9Overview and application description of the different sensor types
Acoustic trumpet (standard tool)
Straightening tube
The acoustic trumpet bundles incident ultrasonic
waves, thereby extending the range of the device. This
behaviour makes it ideal for medium distances.
The leakage can be heard from large distances, for
precise detection, the user must approach the leakage
and consistently follow the "loudest" point. Individual
compressed air components are then checked for
precise detection.
Quantification distance (distance) 1 –6 m
Use of acoustic trumpet:
•Average distance to pipe/component 0.2 - 6 m
•Low interfering noise
•Leakage freely accessible
•Use at distances of up to 6 metres if no
parabolic mirror available
The straightening tube permits only very few ultrasonic
waves to pass in the direction of the ultrasonic transducer,
allowing leakages to be located very precisely.
For this reason, the use of the straightening tube is
recommended for small distances, for the precise detection
of the corresponding leakage.
Quantification distance: 0…0,2 m
Use of focus tube:
•Short distance to pipe/component 0.05 m
•Pipe/component freely accessible
•Pipes and components to be inspected are very
close together
•Medium to high noise
•Use when no gooseneck available
Gooseneck
Parabolic mirror
The gooseneck should be used if the pipes and
components to be inspected are physically very close.
In addition, the shape of the gooseneck can be flexibly
adapted to easily inspect hard-to-reach pipes and
components.
The sensitivity of the gooseneck has been reduced to
dampen noise. This makes it ideal for target-ed, local
testing of compressed air components at high noise
levels, for example in systems using pneumatic
cylinders and in compressed air distribution cabinets
Quantification distance →0 …0.05m
Use of gooseneck:
•Short distance to pipe/component 0.05 m
•Leakage not freely accessible
•Medium to high ultrasonic noise
•Pipes and components to be inspected are
very close together
The parabolic mirror bundles horizontally incident
ultrasound in its focal point where the ultrasonic transducer
is located. On the one hand, this leads to a considerable
amplification of the measured ultrasound (high range) and,
on the other hand, to a very precise directional behaviour,
since ultra-sound that does not incident horizontally is
reflected by the reflector.
The combination of these two characteristics enables the
parabolic mirror to precisely locate leaks at large distances.
Quantification distance →3 –12 m
Use of parabolic mirror:
•Large distance to pipe/components 3 –15 m
•Interfering noise
•Leakage not freely accessible (behind a fence)
•Near leaks (superimposition))

9.1 Assembly with acoustic trumpet
The acoustic trumpet allows acoustic amplification by bundling the sound waves and specifies the
location of the leak. Due to the special construction of the integrated laser pointer is still usable. The
camera is integrated on the bottom of the acoustic trumpet and is electrically connected to the
preamplifier module via the jack plug.
Assembling is done by plugging the individual components until easy locking audible (plug in to the
stop).
The components are removed in the reverse order; for unlocking the preamplifier module, the release
button must also be pressed.
9.2 Assembly with focus tube with focus tip
The focus tube with focus tip is used to detect very small leaks, to accurately locate them.
Just like the acoustic trumpet, the tube can be plugged into the preamplifier with ultrasonic receiver.
The use of the camera is no longer possible.
The components are removed in the reverse order; for unlocking the preamplifier module, the release
button must also be pressed.
