Overview 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
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
