden of energy costs grows too, and thus, the leak detector LD 400 prevents additional cost explosions.

Some useful accessory tools are optionally available for the LD 400. We recommend the leak detector LD 400 Set that includes the most important accessories:
