6.4.2 Straightening tube
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: (Distance) → 0.2 m
Use of straightening 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
6.4.3 Gooseneck
Before the gooseneck can be used, its data – located on the
USB stick shipped with the attachment – must first be im-
ported into the LD500, if it was reordered.

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 targeted,
local testing of compressed air components at high noise levels, for example in systems using pneu-
matic cylinders and in compressed air distribution cabinets.
Quantification distance (distance) → 0.05 m
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
